  • Objective : Despite the high prevalence and clinical importance of panic disorder, studies on the clinical characteristics and course of panic disorder are relatively rare. This study is a multi-center, and retrospective study to examine the clinical characteristics and course of Korean panic disorder patients who visit university hospital. Methods : The study subjects were panic disorder patients who had visited the psychiatric outpatient clinics of 8 university hospitals in South Korea from January to December in 2008. Finally, 238 panic patients were included in this study. Their medical charts were retrospectively reviewed and reassessed by experienced psychiatrists to examine their clinical characteristics, demographic data and clinical course in repose to pharmacotherapy. Results : Among the 238 patients (121 males vs. 117 females), the mean age of disease onset was $41.3{\pm}12.7$ years and female patients showed 5 years older age of disease onset, compared with male patients. The mean score of PSR scale was $4.5{\pm}1.0$ at the first visit, reflecting a 'marked' level of severity of illness and impairment in functioning. Only 110 patients (46.4%) completed the whole follow up visits, whereas 128 patients (53.6%) dropped out during the treatment. After $17.7{\pm}0.5$ months of mean follow up period, the mean score of PSR scale at the last visit was reduced into $2.1{\pm}0.9$, reflecting a 'residual' severity of illness and impairment in functioning. The cumulative recovery rate was 62.1% in the completer group, whereas that of the drop-out group was 47.7%. Conclusions : The mean age of disease onset in Korean panic disorder patients who had visited university hospital was about 10 years older than that of Western panic disorder patients in previous studies, and the Korean panic disorder patients who had visited university hospital showed a relatively higher cumulative recovery rate. These differences might result from an ethnic difference in clinical characteristics and course in response to pharmacotherapy of panic disorder.

  • 동아프리카 열곡대는 아라비아반도와 아프리카 북동부의 경계에서 부채꼴 형태로 남쪽으로 뻗은 대단층 함몰지구대이다. 아프리카 판 내부에 발달한 열곡대의 폭은 35~60 km이며 연장은 약 4,000km로 알려져 있다. 열곡대는 에티오피아에서 남서방향으로 발달하다 에티오피아 남부에서 동, 서 및 남서 열곡대로 나누어진다. 이 열곡대는 제3기초 올리고세(30~35 Ma)부터 에티오피아 북부 아파르 침강대를 중심으로 주 에티오피아 열곡대가 형성되고, 남쪽으로 확장되면서 마이오세에 활성화된다. 서부 열곡대는 동아프리카대지의 가장자리와 빅토리아 호의 서편을 따라 발달하며, 고각의 정단층에 의해 특징되는 전형적인 반지구대이다. 동부 열곡대(주 에티오피아 열곡대와 케냐 열곡대)는 30 Ma 전 화산활동과 지구조활동이 시작되었으나, 서부 열곡대는 Albert 호 북부에서 12 Ma 전에, Tanganyika 열곡에서는 7 Ma 전부터 시작되었다. 서부 열곡대의 남서 방향으로 분기된 남서 열곡대는 DR-콩고 남부와 잠비아의 Tanganyika 호에서부터 남서 방향으로 확장되어 보츠와나 Okavango 열곡대와 연결된다. 주 에티오피아 열곡대(MER)의 화산암류와 관련 퇴적암류는 지열, 소다회, 포타쉬(K), 천열수 금, 벤토나이트, 유황 및 부석자원으로 중요한 관련암으로 역할을 한다. 열곡관련 대표적인 광상으로는 Afar 열곡대에 분포하는 Danakhil K-광상과 Megenta 및 Blackrock 천열수 금광상이다. Danakhil K-광상은 제4기 화산활동과 높은 지열류에 의해 열곡대 내 분포하던 소금 선상지(salt fan)에서 증발작용에 의해 형성된 증발형 K-광상으로서 총 자원량은 약 12.6억톤으로 평가되었다. 이 광상에서는 4종의 K-광물인 실바이트, 카날라이트, 포리하라이트, 카이나이트가 산출한다. 아파르 침강대 내 분포하는 대표적인 천열수 금광상은 텐다호 지구대에 위치하는 Megenta 및 Blackrock 광상이다. 제4기에 EMR에서 산성의 과알칼리 화산활동에 의해 열수활동이 초래되어 현재까지도 활동하여 지열대가 형성되고, 저유황형금 광상들이 형성되었다. Megenta 저유황형 금 광상은 2009년 발견되었으며, 현재 영국의 Startex International사에 의해 탐사가 진행 중이다. 지금까지의 탐사 결과 옥수질 규화 변질암 분포지에서 5개의 광체가 분포하며, 그중 Hyena 광체에서는 규화 변질된 열수각력암에서 최고 16.75 g/t의 금 품위가 보고되었다. 동아프리카 열곡대의 서편인 부룬디에 분포하는 Gakara REE 광상은 카보너타이트 유형의 REE 광상이다. 이 광상은 $400km^2$ 면적 내 수 cm부터 수 m까지의 폭을 가지는 맥상 또는 망상세맥상의 광체를 형성한다. 주로 조립의 바스트너사이트와 모나자이트로 구성된다. 바스트너사이트의 형성시기는 $587{\pm}4Ma$인 신원생대로 알려져 있으며, 이 지역에 분포하는 카보너타이트와 알칼리암들이 신원생대에서 신생대까지의 광범위한 연대를 보이는 것은 동일한 구조선을 따라서 일어나는 반복되는 열곡활동으로 해석된다. 또한 REE, U, 인회석 자원의 관련암체로 생각되는 알카리 조면암(네펠린-조면암 포함)과 카보너타이트는 동아프리카 열곡대의 남동부 끝자락인 말라위와 모잠비크에 우세하게 분포한다.

  • This paper presents a scientometric analysis of national patterns of research output and priorities in the sub-fields of Hepatitis covered in three bibliographic databases namely MEDLINE, CINAHL and IPA. The literature covered in three databases for the period 1984-2003 was considered. We have already discussed the Trends in the Growth of Literature on Hepatitis in our previous paper. Therefore in this paper only sub-fields analysis is presented. It has been found that the Hepatitis literature output has been grouped in 23 major sub-fields based on databases covered. It was found that there were high priorities for some of the sub-fields of Hepatitis research during 1984-1993. It was found that the research priority profile was more or less homogenous since majority of the sub-fields are showing either below or above average levels of priority profile. In the first phase of the research period covering from 1984-1993, there are high priorities in 10 sub-fields in USA followed by 9 in UK and 8 in Germany, 7 each in Canada, Russia and Netherlands. On the other hand, in the second phase (1994-2003) there are high priorities for 10 sub-fields in Germany, 9 in UK, 8 in USA, 7 each in Canada, Russia and Netherlands. In the productivity of Pediatrics sub-field, India is in the third position.

  • I. Assumption: Mo-kam-ju, Koelreuteria paniculata is a woody plant mainly cistributed over Northern China. Its sporadic growth along the beaches of Korea and Japan is assumed to have been sowed by the seeds transported adrift on the current across the ocean. II. Use and Growth of the Plant: In China, this plant has been cultivated from early times mainly at temples, it seeds being used as rosaries, its flowers for yellow dyes and medicine for the eyes, and its leaves for black dyes. In Korea and Japan, these plants have been cultivated at temples and used as the material for rosaries. No natural growth of these plants was reported until 1919. III. Discoveries: In this domestic area, Dr. Chung Tae Hyun discovered the plant on the beach between Cho-Do and Chang-san-kot, Hwang-Hae Prov. in 1920. The reporter discovered them on the beach at Buk-Ni, Duk-jok-Do in 1948, at An-Hung in 1956 and on the beach at An-min-Do in 1957. In the Japan area, it was discovered for the first time twenty years ago, mainly along the coast line of the Japan Sea and some along the eastern coast line, at Subo, Yamaguchi Prefecture facing the Pacific Ocean. IV. Study and Experiment: A. Seed The seed coat is thick, non-permeable and floatable. A number of seeds were immersed in artificial sea water and fresh water separately. The seeds remained there for a hundred and forty-five (145) days from April 6, 1957 to August 29, 57. Thirty one seeds out of the fifty immersed in salt water and twenty seeds out of the fifty immersed in fresh water remained on the surface of the water, proving them to be non-permeable to both sea and fresh water. Of course, these had retained their germinating capabilities. Five (5) seeds out of twenty from the fresh water and six (6) out of thirty-one from the sea water were successfully germinated after a hole had been drilled in the seed coat and they had been planted. Thus their floating capability, non-permeability and germinating capability after a possible 145 day trip on the flowing currents has been proved satisfactory according to the assumption made above. B. Current As shown in the Data 2 and 3, the sea current initiated in the Pohai Sea flows westward down along the coast line of Korea reaching the southern part during the autumn and winter seasons. This fact also is in favor of the reporter's assumption. V. Discussion and Conclusion: The reporter concludes that, as discussed above, Koelreuteria paniculata which originates in Northern China is transported adrift on the flowing sea current to our western coast line, and also the coast lines of Shantung and Kuangtung of China and it is germinated on the sandy beaches forming new plants. Thus, the seeds drifted down on the southern beach of Korea and have been transported to the Japanese coast, adrift on the Tae-Ma current. Upon fruition, the seeds of the plants which settle on the coasts of western Korea and Japan will migrate to new places. It can be, however, assumed that while the thickness and nonpermeability of the coat enables the long travel in the water, this also can compose a difficulty in germination, consequently in developing a new distribution of this species.

  • We analyzed 57 types of herbal medicines for Soeumin, clinically applied in Dongyisoosebowon. In order co discover the standard of herbal classification for the Sasang Constitutions, four concepts of Sasang Medicine were applied. These included 'Sadangron (theory of four groups)', 'Seungganggaehap(ascending-descending and gathering-dispersing)', 'Pyorihanyoul(exterior-interior and hot-cold)', and 'Hyungchiaekmi(fragrance, smell, bodily fluid and taste)'. According to these analyzing methods of herbal properties, we have reached the following conclusions: 1. Lee Je-ma first established the physiology of the internal organs of the Sasang Constitutions through the understanding of constitutional pathology. Dr. Lee then classified herbal medicines into four constitutional groups by observing the herbal effects according to such perspective of organ physiology and pathology. 2. Among the Sasang concepts applied in the analysis of herbal properties based on the physiology and pathology of Sasang constitutions, 'Seungganggaehap (ascending-descending and gathering-dispersing)' was found to be the most useful. Meanwhile, 'Sadangron, (the theory of four groups - Spirit, Qi, Blood and Essence),' along with 'Pyorihanyoul (exterior-interior and hot-cold)' and 'Hyungchiaekmi (fragrance, smell, bodily fluid and taste)' were partially useful. 3. Herbal medicines for Soeumin are characterized by ascending energetics that protect the Yang Qi. The 'Exterior heat disease' is treated with herbal medicines that raise the "Exterior Yang" in three different way: by tonifying Qi. by tonifying Blood and by releasing exterior. The 'Interior cold disease' is treated with herbal medicines that descend "Interior Yin" in two ways. One by warming the stomach, and the other by regulating Qi. 4. Cases where a whole category of herbs with the same effect have been applied co one constitution, are most frequent among Shaoyin herbs. There was an intimate connection between the treatment methods and the traditional effects of herbs for 'Soewnin'. These discoveries allowed us to see that the development of the pharmacology of the Sasang Constitutional pathology more progressed in 'Soeumin'. *analysing simple herbs of "DongEuiBoGam JangBu" we compare JangBu of traditional oriental medicine with JangBu of Sasang Constitutional Medicine. So we can comprehend the JangBu's difference of traditional-oriental with sasang-constitional medicine.

  • Background: Synergistic antitumor effects of the combined chemoimmunotherapy based on dendritic cells have been reported recently. The aim of this study is to search new applicability of gefitinib into the combination treatment through the confirmation of gefitinib effects on the monocyte derived dendritic cells (moDCs); most potent antigen presenting cell (APC). Methods: Immature and mature monocyte-derived dendritic cell (im, mMoDC)s were generated from peripheral blood monocyte (PBMC) in Opti-MEM culture medium supplemented with IL-4, GM-CSF and cocktail, consisting of TNF-${\alpha}$ (10 ng/mL), IL-$1{\beta}$ (10 ng/mL), IL-6 (1,000 U/mL) and $PGE_2$ ($1{\mu}/mL$). Various concentrations of gefitinib also added on day 6 to see the influence on immature and mature MoDCs. Immunophenotyping of DCs under the gefitinib was performed by using monoclonal antibodies (CD14, CD80, CD83, CD86, HLA-ABC, HLA-DR). Supernatant IL-12 production and apoptosis of DCs was evaluated. And MLR assay with $[^3H]$-thymidine uptake assay was done. Results: Expression of CD83, MHC I were decreased in mMoDCs and MHC I was decreased in imMoDCs under gefitinib. IL-12 production from mMoDCs was decreased under $10{\mu}M$ of gefitinib sinificantly. Differences of T cell proliferation capacity were not observed in each concentration of geftinib. Conclusion: In spite of decreased expressions of some dendritic cell surface molecules and IL-12 production under $10{\mu}M$ of gefitinib, significant negative influences of gefitinib in antigen presenting capacity and T cell stimulation were not observed.

  • In the present study, we investigated the role of binding immunoglobulin protein/glucose-regulated protein, 78-kDa (BIP/GRP78)-regulated endoplasmic reticulum (ER)-stress on meiotic maturation and cumulus cells expansion in porcine cumulus-oocyte complexes (COCs). Previously, it has been demonstrated that unfolded protein response (UPR)-related genes, such as molecules involved in ER-stress defense mechanisms, were expressed in matured oocytes and cumulus cells during in vitro maturation (IVM) of porcine oocytes. However, BIP/GRP78-mediated regulation of ER stress in porcine oocytes has not been reported. Firstly, we observed the effects of knockdown of BIP/GRP78 (an UPR initiation marker) using porcine-specific siRNAs (#909, #693, and #1570) on oocyte maturation. Among all siRNAs, siRNA #693 significantly reduced the protein levels of UPR marker proteins (BIP/GRP78, ATF4, and P90ATF6) in porcine COCs observed by Western blotting and immunofluorescence analysis. We also observed that the reduction of BIP/GRP78 levels by siRNA#693 significantly inhibited the meiotic maturation of oocytes (siRNA #693: $32.5{\pm}10.1%$ vs control: $77.8{\pm}5.3%$). In addition, we also checked the effect of ER-stress inhibitors, tauroursodeoxycholic acid (TUDCA, $200{\mu}M$) and melatonin ($0.1{\mu}M$), in BIP/GRP78-knockdown oocytes. TUDCA and melatonin treatment could restore the expression levels of ER-stress marker proteins (BIP/GRP78, $p-eIF2{\alpha}$, $eIF2{\alpha}$, ATF4, and P90ATF6) in siRNA #693-transfected matured COCs. In conclusion, these results demonstrated that BIP/GRP78-mediated regulation of UPR signaling and ER stress plays an important role in in vitro maturation of porcine oocytes.

  • In an attempt to teace trands in fashion journalism based on the examination of recent fashion magazines in korea, this study has dealt with the followings: the number of articles on fashion, image of fashion, characteristics of articles, change in "coordinate" and titles, and length of time of publication. The results of this study follow: 1. Among the general magazines for ladies whose titles have been changed, those dedicated to the "Ms class" have increased the pages on fashion and coverage of casual brand: those for housewives have shown no change in contents despite the change in titles, 2. The length of time of publication does not affect the change in the number of articles on fashion. General magazines for ladies have shown the greater "coordinate" in articles on fashion. 3. In terms of the contents of articles on fashion, those devoted to fashion and clothing are specialized and innovation-oriented, whereas general magaines stress the provision of more practical information. 4. The emergence of the X-generation and the newer generation has resulted in positioning of clothing crand, making them chief tarhet readers.ing them chief tarhet readers.

  • From the part "歷代醫學姓氏(Historic Doctors)" in "醫林撮要(Uirimchualyo)", the following has been noticed and concluded. 1. Because acupuncture was originated from stony needle, the word "石(sok)" contains the meaning of needle, and from this point on, words like 石(sok), 砭石(pyumsok), 箴石(Jamsok), 鑱石(Chamsok) had been derived. 2. The word 砭石(pyumsok) used in "Hwangjenaekyong(Yellow Emperor's Canon of Medicine or Hwangdineijing)" should be interpreted as acupuncture in a verb form, not a noun form. 3. 鑱石(Chamsok) or 鑱鍼(Chamchim) was used for surgical treatment for tumor, by cutting open tumors and pressing the pus out. Therefore, 砭石(pyumsok), 鑱石(Chamsok) are the same kind of needles, and 鑱鍼(Chamchim) is the tool improved from 鑱石(Chamsok) used in the Bronze Age. 4. Kwakpak put a note on 鑱石(Chamsok) in "山海經(Sanhaekyong)" that reads "it is defined as 砥鍼(Jichim) and treats tumor." This let us know the shape of 石(sok), 砭石(pyumsok), 鑱(Chamsok), 鑱鍼(Chamchim), and the stone that can be used as a surgical tool with slim & sharp shape is obsidian. 5. Because obsidian is only found around Mt. Baekdu and limited area in South Korea & Japan in Asia, it is closely related with the life & medical environment of the tribe "Mt. Baekdu". 6. The development of 鑱鍼(Chamchim) was influenced by surgical treatment used in early stage of civilization, and its origin is traced upto Gochosun dynasty. Korea's own traditional medical knowledge is derived from this surgical treatment skill. 7. Because the acupuncture is originated from Gochosun dynasty, 鍼(chim) was derived from 箴(Jam) of 箴石(Jamsok), 䥠(Chim) & 䥠(Chim) both were used for a time being, and finally settled into 鍼(Chim). 8. The word 針(Chim) showed up at Myung dynasty, and started to be used in Korea from early Chosun dynasty. 9. In the early Chosun dynasty, 鍼(Chim) was used for medical term, and 針(Chim) for non-medical term. In the mid Chosun dynasty, 針(Chim) was used as a term for tool, and 鍼(Chim) as a term for acupunctural medical treatment. 10. Under the order of King Sunjo, Dr. Yesoo Yang published "醫林撮要(Uirimchualyo)", added "醫林撮要續集(Sequel to Uirimchualyo)", and added "歷代醫學姓氏(Historic Doctors)" again which eventually made totally 13 books of "醫林撮要(Uirimchualyo)". In addition, many parts of "醫林撮要續集(Sequel to Uirimchualyo)" were quoted in "東醫寶鑑(Donguibogam)", and influenced much in publishing "Donguibogam". 11. In "歷代醫學姓氏(Historic Doctors)" of "醫林撮要(Uirimchualyo)", the same way in "Donguibogam", referred to 針(Chim) as a term for a needle, and 鍼(Chim) as a term for Acupuncture. 12. From the usage of 針(Chim) & 鍼(Chim), shown in "鄕藥集成方(Hyangyakjipsungbang)", "醫林撮要(Uirimchualyo)" and "東醫寶鑑(Donguibogam)", we can notice the spirit of doctors who tried to take over the legitimacy of Korean tradition, and their elaboration & historical view that expresses confidence on our own medical technology, through the wording 鍼(Chim).

  • To verify the newly developed decision assisting expert system for nitrogen fertilizer application NES to Illinois cornfields, a couple of N rate studies from Dr. Howard and five Illinois Agricultural Experiment Stations were applied. Four types of recommendations including the current Illinois recommendation, Hoeft recommendation, NES, and maximum economic recommendation were compared with each other for the crop yields, profits, recovery rate, and N losses to cornfields. The N rate of NES recommendation, considering productivity index (PI), soil organic matter content (SOM), and pre-sidedressing nitrate concentration (PSNT) level, was the lowest in comparison to those of other recommendations. However, N recovery rate in NES was generally higher and the resulting N loss was lower than others. But, adherence to the recommendations may also reduce farmers income if environmental expense did not considered. Therefore, NES will be more effective by adding the factors including environmental expense, tillage systems, crop rotation, and other agricultural management parameters.
