Background/Aims: Rectal carcinoid tumors can be resected with endoscopy, and it is important to assess their prognostic factors. We evaluated the potential of Ki-67 expression as a prognostic factor in rectal carcinoid tumors. Methods: We retrospectively reviewed the medical records of 37 patients with rectal carcinoid tumors who got endoscopic resection from January 2001 to January 2011 at Inje University Seoul Paik Hospital. We analyzed their endoscopic and histologic findings, Ki-67 expression, clinical outcome, and prognosis. Results: The mean age (±SD) of the patients was 56.3±10.7 years, and the male : female ratio was 3.6:1. The mean tumor size was 0.5±0.4 cm, 33 patients showed grade 1 tumors (89.2%) and the average Ki-67 expression was 0.7±1.2%. Thirty five patients underwent endoscopic mucosal resection, and two required endoscopic submucosal dissection. Eight patients had positive margins after resection, but no cases of lymphovascular invasion were identified. The median follow-up duration was 21.4±25.4 months, and no recurrences were observed. Conclusions: In low grade rectal carcinoid tumors which are lack of central depression on colonoscopy, the expression of a molecular marker of malignant potential, Ki-67, was low. Therefore, endoscopic resection seemed to be a safe and effective treatment for these tumors.
The objectives of this study were to investigate the perceptions of Korean female university students for clothing pattern tendency and structural element of clothing pattern image dimension and to find how individual personality type influence the preferred clothing pattern characteristics. For this study, a questionnaire was designed and sent to 600 female university students of Daejeon, Seoul and metropolitan area. The tool used in this study was MBTI(The Myers-Briggs Type Indicator) Form G Korean version and for the analysis of data SPSS 10.0 package were used. 10 representative patterns for this study were floral, dot, stripe, check, animal, abstract & artistic, geometric, vegetable & leaf, paisely, patchwork pattern. The data were analyzed by factor analysis, arithmetic mean, One-Way ANOVA, χ^(2)-test. The major findings were as follows: Clothing pattern image dimension perceived by Korean female university students for 10 representative patterns were basic form, deluxe, specialty, and cultral dimension. Among them, basic form and deluxe dimension were major dimensions. In basic form dimension, dot pattern score was high indicating female students perceive it as light, comfortable, clean, cool and simple pattern image. In deluxe dimension, floral pattern scored high and in specialty dimension, abstract and artistic pattern scored high among other pattern image. In cultural dimension, geometric pattern and check pattern scored high. Based on other detailed analysis results, It is concluded that the personality type greatly influence clothing pattern evaluation. For example, in case of color combination of patchwork pattern, there was a difference in color preference depend on a personality type such as sensing(S) or intuition(N). Therefore, sensing personality type preferred adjacent color combination than contrast color combination. Detailed marketing strategy is necessary in planning textile design of merchandise plan.
Background: Most cases of Graves' disease have been treated by antithyroid drugs in Korea. The major drawbacks of antithyroid drugs are the relative high rate of relapse and the inconvinience of long term therapy. Measurement of TBII and TRH stimulation test have been considered as the most reliable tests predicting relapse, but the predictive power is not high enough to use in clinical situation. This study was performed to find good prognostic indicators in Graves' disease patients after the discontinuation of antithyroid drug therapy. Subjects and methods : We restrospectively evaluated 96 patients with Graves' disease who showed normal TRH test at the end of antithyroid drug therapy and were followed for more than one year. Serum T3, T4, T3/T4 ratio, TBII, Anti-TPO Ab and TGAb levels were measured at the time of diagnosis and at the end of therapy. Two to three months after withdrawal of antithyroid medication, serum TSH and free T3 responses to TRH were examined. These parameters were compared between the relapse group and the remission group. Results : Among the 96 patients, 22 patients(22.9%) relapsed(Group Ⅱ) and 74 patients(77.1%) remained in remmision(Group Ⅰ). No significant difference was observed between the relapse and the remission group in clinical parameters, serum T3, T4, TSH, T3/T4 ratio, TBⅡ and Anti-TPO Ab determined before and after treatment. Serum TSH and free T3 levels measured after TRH stimulation were also similar in both groups. Serum TGAb levels determined at the end of treatment were significantly higher in the remission group(p<0.05). Relapse following the discontinuation of therapy occured within 24 months in 72.7% of the relapsed cases. After 24 months, relapse rate was reduced significantly. Conclusion : These results suggest that high serum TGAb levels could be a favorable prognostic indicator for the long term remission of Graves' disease treated with antithyroid drugs, and may suggest that Hashimoto's thyroiditis is combined with Graves' disease in those patients.
주암호의 수직 수평적 수온 구조의 계절변화를 이해하기 위하여, 2000년 3월부터, 2001년 5월까지 수온을 관측하였다. 관측된 수온자료와 기상자료를 이용하여, 수온 변화에 직접적인 영향을 미치는 열수지를 정량적으로 계산하였다. 겨울에는 호수가 대기로 열을 빼앗겼는데, 12월에 최대 109.45W/㎡의 열을 잃었다. 표층수의 냉각으로 대류가 일어나, 수직적으로 균일한 수온을 보였다. 수평적으로는 수온의 차이를 보여, 호수로 물이 유입되는 상류 쪽은 수온 3℃, 댐 부근에서는 약 5℃의 물이 존재했다. 봄이 되면서 주로 표층을 통해 얻는 열로 인해 표층 수온이 상승하여, 수직적인 온도 차이를 보였다. 여름에는 표층을 통해 유입되는 열의 양이 증가하여, 7월에 최매 101.95W/㎡였다. 표층 가열과 함께, 상류로부터 크게 증가한 유량으로 인해 주암호 내부의 열이 증가하여 8월에는 표층 수온이 최대 29℃ 이상이 되었다. 그러나 저층수는 약 7℃였다. 가을이 되면서 표층을 통해 열을 잃게 되어 표층수의 수온이 낮아졌고, 표면혼합층은 두꺼워졌다. 기온이 더 낮아지는 겨울에는 표층을 통한 열 손실이 더 증가하여 2월에 수온이 가장 낮아졌고, 수직적으로 균일한 수온 특성을 보였다. 이러한 수온구조는 3월까지 지속되었다. Temperature profiles were observed to understand seasonal variation of thermal structures in the Juam reservoir from March 2000 to May 2001. Heat flux which affects thermal structures was calculated by observed water temperature and meteorological data. temperature became homogeneous vertically by convection due to the surface cooling in winter. Maximum heat loss through the surface (109.45 W/m²) occurred in December. There was a horizontal gradient of water temperature in winter. The temperature was 3℃ at upstream and 5℃ near the dam. The surface temperature increased by the increase of solar radiation in spring and summer. Maximum heat gained through the surface was 101.95W/m² in July. Maximum surface temperature was 29℃ in August, whereas the bottom water was 7℃. Surface mixed layer became thicker and its temperature decreased by surface heat loss in fall and winter.
Objectives and Method : To find the change of clinical laboratory value change of some chronic degenerative disease patients who were admitted to E sanatorium hospital in Y city from January 2001 to June 2002 after a health promotion program, a quasi-experimental study was done. Results : 1. The characteristics of study subjects showed 47.5% of male, 52.5% of female, 50% under 50 years in age Their common disease was cancer and cardiovascular disease, endocrine disease, liver disease followed in frequency. Before admission 74.2% smoked, 67.5% enjoyed drinking alcohol and 92.5% preferred to take meat 2. After health promotion program mean systolic blood pressure, diastolic blood pressure, serum total cholesterol, serum triglyceride, fasting blood sugar and serum total protein were decreased statistically significantly, compared to the value at the beginning of admission 3. By the group of patients characteristics like sex, age, smoking status, drinking status, meat intake preference and kind of diseases suffering from, mean systolic blood pressure, diastolic blood pressure, serum total cholesterol, serum triglyceride showed consistent decrease after health promotion program compared to the beginning of admission Mean levels of fasting blood sugar, serum total protein, white blood cell (WBC) counts, red blood cell (RBC) counts, GPT showed irregular change in some patients characteristics group Conclusion : Keen and consistent change was shown at blood pressure and lipid parameter after a health promotion program toward chronic degenerative disease patients. To confirm that the cause of change was due to life style change or accidental reason, further systematic studies are required.
This study was done to present a criterion in selection of the most proper light sources and materials by measuring metamerism index(MI) of the light curing composite resins with spectrocolorimeter. Metamerism is defined when two objects appear to be the same color in one illuminant but different in another. This is due to the fact that they have different spectral curves that fail to match under the second illuminant. In this study, A1 & A3 shade of five light curing composite resins (Esthet-X, Filteck Z250, Filteck A110. Charisma. Vitalescence) were chosen based on Vita shade. Five samples were made for shade of each product with Teflon mold (diameter: 15mm, thickness: 2mm). Metamerism index of each samples on a Barium sulfate plate(L^(*)=96.54, a^(*)=0.19, b^(*)=0.01) prepared for sample fixation were measured with spectrocolorimeter(Miniscan XE plus. Model 4000s. Hunter Lab. USA) by applying standard light source D_(65), C. Fcw, TL84 and A. Standardization was done with reference standard(X=80.8, Y=85.7, Z=90.8) and light trap. The results were as follows. 1. Different resins with same Vita shade showed recognizable color difference (ΔE^(*)>2). 2. All composites had MI below accepted value 0.5 between standard illuminant(D_(65), C, & A) and below 1.5 under fluorescent condition (Fcw & TL84). 3. MI value between D_(65) and A showed higher value than MI value between other source of light(p<0.01). 4. All resins except Z250 showed MI value that A3 is higher than A1 between D_(65) and A(p<0.05).
There were problems in selecting exact colors of composite resins currently used in clinic by examining with naked eyes. This study was done to present a criterion in selection of the most proper light sources and materials by measuring metamerism index of the light curing composite resins with spectrocolorimeter. Metamerism is present when two objects appear to be the same color in one illuminant but different in another. This is due to the fact that they have different spectral curves that fail to match under the second illuminant. In this study, five light polymerized composite resins; Esthet-X, Filteck Z250, Filteck A110, Charisma, Vitalescence which are currently used in clinic were chosen based on Vita shade. Five samples were made for shade of each product with Teflon mold(diameter: 15mm, thickness: 2mm). Compressed resins with glass slab were light polymerized with a visible light curing unit(Optilux 500, 13mm tip diameter, Demetron, USA) for 60 seconds. Polymerized samples were removed and those were grinded to 2.0mm in thickness with sand papers(#600 & #1000). Samples were carefully prepared without fingerprints and impurities in grinding procedure and kept in distilled water for a week at room temperature. Metamerism index of each samples on a Barium sulfate plate(L^(*)=96.54, a^(*)=0.19, b^(*)=0.01) prepared for sample fixation were measured with spectrocolorimeter(Miniscan XE plus. Model 4000s. Hunter Lab, USA) by applying standard light source D65, C, Fcw, TL84' and A. Standardization was done with Reference standard(X=80.8, Y=85.7, Z=90.8) and Light trap. Samples were kept in distilled water at room temperature in all procedures. The results are as follows. 1. Different resins using same Vita shade showed recognizable color difference(ΔE^(*)>2). 2. All composites had Ml below accepted value 0.5 between standard illuminant(D65, C, & A) and below 1.5 under fluorescent condition (Fcw & TL84). 3. Ml value between D65 and A showed higher value than Ml value between other source of light(p<0.01). 4. All resins except Z25O showed Ml value that A3 is higher than Al between D65 and A(p<0.05).

The purpose of this study was to investigate smoking status of high school students, and the effect of smoking on school life attitudes. A total of 370 male students in Jinchun-kun were asked to complete a self-administered questionnaire, and the data of 355 students were analyzed. Thirty-seven percents of the respondents smoked. Among the smokers, 34% started smoking from the first year of high school and 26% from the third year of middle school. Fifty eight percents of the smokers started smoking due to curiosity, and 21% for relaxing from stress. Smokers spent more money than non-smokers. More smokers were dissatisfied with school life, made poor academic achievements, and had girl friends compared to non-smokers. These results indicate that a smoking student had several undesirable characteristics as a student. Therefore, education for the effects of smoking should be offered to high school students and even to middle school students in order not to start smoking as well as to abstain from smoking.
We investigated that the effects of residential type on energy balance in college students. Total sixteen college students were participated in this study, all subjects were assigned one of three groups: either school attendee students group, self-governed living students group, dormitory students group. Routine physical activity level (for 5 days including three weekday and two weekend) and food intake were surveyed. For investigation of degree of physical activity, all subjects were requested to record on their physical movements as possible as detail should be obtained. To all subjects, five-day dietary log form was given, and used for examining of calorie intake from their routine diet. There was no statistical difference in energy intake and consumption in each. However energy consumption was significantly higher than energy uptake in school attendee students group. All other groups were shown a similar energy values between energy uptake and consumption. There were no significant differences in energy intake and consumption in any of experimental groups when comparisons were made between weekdays and weekend. As far as energy uptake was concerned it was no statistical difference in any of major nutrients among groups. In conclusion, partial imbalance was found between energy intake and uptake in school attendee groups. This may be due to their more active life style than other groups'. In future studies, better controlled study should be performed not only more subjects are recruited but also minor nutrients are included for examining of energy balance.
