Objectives : There is a increasing need to recruit and retain more psychiatrists who can plan and implement organized programs to work with chronic mentally ill patients in community settings. The aim of study is to discover what training is currently in place to prepare psychiatrist for work in "community" or "public" settings. Methods : Survey questionnaires were mailed to 85 residency training directors and 10 leaders of community mental health in 2005. Response rate was 75%. Results : Academic seminar about community mental health were not administered to residents in 63% of training hospitals. Forty one out of 64 training hospitals had community mental health rotation programs, Community mental health center (50%) and day hospital (36%) were the most common type of programs. Few general hospital had affiliation with community mental health programs. The amount of time for clinical rotation varied from less than three months part time to 6 months fulltime, with most frequent form of one day per week for three month in second or third year of psychiatry residents. Conclusion : Further steps are needed to improve residency training curricula and to encourage well qualified psychiatrist to choose careers in community psychiatry.

Background/Aims: To prevent hypocalcemia after parathyroidectomy (PTX), parenteral calcium is required in addition to oral calcitriol and calcium. After switching to oral calcium, patients can be discharged from the hospital. The aim of this study was to analyze the clinical characteristics and outcomes of PTX performed at a single Korean center and to investigate the associated laboratory factors used to analyze the total amount of postoperative calcium required. Methods: We enrolled 91 hemodialysis patients undergoing PTX from November 2003 to December 2011. We collected clinical and laboratory data preoperatively, 12 and 48 hours postoperatively, at discharge, and 3 and 6 months postoperatively. Results: In total, 59 patients underwent PTX with autotransplantation (AT), 6 underwent total PTX without AT, 11 underwent subtotal PTX, and 15 underwent limited PTX. Total PTX without AT showed the lowest recurrence rate. At all postoperative time points, the mean levels of serum calcium, phosphorus, and intact parathyroid hormone (iPTH) decreased significantly, compared with preoperative levels; however, alkaline phosphatase (ALP) increased significantly from 48 hours postoperatively to discharge (p < 0.001). On multiple linear regression analysis, the total amount of injected calcium during hospitalization showed a significant correlation with preoperative ALP (p < 0.001), preoperative iPTH (p = 0.037), and Δphosphorus at 48 hours (p < 0.001). We developed an equation for estimating the total calcium requirement after PTX. Conclusions: Preoperative ALP, preoperative iPTH, and Δphosphorus at 48 hours may be significant factors in estimating the postoperative calcium requirement. The formula for postoperative calcium requirement after PTX may help to predict the duration of postoperative hospitalization.

칠절봉 신갈나무림의 군락구조와 토양환경과의 관계를 파악하기 위해 식물사회학적 조사와 토양 환경을 분석하였다. 조사지역의 신갈나무림은 신갈나무군락, 철쭉꽃하위군, 큰개별꽃하위군으로 구분되었으며, 철쭉꽃하위군과 큰개별꽃하위군에서의 방형구당 평균출현종수는 각각 30종(24∼46종), 43종(31∼52종) 이었다. 피복지수치에 의한 계층별 우점순위는 교목층에서 신갈나무(6750.0), 아교목층에서 당단풍(2364.0) 관목층에서 철쭉꽃(988.5), 초본층에서 쌀새(1040.5)가 가장 높게 나타났다. 신갈 나무림의 DBH 분포는 2∼10㎝ 범위의 소경목이 전체의 29.7%를 차지하였으며 전체적으로 정규분포를 나타내어 교란 후 재생과정에 있는 것으로 조사되었다. 또한 후계목의 발달로 인한 극상상태로의 천이가 가능할 것으로 조사되었다. 전반적인 토양환경은 두 하위군 간에 뚜렷한 차이가 없었으며, 큰개별꽃하위군이 철쭉꽃하위군에 비하여 다소 양호한 것으로 조사되었다. 환경구배분석에서 까치박달, 물푸레나무, 함박꽃나무 등은 습한 곳에 분포하고 철쭉꽃, 전나무, 국수나무 등은 건조한 곳에 분포하는 것으로 나타났다. A relationship between the community structure composition and soil environmental factors of the Quercus mongolica forest on Mt. Chiljelbong was investigated from June 1996 to August 1997. The Q. mongolica community was classified into two subcommunity of Rhododendron schlippenbachii and Pseudostellaria palibiniana. The 30(24-46) species per quadrat were appeared in R. schlippenbachii subcommunity and 43(31-52)species in P. palibiniana subcommunity. The dominant sequences on each stratum determined by the coverage index showed that Q. mongolica was the most dominant in tree-1 layer with 6750.0, Acer pseudo-sieboldianum in tree-2 layer with 2364.0, R. schlippenbachii in shrub layer with 988.5, and Melica onoei in herb layer with 1040.5 value. The value of diameter breast height(DBH) showed a normal distribution displaying a highest value in the range of 2∼10㎝(29.7%) in Q. mongolica forest and it was investigated being at restoration phase after disturbance. It also was investigated that the succession to climax state would be possible due to growth of successive tree. Overall, which the soil conditions make little difference between two subcommunities, P. palibiniana subcommunity was favorable than those of R. schlippenbachii subcommunity. It was shown that in an environmental gradient analysis, Carpinus cordata, Fraxinus rhynchophylla, and Magnolia sieboldii were distributed in a mesic area, but R. schlippenbachii, Abies holophylla, and Stepanandra incisa in a xeric area.

Polymerase chain reaction (PCR) is the most sensitive and rapid method for the diagnosis of M.tuberculosis infection. Many reports have shown different methods for mycobacterial DNA extraction, but revealed many differences in simplicity and time-consumption. We studied which method was the best among 7 different ones for DNA extraction from 32 smear-positive sputa, using PCR of targeting 123bp DNA fragment of IS6110. The methods were the following : SDS-Microwave oven method, NaOH Lysis method, Triton X-100, Proteinase K method, Lysis buffer method. SDS-Proteinase K method, Bead Beater method, and Bead Beater/CTAB method. The amplification products were identified by electrophoresis on ethidium bromide-stained agarose gels, and confirmed by restriction enzyme, Southern blot hybridization, and DNA sequencing. All 32 cases were positive (100%) by the 7 different methods. It took 1 hour or more to detect DNA in SDS-Microwave oven method, NaOH Lysis method, and Bead beater/CTAB method. It took 2 hours or less in the others. SDS-Proteinase K method and Bead Beater/CTAB method were simpler and more convinient than the others. These results suggest that SDS-Proteinase K method and Bead Beater/CTAB method might be better than the others for the extraction of mycobacterial DNA in terms of simplicity and time-consumption, although all the methods were sensitive.

The purpose of this study is to set up the new vision for a view of housework of women. To fulfil the purpose, 1 looked into the contents of the women's view of housework through "Nae-Hoon", "Gye-Joong. Yo-Ram", "Gye-Nyeo-Syeo", "Sasojeul" "Kyu-Hap-Chong-Syeo", "So-hak", "Yeo-Sa-Syeo", etc. And I investigated the contents of women's housework-food. clothing housing. The characteristics of the view of housework centering on the norm of CHosen-Dynastyare as follows. 1. Women should learn how to cook and make clothes. 2. Housework is related to filial duty to parents-in-law 3. The basic attitude toward to housework was devotion and cleanliness 4. Women have to do housework for the season. It is acclimate herself to environment 5. Housework-performing an ancestral rites is emphasized ancestor worship. 6. Women's housework in the early times of Chosun-Dynasty put its emphasis on benevolence ideal norm. however in late it was changed into housework as practical norm.

Spin-Peierls 전이를 하는 CuGeO₃계에 원소를 치환했을 때의 자기적 및 결정학적 특성을 비교 검토하고, 직접 Cu₁-xGe₁-xFe₂O₃(x=0.05, 0.1) 시료를 제조하여 SQUID, Mssbauer 분광기, X-선 회절 방법으로 연구하였다. 이 시료의 결정구조는 orthorhombic 이고 격자 상수는 x= 0.05 때 a = 4.795Å, b=8.472Å, c=2.904Å 이고 x=0.1때는 a=4.784Å, b=8.472Å, c=2.904Å였다. 상온에서 Mssbauer 스펙트럼은 Fe³+ 이온의 사면체 자리에 의한 이중선과 팔면체 자리에 의한 Zeeman 선으로 중첩되어 나타났고 자기감수율의 극대점과 Mssbauer 변수의 불연속으로부터 본 시료의 spin-Peierls 전이 온도는 13K 임을 알아냈다. The magnetic and crystallograpic properties of the substituted spin-Peierls transition CuGeO₃ system have been reviewed, and we synthesized the Cu₁-xGe₁-xFe₂xO₃ (x=0.05 and x=0.1) system and studied by superconducting quantum interference device, Mossbauer spectrometer and x-ray diffractometer. The crystal structure is orthorhombic and the lattice constants are decreased as increasing iron contents. That is, in Cu₁-xGe₁-xFe₂xO₃ system a=4.795Å, b=8.472Å and c=2.932Å for x=0.05, and a=4.784Å, b=8.472Å and c=2.904Å for x=0.1 respectively. The Mossbauer spectra are superposition of the doublet due to the Fe³+ ions at tetrahedral sites and the sextet due to the Fe³+ ions at octahedral sites at room temperature. From the cusp of the magnetic susceptibility and the discontinuity of Mossbauer parameters we found the spin-Peierls transition temperature of our samples is 13K.

6주간 고지방식이를 섭취한 흰쥐에 있어 송화분과 탈지 송화분이 혈청과 간장에서의 지방 축적과 대사에 미치는 효과를 관찰하였다. 혈청에서의 total lipid, total cholesterol 농도는 고지방 식이군에 비해서 탈지 송화분과 송화분 투여군이 유의적으로 감소하였다. 혈청에서의 triglyceride 농도는 탈지 송화분과 송화분 투여군이 고지방 식이군과 비교했을 때 뚜렷한 감소를 보였으며, 이는 정상군과 비슷한 농도를 나타내었다. 혈당농도는 송화분, 탈지 송화분 투여군에서 유의성 있게 감소하였다. 간장을 조직학적으로 관찰한 결과, 고지방식이로 인한 조직의 지방 침착은 송화분 투여군에서 다소 억제함을 보였다. 이상의 결과를 미루어 볼 때 송화분은 동맥경화증 및 순환기계 질환의 예방과 치료에 효과적일 것으로 사료된다. Effect of pine pollen and defatted pine pollen on lipid accumulation and metabolism in serum and liver were investigated with rats fed high fat-supplemented diets for 6 weeks. Concentrations of total lipid and total cholesterol in serum significantly decreased in the experimental groups(treated with pine pollen and defatted pine pollen) compared with the control group. Concentration of triglyceride in serum was remarkably lower than that of control group. This was similar to that of normal group. Concentration of glucose in serum was significantly lower in the experimental group. It was observed from photographs of hepatic tissue in rats that pine pollen inhibits the lipid accumulation induced by high fat diets.

재조합 대장균에서 대량발현 시킨 Citrobacter freundii KCTC 2006 유래이 효소 β-tyrosinase를 이용하여 pyrocatechol, sodium pyruvate, ammonium acetate로부터 3,4-dihydroxy phenyl-L-alanine을 생산하기 위한 연구를 수행하였다. 이 효소반응에 적합한 온도 및 pH 조건은 각각 18℃와 8.5로 결정되었고, 반응액 중의 ammonium acetate와 sodium pyruvate의 농도는 각각 300 mM, 50 mM 이상으로 조절하는 것이 적합하였다. Pyrocatechol의 경우는 20 mM에서 가장 높은 반응성을 나타냈으나, 기질을 반복적으로 첨가하며 장시간 동안 효소반응을 수행하는 경우에는 pyrocatechol의 고갈을 피하기 위하여, 20 mM에서 50 mM 사이로 조절하였다. 한편, 반응액 중에 ethanol을 10% 첨가한 경우에는 반응속도가약 20% 증가하였다. 이상과 같은 효소반응특성에 기초하여 조제한 기질용액에 β-tyrosinase를 1 unit/㎖ 농도로 가하고, pyrocatechol과 pyruvate가 고갈되지 않도록 간헐적으로 첨가하면서 효소반응을 수행한 결과, 24시간 만에 85.2%의 수율로 31.6g/ℓ의 3,4-dihydroxyphenyl-L-alanine를 생산할 수 있었다. By using the β-tyrosinase of Citrobacter freundii KCTC2006, which was cloned and overexpressed in Escherichia coli, 3,4-dihydroxy phenyl-L-alanine (L-DOPA) was synthesized efficiently from pyrocatechol, sodium pyruvate, and ammonium acetate. Optimal temperature and pH for the reaction were determined to be about 18℃ and 8.5, respectively. The effects of substrate concentrations were also examined at different concentrations of ammonium acetate, sodium pyruvate, and pyrocatechol. Ammonium acetate and sodium pyruvate increased the reaction rate until the concentrations reached to 300 mM and 50 mM, respectively. Although pyrocatechol showed the optimal concentration at 20 mM, it was controlled between 20 mM and 50 mM to avoid the depletion of substrate during the enzymatic synthesis. Based on above results, a reaction medium for the production of L-DOPA was prepared and incubated with 1 unit/㎖ of β-tyrosinase. Pyrocatechol and sodium pyruvate was added to the reaction solution intermittently to avoid the substrate depletion during the enzymatic reaction. After 24 hour of reaction, 31.6 g/ℓ L-DOPA was accumulated in the reaction solution as soluble and precipitated ones and the conversion yield was about 85.2%.
