The purpose of this study was to examine the effects of treadmill exercise on adolescents serum lipids. This study was a simple pre- and post-test design. The participants of this study were 7 middle-school students located in a metropolitan city, Korea. All participants were boys (mean age=15.81 years; SD=.36), and were treated as a experimental group. A 12-week treadmill exercise program (60 min. & 3 times per week) was implemented. To collect blood samples and analyze TG, TC, HDL-C, and LDL-C, the Becton Dickison Vacutainer System was used. Results revealed that the participants' TG, TC, LDL-C were significantly decreased after the program. However, no significant differences were found in HDL-C even though there was an increase after the program. It was concluded that a 12-week treadmill exercise program can be as effective as other types of aerobic exercise in improving adolescents' serum lipids. Recommendations for future research and practice were provided.

The experiment was carried out to establish of labor-saving control system on paddy field transplanted young rice seedling by machine. We examined the effect of control value between conventional control method that applied 6 times to paddy field during cultivation period and labor-saving control method that applied systematic pesticide one time to the seed, to the nursery box at transplanting day and twice to the middle stage of rice cultivation. The control value in labor-saving control method of Laodelphax striatellus, Nephotettix cincticeps and Lissorhoptrus oryzophilus were 93.4%, 92.7% and 86.1% compared with untreatment field, respectively and also the labor-saving method was more efficient than conventional control method at early stage of rice cultivation. The control value in labor-saving method of Nilaparvata lugens, Sogatella furcifera, Cnaphalocrocis medinalis were more than 84% and these showed almost same trend with conventional control method. The control value in labor-saving method of leaf blast and panicle blast were 91.7%, 93.8%, that showed similar result with conventional control method. The control value in the nursery box at transplanting day of sheath blight was 83.6%, these result were better than conventional control method that applied 2 times at middle stage of rice cultivation.

We analysed 404 patients with primary lung carcinoma who were treated at Soonchunhyang University Hospital from July, 1985 to september, 1993 in order to investigate the survival rate and epidemiolgical properties of primary lung cancer. They were 330 males and 74 females. The most prevalent decade was seventh. In terms of cell type, the squamous cell was 225 patients (55%), and adenocarcinoma, small cell, mixed type was 21%, 19%, 4%, respectively. Among non-small cell lung carcinoma, stage Ⅲa was the most prevalent one(92%). In case of small cell carcinoma, the limited stage was 64%. The 12-, 24-, 36- month survival rate of total patients was 57%, 31%, 22%, respectivley and median sruvival time was 15 months. The 36-month survival rate tended to be longer in non-small cell lung carcinoma than that of small cell lung cancer, but there was no difference between two groups, statistically. In non-small cell carcinoma, The 36-month survival rate and meidan survival time were longer in the stage Ⅰ and Ⅱ than those of Ⅲa, Ⅲb, Ⅳ (80% versus 38%, 22%, 0%, p<0.05). According to involvement of lymph node, the 36-month survival rate was longer in NO and N1 than those of N2, N3 (61.9%, 48.7% versus 17.7%, 17.3%, p<0.05). In small cell carcinoma, The 36-month survival rate and median survival rate were higher and longer in limited stage than those of extensive stage(16.1% and 13 month vs 10% and 8 month, p<0.05). In conclusion, we report here the incidence of primary lung carcinoma and the survival rate of paients with primary lung carcinoma who were treated in Soonchunhyang University Hospital.

The purpose of this study was to evaluate clinical applications of electroplating method through investigation of the physical properties of orthodontic rectangular wires according to varying their cross section. For the study, it was accomplished to electroplate the 0.016-inched orthodontic rectangular stainless steel wire. The cross section of stainless steel orthodontic rectangular wire increased from 0.016 X 0.016 inch to 0.017 X 0.017 inch by electroplating. The wire was heat treated to improve an adhesion between the wire and electroplated metal. A three-point bending test and torsion test were conduced in order to compare physical properties among three wire groups; 0.016 X 0.016 wires(group 016P) and 0.017 X 0.017 wires(group 017). Through the investigations of each wire group, following results were obtained. 1. At three-point bending test, the group 016P showed higher tendency in the degree of stiffness, yield strength and ultimate tensile strength than the group 016. Stiffness and ultimate tensile strength showed statistically significant differences between two groups at three-point bending test(p<0.05). 2. Stiffness, yield strength, and ultimate tensile strength of the group 016P showed lower tendency than those of the group 017. Stiffness showed statistically significant differences between two groups at three-point bending test(p<0.05). 3. Torque/twist rate, yield torsional moment, and ultimate torsional moment of the group 016P showed higher tendency than those of the group 016. All measurements showed statistically significant differences between two groups after torsion test(p<0.05). 4. Torque/twist rate, yield torsional moment, and ultimate torsional moment of the group 016P showed lower tendency than those of the group 017. Yield torsional moment, and ultimate torsional moment showed statistically significant differences between two groups after torsion test(p<0.05). Xylitol is a 5-carbons carbohydrate, which can be replaced with sucrose for preventing caries. The replication of Streptococcus mutans and its formation of artificial plaque were studied in the media containing xylitol. The combined effect of xylitol and other carbohydrates on Streptococcus mutans was also studied. The replication of Streptococcus mutans was inhibited according to the increased concentration of xylitol. Streptococcus mutans replicated at the initial stage of incubation in the media contaning glucose, fructose or lactose, while replication from the beginning of incubation in the media containing fructose as combining with xylitol. The formation of artificial plaque by Streptococcus mutans was significantly reduced in the media containing with xylitol and fructose. These results indicated that the replication of Streptococcus mutans was inhibited according to the increased concentration of xylitol, and the formation of artificial plaque by Streptococcus mutans was significantly inhibited in the media containing xylitol and fructose.

본 연구는 여러 가지 용도에 적합한 생석회를 생산하기 위하여 풍촌 석회석을 대상으로 소성시험을 하였다. 시료의 형상은 주로 정방형이나 때로는 구형을 나타내며, 배색 내지 회백색을 띈다. 소성시험에 사용한 시료의 크기는 45∼50㎜ 이며, 소화시험에서는 3.3mm(6mesh) 이하로 분쇄하여 소성하였다. 시료의 광물학적 특성을 보기위하여 편광현미경 관찰, X-ray 분석, 열분석을 하였다. 시료는 거의 순수한 CaCO₃이었으며, 600℃ 부터 열분해가 시작되어 850℃에서 완결되었다. 화학분석 결과 CaO 98.27%인 잠재적 순도를 갖는 생석회를 얻을 수 있음을 알 수 있다. 대략 50 ㎜ 정도의 석회석은 전기로의 온도가 실온에서 1,050℃에 도달하였을 때 99%이상이 소성되었다. 이 때 얻어진 생석회는 거의 순 백색이며 갈라짐이 없었다. 소화시험 결과 ASTM C-110에 의하면 반응성이 우수한 생석회인 것을 알 수 있으며, 1분 이내의 상승온도는 63℃ 이었다. In this study, the calcination characteristics of Pungchon limestone was investigated to produce the optimum quick lime for various uses. The shape of limestone sample was mainly cubic, but sometimes longish. Approximate size range for the calcination tests was from 45 to 50 mm. For the slaking test, it was crushed by cobbing method and screened by 3.3 mm(6 mesh) screen. Mineralogical studies of the sample were carried out to investigate textures, X-ray diffraction analysis and thermal analysis. The result of chemical analysis shows a very high grade limestone with a CaO potential of 98.27%. Approximate 50 mm size's of limestone, about 250 g was calcined more than 99% when the calcination temperature arrived at 1,050 ℃ from room temperature in the electric laboratory furnace. Lumpy lime in nearly white colour with nearly no cracks was observed during calcining test. and during calcination process the limestone places kept their shape. Slaking test(ASTM C-110 ) results indicate a high reactivity product. In slaking, a 63℃ temperature rise was achieved within the first one minutes.

We performed a variety of lymphocyte stimulation tests, delayed hypersensitivity skin tests, and enumeration of several lymphocyte subpopulations in 21 patients with gastric cancer who did not receive any form of anticancer therapy, and in 20 healthy controls. The gastric cancer patients had significantly decreased number and total score of positive reactions in delayed hypersensitivity skin tests compared with the healthy controls. The percent of CD_(4) positive lymphocytes in the gastric cancer patients was significantly decreased compared to the normal control subjects, but it had no correlation with the total score of delayed cutaneous hypersensitivity reactions. The ratio of helper to suppressor cells was lower in the cancer group. The uptake of 3H-thymidine was markedly depressed in cancer patients when stimulated with various mitogens. There was little correlation between any of the stimulation tests and any of the lymphocyte subpopulation proportions to delayed hypersensitivity cutaneous reactions. Optimal proliferative response was found in lymphocytes stimulated with 10 micrograms of concanavalin-A and 10 microgram of phytohemagglutinin. Advanced stage patients had greatly depressed delayed hypersensitivity skin reactions and proliferative responses to mitogens compared with localized diseases. These results suggest that gastric cancer patients have depressed cellular immune functions, which mainly result from the decreased helper cells and defects in functional proliferative response to mitogens. Interleukin-2 and interferon-gamma restored the in vitro proliferative response of lymphocyte in patients with gastric cancer.

Ntural Science including exercise physiology was stated as a main stream in Keunjong Cho's (1992) and Hanbum Cho's reports (1997) about the trends of gymnastic study and in Chihwan Ji's reports (1997) about Taekwondo study. I agree to the statements that the theses in the field of the natural science like mensuration and physiology are predominant. I anticipate as well that the study in the field of civic science such as sociology, psychology, sports industry and business management will get more activated. In relation to the identification of Taekwondo study, es pointed out by Chihwan Ji et al(1997), rmst frequent subject is the match, and leg-kick, physical strength, dynamics are surely major variants to be issued. But the clarification of the intrinsic mattes are relatively negligent. The identification of Taekwondo study needs to be set up through diverse approach to grade, smash, Taekwon Gym, and trial match. The position of Taekwondo study is expected be promoted along with the increased numbers of published theses (more than 100 p.a. since 2002). The studying environments to achieve a qualitative development in comparison with the quantitative development should be formed to secure the identity of Taekwondo. These efforts get to give an initiative to establish a Korean Society of Taekwondo which Taekwondo personnels have desired for a long time. Building a accurate and broadly comprehensive database system for various kinds of dissertations available at the library of National Assembly should be precedented.

Purpose: The purpose of this study was to understand the degree of depression, sleep quality, job stress and their association among office workers. Method: A self-administered questionnaire was distributed to 147 workers employed in 5 big enterprises, and 5 small and medium enterprises from October 21 to November 21, 2012. The questionnaires included socio-demographic and health-related characteristics, job-related characteristics, sleep quality, job stress (KOSS) and depression (CES-D). Result: Among all subjects, 23.1% was in the depression group (21 points and over in the CES-D score). Depressive level was positively correlated with job stress and quality of sleep. The adjusted odd ratio for the effects of sleep quality and job stress on depression significantly increased in the depression group compared to that of the normal group. Multiple regression analysis revealed that the following factors of influence had combined explanatory powers on depression: BMI, life satisfaction, quality of sleep, and job stress. Conclusion: The study revealed that complicated influences were exerted on the level of depression by variable factors, as well as socio-demographic characteristics, health-related characteristics, quality of sleep, and job stress. Specifically, the level of depression was influenced by the quality of sleep and job stress.
