The hakgil is the important disease in the oriental medicine historically. In the preseant time also this disease continually appear all over the world. So purpose of this study is that consider the symptoms and pathogenesis of hakgil(瘧疾) with the point of view of oriental medicine. And in this study, the results are summarized as the followings. 1. The symptos of hakgil(瘧疾). 1) Rigor and heat spasm : The main symptoms of hakgil is the severe and periodical rigor and heat spasm. Generally the rigor first appear and later the heat spasm appear. According to the first and last, severe and weak, the hakgil is classified to hanhak(寒瘧), onhak(溫瘧), danhak(癉瘧), binhak(牝瘧). 2) The regulation of the time of spasm : The spasm occour in the same time daily or one time in two days, three days or several days. And the spasm time is regulary in day or night. 3) The term between the spasm and next one become later or faster. It can be decided that the becoming worse and better in the disease with the signs. 4) The seasonal property Generally the hakgil appear in summer and early autumn. 5) The other kind of hakgil there are five-organ hakgil(五臟瘧), six-kyung hakgil(六經瘧), janghak(瘴瘧), kuihak(鬼瘧), six-gi hakgil(六氣瘧), damhak(痰瘧), sikhak(食瘧), and so on. 6) The pulse condition of the hakgil is chiefly hyun(弦). 2. The pathogenesis of the hakgil 1) The cause of the hakgil The causes of the hakgil first are the seo(暑) or heat(熱) that make the problem in the cycle of five phases(五行). In the consequence, il open the hole of skin so that the pathogenic factors easily invade the humanbody and at the same time the pathogenic factor in the inside easily come out, that make the spasm. In the second time the pathogenic factor of yin(陰) - wind(風), cold(寒), water(水) invade through the opened skin to combine with the factor in the inside. Such condition make the hakgil and the accessory spasm. 2)The pathogenesis of hakgil(瘧疾) (1) The rigor and heat spasm of hakgil(瘧疾) appear because in summer the human body don't accomplish a task of summer because of hot weather or heat, so in autumn the ki(氣) of human body separate into yin(陰) and yang(陽), and the skin of human body is weaken so the saki(邪氣: pathogenic factors) is easily come into the human body. At this time the circulation of ki(氣) is obstructed, so the jungki(精氣: vital substance) apply to straighten the circulation of ki(氣), if the jungki(精氣: vital substance) help the yin(陰) the rigor spasm appear in the opposit direction the jungki(精氣: vital substance) help the yang(陽) the heat spasm appear. (2) The period of circulation of ki(氣) and jungki(精氣: vital substance) is one day, so the general period of spasm of hakgil(瘧疾) is one day, But if the saki(邪氣: pathogenic factors) come into the human body deeply, the jungki(精氣: vital substance) cannot apply 10 straighten the circulation of ki(氣) every day so the period of spasm become longer.

The following conclusions are produced by the consideration of Bojungikki-tang(補中益氣湯) from the view point of Hyungsang medicine. A review on the explanation and provisions of Bojungikki-tang stipulated in 'Donguibogam(東醫寶鑑)' results in the idea that the main purpose of Dongwon(東垣) and various application in clinic by Jeesan(芝山) cannot be understood without the deep comprehension of ki(especially Jungki and Wonki) and the fire. Jungki(中氣, the middle warmer ki) is the ki of stomach. Wonki(元氣, the original ki) is a combination of innate Jung(先天之精, Ki stored between the two kidneys) and acquired Jung(後天之精, Ki of the stomach) and the sources of five Jang and six Bu, twelve meridians and triple warmer. Yin fire is referred to the ministerial fire of spleen, liver and kidney. Excess or lack of the ministerial fire can cause a disease and especially the excess of it is harmful to original ki. Deficiency of original ki is thought to be a cause of allergic diseases. Damages on the original ki by the abdominal surgery lead to a disease. Pale complexion, long face and the long limbs are considered as the Hyungsang of deficiency of Jung ki by Jeesan. Clinical cases of Bojungikki-tang in Hyungsang medicine draw the following conclusions ; Bojungikki-tang is usually prescribed to the person who has one of the following Hyungsang : Bangkwang type, pale complexion, long face, short-sight, astigmatism and wrinkles on face. Bojungikki-tang can be applied to the every disease caused by the deficiency of original ki regardless of name and symptoms of disease.

Laser sealing with glass frits appears a promising technology for sealing various electronic devices (e.g., solar cells, displays) due to its several advantages. The purpose of this study is to understand the relationship between the composition of glasses and their laser-heating conditions. To allow glass to be sealed using laser heating, CuO was added to two different glass systems, in different amounts. The optical absorptivity of the glass samples was related directly to their CuO content. The laser-heating temperature and the CuO content exhibited a proportional relationship. Furthermore, the heating temperature increased linearly with the laser power used. From these results, we could determine the appropriate laser-heating conditions and CuO content for sealing electronic devices using laser-sealing technology.

This study compares the ethical inclination regarding consumer misbehaviors from two countries with contrasting cultural characteristics. National samples of South Korean and American adults provided their perceptions of the appropriateness of 12 ethically questionable consumer actions. The scenarios ranged from illegal actions, such as fraudulently inflating one's losses when filing an insurance claim to legal, yet questionable, actions such as purchasing an item that the buyer recognizes as having been mispriced. The 12 scenarios exhibited a wide range of mean responses in both countries, thereby supporting the oft-stated premise that consumer ethics is a situational phenomenon. Findings indicate not only where the cultures diverge but also where they converge towards a degree of congruence. Plausible explanations for differences based upon cultural dynamics are provided.

As a result, the investigation into Gyung-Ak (景岳)'s theory of Myungmun (命門) was led to the next conclusions. First, Gyung-Ak (景岳) defmed Myungmun as the gate of Suncheon (先天) and Whoocheon (後天), by which the life of Suncheon is obtained and the life of Whoocheon is maintained. He maintained that Myungmun is located between two kindneys, not sided to the right as in the Nankyeong (難經), and considered the substance of Myungmun as Jagung (子宮 ${\fallingdotseq}$ uterus) or the other names as such Jaho (子戶), Jajang (子腸) Danjeon (丹田), Hyeolsil (血室), etc. On the essence or function of Myungmun it was considered as Taegeuk (太極) of the body which shapes the North Pole in the center of the body, and as the hinge of rise and fall, as controller of Soowha-action (水火作用) and Eumyang-changing (陰陽變化), and as storage of Suncheon Jinil-ki (先天 眞一之氣), the source of life and vitality and as the spring of Twelve-Jang (十二藏). Thus, the function of Five-Jang (五臟 ${\fallingdotseq}$ Five-Viscera) and Six-Boo (六腑 ${\fallingdotseq}$ Six-Bowels) and actions of life is obtainded by Myungmun, and the life and death of man and the change of life is related to that. Bi-Wi (脾胃 ${\fallingdotseq}$ Spleen & Stomach) as well as Myungmun is the root of Five-Jang and Six-Boo, but since Bi-Wi is the base of postnatal nutrition to belong to the son of Wonyang (元陽), Myungmun is treated more important as the mother of Bi-Wi. Sin (賢 ${fallingdotseq}$ Kidney) was perceived as inseparably related with Myungmun, but in the course of theoretical development the function of Sin was considered to be ultimately operated by the action of Myungmun. In the Theory of Jineum (眞陰論), Gyung-Ak full accounted the diverse nature of disease and patholog from Soowha-shortage of Myungmun, and presented the laws and methods of medical treatment to those. Finally, in his theory related to Myungmun, some logical contradiction and confusion in conceptions was discovered and the anatomy of Present age proved that the location of Jagung and DanJeon, which he recognized as the substance of Myungmun is not coincided. Summerizingly, the Gyung-Ak's theory of Myungmun closely related the theory of Myungmun to the theory of Eumyang-Jungki (陰陽精氣論), by whole discourse of the characteristics of physiology possessing Soowha of Myungmun on the foundation of Eumyang-hogeun (陰陽互根) and Jungki-hosaeng (精氣互生). Gyung-Ak regarded the function of Myungmun as more important than any other Jang, discoursed more systematically and more specifically about the Myungmun than any others, and presented the theory of Sin-Myung (賢命理論) and prescription which is important to Care of Health and Medical Treatment (養生治病), thus influenced very greatly on the development of Oriental Medicine.

Ag thick-film has usually been used for the front electrode of Si solar cells with the outstanding electrical properties. Ag paste consists of Ag powers, vehicles, frits and additives. Ag paste has broadly been screen-printed on the front side of Si wafer with the merits of low cost and simplicity. The optimal contact formation between Ag electrodes and Si wafer in the front electrode during a fast firing has been considered as the key factor for high efficiency. Although the content of frit in Ag pastes is less than 5wt%, it can profoundly influence the contact formation between Ag and Si under the fast firing. In this study, the effects of lead-free frits on the contacts between Ag and Si were studied with the thermal properties and compositions of various frits. Our experimental results showed that the electrical properties of cells were related to the interface structures between Ag and Si. It was found that current path of electrons from Si to Ag would be possible through the tunneling mechanism assisted by tens of nano-Ag recrystals on $n^+$ emitter as well as Ag recrystals penetrated into $n^+$ emitter layers. These preliminary studies will be helpful for designing the proper frits for the Ag pastes with considering the properties of various Si wafers.

Purpose : Balanced meal service is very important for the elderly to maintain good physical health. Good food and comfortable dining environment is also important for the elderly to prevent emotional depression. The purpose of this study is to investigate current problems of dining space in Korean elderly welfare facility. De-institutionalizing dining environment of elderly welfare facility will bring more meaningful social interactions among elderly users. Methods : Through literature research and case studies of welfare centers in the US and Japan, Elderly Dining Space Checklist was developed. Dining spaces of 11 welfare facilities in Seoul was analyzed by this checklist. It was administered by interior designers as well as facility staffs to achieve more credible results. Questionnaire for the elderly users of those dining space also prosecuted to broaden knowledge for creating improved environment. Results : Dining spaces of elderly welfare centers are lack of privacy and furnitures are not comfortable enough for the general users as well as wheelchair users. Elderly dining space users are seeking more private and comfortable spaces for the social communications. Implications : Dining environment for the elderly in Korea should develop more de-institutionalized design concepts.
