Objectives : This work is aimed to reveal the relations between concepts of subhealth(mibyung) and Korean medicine patterns. Methods : We carried out a literature searching on Oasis, RISS, DBpia, Pubmed to summarize concepts of Mibyung. CNKI Searching also was performed with keyword related to mibyung(未病), subhealth(亞健康) and syndrome. Results : Korea, China and Japan have different concepts of mibyung. China's mibyung concept is relatively broader and wide which includes healthy, subhealth, development of disease and recurrence avoid. In contrast, Korea and Japan's mibyung concepts are focused on China's subhealth. Though Mibyung's patterns are varied widely depends on studies, China's studies of subhealth and TCM patterns showed that Deficiency patterns are diagnosed at high frequency in clinical study and literature study. Conclusions : This work could contribute to further study of subhealth(mibyung) and their relations to patterns, diagnostic methods and treatment efficacy.

1. Objectives: We report the relation between the questionnaire and the health state on the Sasang Constitution. 2. Methods: We carried out a clinical test, in which 2 Oriental medical doctors participated to diagnose health state in each Sasang Constitution with 239 subjects. The subjects were divided into 3 subgroups, which are allocated to healthy group, poor health group and disease group. 3. Results: We extracted 4 questions for Taeeumin, 5 questions for Soyangin and 3 questions for Soeumin from the whole 98 questions respectively. Soyangin and Taeeumin share a same question that shows significant difference by health status. For the statistical analysis, we used a Chi-square test. As a result, we found out that Taeeumin showed different distributions of answers in direct/indirect characteristic, perspiration, frequent urination, regular defecation. According to the health status Soyangin showed the different distribution of the answers in color of urination, frequent urination, mouth dryness, abnormal perspiration, discomfort of head. Soeumin showed the different distribution of the answers in cold and chilly feel of abdomen, digestion status and cause of digestion problems when body condition gets worse. 4. Conclusions: This is the first work which reports the relatedness between Questionnaire and Health State in each Sasang Constitutions by an objective clinical test. We found out that several questions have different distributions by health status in each Sasang Constitution. These extracted questions are categorized not only by Wansilmoobyung(완실무병), but also by other symptoms and body status.

Structure of Upwelling off the Southease Coast of Korea

이재철,나정열,Lee, Jae-Chul,Na, Jung-Yul The Korean Society of Oceanography 1985 韓國海洋學會誌 Vol.20 No.3

Hydrographic data and daily time series of longshore wind, sea level and sea surface temperature were used in order to explain why the upwelling effect in SST is especially prominent near Ulgi-Gampo although the sea level records along the whole southeast coast show a nearly uniform upwelling-downwelling response to wind. Regional difference in intensity of the wind-induced upwelling represented by the SST decrease is attributed to the combined influence of two factors; one is the baroclinic tilting of isotherms due to the East Korea Warm Current (EKWC) near the Ulgi-Gampo coast, the other is the topographic effects around the southeast coast. Baroclinic tilting effect of EKWC which is generally strongest near the coast of Ulgi to Gampo results in both of the shoaling of cold water and the westward trapping of the coldest bottom water over the shallower shelf rather than the deepest troough region off that coast regardless of the season. Therefore, becacse of the cold water ready for upwelling at the subsurface layer, SST responds very rapidly to the upwelling-favorable winds of summer only off the Ulgi-Gampo coast. Spreading isobaths from Pusan to Gempo can reinforce the upwelling of the cold bottom water and its westward trapping.

연구배경: 다제 내성 폐결핵 환자의 임상적 특성과 약제별 내성률, 치료에 영향을 미치는 인자, 이차 약제로 인한부작용, 치료내용 및 차료성적 등을 살펴 보고자 하였다. 대상: 약제 감수성 검사상 두가지 이상의 일차 약제에 동시 내성을 보이는 환자를 대상으로 후향성 연구를 시행하였다. 치료 결과의 판정은 정기적으로 6개월 이상 추적 관찰이 가능했던 환자만을 대상으로 치료후 호전을 1개월 이상의 간격으로 시행한 가래 검사상 3회 이상 음성이고 방사선 소견이 호전되거나 6개월 이상 변화가 없는 경우로, 치료 실패를 6개월간의 치료에도 균 음전화가 되지 않거나 방사선 소견상 악화를 보이는 경우로 정의하였다. 대상 환자들은 감수성 검사 결과에 따라 감수성 약제를 4제 이상 투여하여 치료받았다. 결과: 1) 총 71예와 환자를 대상으로 조사한 결과 35예(49%)에서 방사선상 공동을 관찰할 수 있었고 평균 4.1개의 약물에 내성을 지니고 있었는데 90%가 INH, RFP 동시 내성을 보였다. 2) 치료 결과의 판정이 가능하였던 55예중 35예(67%)의 환자가 치료후 호전을 보였으며 치료 실패는 18예(33%)이었다. 일차 내성 환자가 5예이었는데 치료 결과 판정이 가능하였던 4예는 모두 치료에 성공하였다. 3) 약제 부작용은 14예(20%)에서 나타났는데 간기능 악화가 6예로 가장 많았고 어지러움증 5예, 고요산 혈증을 동반한 관절통이 3예, 이명 3예 등의 순이었다. 이들 부작용의 절반 이상이 투약후 3개월 이내에 발생 하였다. 4) 약제 감수성 검사를 반복했을 때 INH, RFP의 경우 100% 가까운 일치율을 보였고 EMB, PZA 80% 정도 나머지 약물은 50% 미만이었다. 5) 5예의 환자가 수출을 받았고 이 중 1예는 항결핵 화학 요법의 보조적 치료로 수술을 했는데 균 음전화에 성공하였다. 결론: 다제 내성 폐결핵 환자에서도 규칙적인 약물 복용과 적절한 처방으로 약 2/3 정도에서 호전이 관찰되어 적극적인 항결핵 화학 요법을 시행해야 할 것으로 생각되지만 치료와 예후 판정에 도움이 되는 인자를 찾지는 못하였다. Objectives: Although outbreak of MDR Tb has been a recent problem in western countries, it has been a longstanding problem in Korea. The poor outcome of MDR Tb is mainly due to poor compliance, high rate of side reaction of secondary drugs, and limitation in number of available drugs. Thus, to improve the outcome of MDR Tb, it is crucial to make individualized adequate prescription based on the knowledge of the patterns of resistance to each drugs in the community as well as the natural history. The purpose of present study is to evaluate the clinical features of Korean MDR Tb patients including patterns of drug resistance and success rate of treatment which was prescribed according to the sensitivity tests. Methods: Retroscpective analysis of 71 Korean patients with MDR Tb was made. All strains isolated from patients showed resistence to at least two first line drugs. Patients profile, previous treatment history, patterns of drug resistance, outcome of treatment was analysed. Initial treatment regimen was selected according to the previous treatment history and was modified according to the sensitivity reports. The regimen was composed to include at least 4 sensitive drugs when possible. Results: The patients showed resistance to 4.1 drugs on average. 90% of them were resistant to INH and RFP. Among 71 patients, 35 patients(49%) had cavitary lesions in CXR. Treatment outcome was analysed in 55 patients. 35 patients(67%) were improved after treatment and 18 patients(33%) showed treatment failure. 5 patients showed primary resistance. Treatment outcome could be evaluated in 4 of them and all showed improvement after treatment. 14 patients(20%) had to change their regimens due to drug side effects. The most frequent side effect was elevation of liver enzymes(6 patients). Others included dizziness, hyperuricemia, tinnitus, skin rash, GI troubles. More than 50% of side effects developed within 3 months. In repeated drug sensitivity test, the concordance rate of resistance to INH was 100% and RFP 98%. EMB, PZA showed 80% concordance rate. But in the other drugs, the concordances were less than 50%. Operation was done in 5 patient - 1 patients as a adjunctive means of chemotherapy -. In that case, negative conversion of sputum AFB was done. Conclusion: 2/3 patients of multidrug-resistant tuberculosis were improved by appropriate prescription and regular medication suggesting that more aggressive management and monitoring is indicated in multidrug-resistant tuberculosis.

2006년 봄철 광양만 해류의 구조와 변동

이재철,김정창,Lee, Jae-Chul,Kim, Jeong-Chang 한국해양학회 2007 바다 Vol.12 No.3

광양만의 순환을 이해하기 위하여 2006년 봄철에 수심이 가장 깊은 두 지점을 선정하여 ADCP가 장착된 모니터링 부표 2대를 이용하여 유속관측을 하였다. 두 지점에서 공통적으로 북향류가 지배적인데, 이는 서쪽의 남향류를 동반하는 반시계 방향의 순환 이 있음을 뒷받침 하고 있다. 남쪽에서는 14 m 수심에서 유향이 반전되는 2층 구조가 뚜렷하며 저층의 북향류는 바닥에 가까운 36 m 수심까지 증가한다. 북쪽 지점에서는 북향류가 더욱 강해져서 북쪽의 단면적 감소에 따른 해류의 가속 효과가 있으며 상층부에서도 북향류가 우세하다. EOF 분석을 통한 연직구조에 있어서 첫 번째 모드는 북쪽 부표에서 전체 분산의 74%인데 비하여 남쪽 부표에서는 67%로 감소하고 상대적으로 2층 구조의 비중이 크다. 반시계 방향의 순환과 관련된 북향류의 전형적인 유속은 약 10 cm/s이다. 여기에 중첩되는 변동성으로서 국지적인 바람의 영향은 거의 받지 않는 반면에 동-서 방향의 바람에 의한 외해의 에크만 수송과 관련된 비국지적 영향은 주로 풍속이 강할 경우에 나타난다. Two monitoring buoys equipped with ADCP were deployed at the deepest positions along the trough of the central Gwangyang Bay in spring 2006 in order to study the circulation in the bay. Northward velocity is commonly dominant at both stations located in the eastern part of the channel, which supports the cyclonic circulation accompanied by the southward flow in the western part. The southern station has a distinct two-layer structure with current reversal at 14 m depth and increasing northward velocity in the lower layer to 36 m depth close to the bottom. At the northern station the northward flow becomes accelerated due to the decrease in the cross-sectional area and this northward current is dominant even in the upper layer. In the modal structure from the EOF analysis, the first mode has 74% of total variance at the northern station whereas it is 67% but the baroclinic portion increases at the southern station. The typical northward velocity is about 10 cm/s which is associated with the cyclonic circulation. Subtidal variability due to the local wind effect is negligible, but the nonlocal response associated with offshore Ekman flux by the zonal wind is found during strong wind events.

夏季 韓國 南東海域에서 湧昇과 關聯된 바람, 海水面 및 表層水溫의 變化 TEVARIATIONS OF SEA LEVEL AND SEA SURFACE TEPERATURE ASSOCIATED WITH WIND -INDUCED UPWELLING IN THE SOUTH

이재철,Lee, Jae Chul 한국해양학회 1983 韓國海洋學會誌 Vol.18 No.2

Extensive wind, sea level and sea surface temperature (SST) data collected along the east coast of Korea in 1973-1979 were used to ascribe the variations of sea level and SST associated with wind forcing during summer. Alongshore components of wind were dominant but the offshore components were little significance in the southeast coast in summer. The variations in SST and sea level adjusted barometricallyagreed with the upwelling-downwelling processes and showed a rapid response to wind.Appearance of cold water to the surface in the upwelling region concurred well with te periods of positive y-component wind when the tangential line at Ulgi was takem as the y-axis. In general, SST at Ulgi and Gampo as well as the adjusted sea level at Pohang, Ulsan and Busan decreased significantly when strong winds favorable for upwelling persisted for more then three days whereas they increased during the relaxation or unfavorable periods. The period of an upwelling event, on the average, was about 10 days and the mean speed of alongshore sind was 4.0m/sec.

초겨울 大韓海峽에서 形成되는 淺海前線의 構造

이재철,나정연,장선덕,Lee, Jae Chul,Na, Jung Yul,Chang, Sun-Duck 한국해양학회 1984 韓國海洋學會誌 Vol.19 No.1

Mesoscale thermohaline structures of the meandering front in the Korea Strait during November 1976, 1980 and 1982 are studied by means of closely spaced oceanographic observations and the satellite infrared images. Strong thermal and salinity fronts coincide each other and show a wavelike meander motion with wavelengths of 40-60km and amplitudes of, 15-20km. Salinity minimum band of less than 33.0 is found along the onshore edge of the front. Width of the frontal zone corresponds approximately to the internal radius of deformation (R=5-10km) and the slope of density interface is confined to about 2R. A series of satellite infrared images with the interval of 4-5 days show a noticeable growth of frontal meander over the flat shelf west of the Korea Strait. Possible mechanisms of frontal meander and its growth are discussed.
