  • Despite the expansion of sewage treatment facilities to reduce pollutants in the tributaries of the Han River, water pollution accidents such as fish deaths continue to frequently occur. The purpose of this study was to identify the pollutant sources using water quality and stable isotope ratio (${\delta}^{15}N$, ${\delta}^{13}C$, ${\delta}^{15}N-NH_4$, ${\delta}^{15}N-NO_3$) analysis results in the three inflow tributaries (Gulpocheon (GP), Anyangcheon (AY) and Sincheon (SC)) of the Han River. Water quality was analyzed in June and October from 2013 to 2017, and the results showed that the concentrations of nutrients, such as T-N, $NO_3-N$, and T-P, were increased at GP4, AY3, SC3, and SC4, which lie downstream of sewage treatment facilities. The results of ${\delta}^{15}N$ for June 2017 indicated that the source of nitrogen was sewage or livestock excreta at GP4 and SC4, and organic fertilizers at AY3 and SC3. ${\delta}^{15}N-NO_3$ results suggested that the source of nitrogen was related to organic sewage, livestock or manure at GP4, AY3 and SC4. Therefore, GP4 and SC4 were more influenced by effluent from sewage treatment facilities than by their tributaries, AY3 and SC3 were considered to be influenced more by their tributary than effluent from sewage treatment facilities. With the results of this study, the source of contamination (sewage treatment facility effluent) of river inflow downstream of Han River could be confirmed using water quality and stable isotope ratio.

  • Review of literature on the symptoms of sweat. According to comparative studies of oriental and occidental medical literature on the symptoms of sweat, following results were obtained. 1. oriental medicine 1) time: ja han (自汗), do han (盜汗) 2) body : du han (頭汗), su jog han (手足汗), sim han (心汗), eum ban (陰汗) pyun hang (偏汗) 3) kan (肝) : hwang han (黃汗), sim(心) : sin han (心汗), hyul han(血汗), bee (脾) : sig hu han (腎虛汗) sin(腎) : eum han (陰汗) By the study of the oriental medical literature, sweat were concerned with physiological function and pathological transformation of the body, 2. occidental medicine 1) NO sweat of the whole body 2) NO sweat of the part 3) much sweat of the whole body, 4) much sweat of the part. By the study of the western medical literature, sweats were tiny reaction of the· nerve and the mind.

  • This paper deals with a general review of Mieko S. Han, who made a significant contribution to the studies of Korean phonetics during the 1960' s and early 1970' s. As both a single and joint author, Dr. Han published important papers in both quantity and quality, which have been cited among Korean phoneticians until today. Before Dr. M. Han' s work, professor of USC in the department of East Asian Languages & Cultures, there were only a few phonetics-related publications in Korea, most of which are papers or books based on non-experimental traditional approach. It is known that there was coexistence between traditionalism and structuralism in the field of Korean linguistics. It was, however, fortunate that we had two important phoneticians (M. Han and Chin-W Kim) abroad at that time. Mieko Han' s concern was to investigate experimental characteristics of the system of Korean vowels and consonants using a Spectrograph, which was the single most important tool for analysing phonetic data at that time. Dr. Han conducted her experimental studies on Korean phonetics, mostly funded by the Office of Naval Research, in terms of duration, fundamental frequency, Voice Onset Time (VOT), intensity, and so on. This paper aims to re-appreciate Dr. Han's specific contribution to the study of Korean phonetics since she played an important role as a pioneer of early Korean phonetics. Further, it is highly recommended that Dr. Han's works can be extremely useful for a graduate student, who seriously would like to specialize in Korean phonetics in the first step.

  • 상황인지(Context-awareness)란 사용자의 상황을 인지하여 이를 통해 사용자에게 적합한 최적의 정보를 제공하는 것으로 현재 많은 연구가 진행되고 있다. 이미 상황인지를 위한 프레임워크들이 존재하지만, 작은 메모리가 요구되는 제한적인 하드웨어 상황에서 적용하기에 적합하게 설계된 프레임워크는 흔하지 않다. 이에 대한 문제점을 인식하여 하드웨어 리소스가 부족한 상황에서 빠르게 동작할 수 있는 프레임워크를 구상하여, 기존과는 다른 제한적인 환경 안에서 상황인지를 통해 사용자에게 맞는 최적의 서비스를 판단, 제공하는 모바일 오브젝트를 설계하였다.

  • Objective : To collect cosmetology text in Shang Han Za Bing Lun(伤寒杂病论), to analyze theory and prescription about cosmetology before HAN(漢) dynasty, so to allow records for modern cosmetology of Traditional Chinese Medicine. Method : Through the systematize for all terms about cosmetology, to reveal the regularity about cosmetology before HAN(漢) dynasty. Result : There were damage-appearance disease in HAN(漢) dynasty, there are lots of ideas about cosmetology in Shang Han Za Bing Lun(伤寒杂病论). Conclusion : Shang Han Za Bing Lun(伤寒杂病论) is a monograph about pattern identification and treatment, and is an important ancient book for research of cosmetology of Traditional Chinese Medicine. In the further, we will research in knowledge discovery about cosmetology of Traditional Chinese Medicine. to strengthen the guidance of the theory of Zhang Zhongjing(张仲景) for clinical practice of cosmetology of Traditional Chinese Medicine.

  • The droplet behavior of 83.9 wt.% HAN water solution was investigated experimentally with various ambient temperature and nitrogen environment. At the initial stage of evaporation under thermal decomposition temperature of HAN, gradual decreasing of droplet diameter was observed. After that, the droplet started to expand due to the internal pressure build up by water nucleation inside the droplet. The micro explosion was observed at higher temperature than the decomposition temperature of HAN and the remaining droplet showed similar behavior of single composition droplet. The decreasing rate was augmented as the ambient temperature increasing.

  • The purpose of this study was to develope the Contemporary Han-ok based on the natural environment characteristics of mountainous territory in Gangwon-do. According to the result of this study, Eco-friendly Contemporary Han-ok adaptable to the natural environment feature focused on the local climate was proposed based on the tradition of mountainous territory housing in Gangwon-do. In addition, proposed Mountainous Han-ok in Gangwon-do planned to keep the out feature of traditional Korean Han-ok and have the environmental control system same as traditional Korean Han-ok. Despite of several limits, this study has the meaning in terms of propose the prototype of adaptable contemporary han-ok based on the Natural Environment Characteristics of Mountainous Territory and regional tradition in Gangwon-do in cognition of local natural environment difference. the proposal of contemporary han-ok as the result of this study will give a support to the wide planning of Han-ok and the development plan of contemporary Han-ok.
