The experiments were conducted to determine the factors such as light and darkness, phytohormone and seed coat, influencing on seed germination of Bidens tripartita L. and B. frondosa. The seeds of both species were germinated when seed coat was damaged and weakened GA3 and BA stimulated germination of both species but ABA and IAA had no effect on germination of them, which ranged 50.0% to 80.0%. In B. forndosa, when inner layer of seed coat was removed, germination was highly promoted up to 96.7% compared with 10.0% germination rate in another treatments.

Purpose: Only a few studies have explored nationwide trends in lipid profiles among Asian adolescents. We aimed to assess trends in lipid profiles and the associated lifestyle factors among Korean children. Methods: We analyzed data for 2,094 adolescents who were aged 10-18 years and had participated in the Korea National Health and Nutrition Examination Surveys in 1998 and 2010. Results: During 1998-2010, the prevalence of obesity significantly increased in boys, but no changes were observed in girls. Over this period, there was a small but significant decrease in the mean lowdensity lipoprotein (LDL)-cholesterol level in boys (1998, 87.5 mg/dL; 2010, 83.6 mg/dL; P=0.019) and mean triglyceride levels in girls (1998, 90.8 mg/dL; 2010, 85.8 mg/dL; P=0.020). There were no significant changes in the prevalence of dyslipidemia in boys, but a modest decrease was noted in girls (1998, 25.1%; 2010, 18.3%; P=0.052). During the study period, the prevalence of breakfast skipping decreased, whereas that of regular exercise increased in both groups. Daily total energy intake did not change between these years. In multivariable logistic regression analyses, breakfast skipping was associated with increased risk of hyper-LDL-cholesterolemia in boys (odds ratio [OR], 5.77) and hypertriglyceridemia (OR, 2.27) in girls. Regular exercise was associated with decreased risk of hypo-HDL-cholesterolemia (OR, 0.40) in boys. Conclusion: Although the prevalence of obesity in boys increased, favorable or constant trends in lipid profiles were observed among Korean adolescents during 1998-2010. Decrease in breakfast skipping and increase in regular exercise may have contributed to these trends.

Objectives: This study aims to examine if a garbage dumping site has real and negative influence on the quality of life (QOL) for the nearby residents. The net effects of the residential distance from the garbage dumping site and from the garbage truck route were investigated for five domains of the QOL. Methods: Two hundred fifty seven Shin-dong Myeon residents, Chun-cheon Si, participated in a self-administrated survey. The Shin-dong Myeon garbage dumping site began operating in 1996. ANCOV A with generalized linear models and multiple regression analysis were performed. Results: Descriptive analyses show that a residence nearby a garbage dumping site is negatively associated with the physical and environmental domains of the QOL. The residential distance from the garbage truck route does not exert any significant effect on various domains of QOL, except for the environmental domain. On the multivariate analysis, the residents living near the garbage dumping site tended to have a significantly negative QOL in the physical and environmental domains. However, the distance from the garbage truck route did not show a significant nor substantial effect on the QOL. The demographic and socioeconomic control variables are associated with a number of the QOL domains, and their patterns are consistent with the general expectations. Conclusions: The results indicated that a garbage dumping site is considered to be an environmental hazard among the nearby residents according to the lower scores on the physical and environmental domains of the QOL. The findings from this study provide comprehensive understanding on the residents' QOL, and they may help politicians and policy makers make decisions for appropriate interventions.

This study was planned to suggest countermeasure of nutrition education by investigating adolescents, dietary behavior, food weight, and acknowledgement of food calories. 210 middle school boys were selected and asked to fill out the questionnaire. The subjects were divided by nutrition education experience; 1st grade who received nutrition session and 3rd grade who divided subjects. In terms of acknowledgement of food calories subjects nutrition education experience had more recognition for calories than the other group(p<0.01). When one bowl of rice, a potato, a bowel of kimchi and a carrot were asked. However recognition for meats, fishes and eggs were not different between two groups. Among milk and dairy foods the educated group showed high recognition both calories and weight of a piece of cheese than the other(p<0.05). The educated group showed better recognition for calories and weight of tea-spoon of butter, a tea spoon of oil and a tea-spoon of mayonaise, compared to the other group(p<0.01, p<0.05, p<0.05). Also the educated group showed better recognition for calories and weight of a packet of shrimp snack than the other group. The results of this study suggest that nutrition education improved the recognition of calories and weights of foods in study subjects. Also, the number of foods recognized for their calories and weights was higher among subjects who received nutrition education. These results will influence the choice the food by adolescents. Also the nutrition education are thought to be more effective by using photographs or food models, not just by lectures on theories.

Although many operative techniques have been developed to approach the parotid a gland, high recurrence rate and the occurrence of facial palsy still remain to be dilema in the parotidectomy. After reviewing 179 cases of parotid tumor retrospectively, including 8cases which utilized the peripheral approach, the authors came to the following conclusions. 1) The sex ratio is 1 : 1 and the mean age of occurrance was 43.1 for benign tumors and 43.4 for malignant tumors. 2) The histopathologic findings showed that 155 cases were benign tumors(86.5%)and 24 cases were malignant tumors(13.5%) 3) Among the benign tumors, the mixed tumor was the most common(126 cases, 81.2%)and in the malignant tumors the mucoepidermoid tumor was the most common(12 cases, 50%). 4) The truncal approach for parotidectomy was used in 171 cases, and the peripheral approach in 8 cases. 5) The peripheral approach is superior to the truncal approach because it can provide with a better surgical field ; the branches of facial nerve can be identified more superficially, and thus the liability of facial nerve injury is much lessened especially in large tumors. The peripheral approach also coincides with the embryologic development of parotid gland.

Light emitting diode를 이용한 광중합 시 금합금과 교정용 금속 브라켓의 전단접착강도

정민호,정신혜,손원준 대한치과교정학회 2010 대한치과교정학회지 Vol.40 No.1

성인 교정환자의 수요가 증가하면서 보철물 표면에 교정장치를 부착해야 하는 빈도가 늘어나고 있다. 본 연구는 금속표면에 교정장치를 직접 접착하고자 할 때 사용하는 metal primer와 silicoating으로 각각 금합금의 표면을 처리한 후 light emitting diode (LED) 광중합기를 사용하여 광중합을 시행하여 접착력을 평가해 보고자 하였다. Type III gold alloy 표면에 aluminum oxide를 이용한 sandblasting 후 4-META 계열의 metal primer로 처리한 시편과 silica를 이용한 sandblasting 후 silane으로 처리한 시편에 광중합형 접착레진인 Transbond XT를 이용하여 금속 브라켓을 접착하고 접착 후 1시간, 6시간, 24시간 후 전단접착강도의 변화를 비교, 관찰하였다. 측정된 값을 이원분산분석(two-way analysis of variance)을 이용하여 비교하고 두 가지 표면처리 방법 간에 접착강도에 차이가 있는지도 살펴보았다. 연구결과, metal primer에 비하여 silicoating을 시행한 시편에서 높은 전단접착강도가 관찰되었으며, 시간이 경과할수록 접착강도가 증가하는 경향을 보였다. Adhesive remnant index (ARI)에서는 군 간 유의한 차이를 보이지 않았다. LED를 이용하여 광중합을 시행하는 경우 법랑질에 비하여 긴 시간의 광중합을 실시하고 metal primer보다는 silicoating 방법을 사용하는 것이 금합금표면에 교정장치를 부착할 때 더 높은 접착강도를 얻을 수 있을 것이다. Objective: The need to bond orthodontic brackets onto various alloys has increased because of the increasing demand for adult orthodontic treatment. This study tried to evaluate the shear bond strength between gold alloy and metal bracket using light emitting diode (LED) light curing after metal primer and silicoating surface conditioning. Methods: Half of the type III gold alloy plates were treated with sandblasting with aluminum oxide and metal primer containing 4-META, the other half were treated with silica and silane. Metal brackets were bonded with Transbond XT light curing adhesive on these plates and shear bond strength were evaluated 1 hour, 6 hours, and 24 hours later. The differences of shear bond strength between groups were evaluated with two-way ANOVA. Results: The results showed higher bond strength in the silicoating group and a tendency of bond strength increase over time. Conclusions: When using LED curing lights for metal bracket bonding to alloy surfaces, long curing time and silicoating can produce a reliable bonding strength.

단체급식소 12개소의 식단을 수거하여 각 메뉴별 및 1인분 식단별 NA 함량을 분석하였고 인공소화 기법을 활용하여 체내에서 생성 가능한 NA의 함량을 예측하였다. 육류와 어패류를 주재료로 요리된 메뉴들의 인공소화 전·후 NA 함량을 분석한 결과 멸치볶음에서 NDMA 함량이 흔적량 ~ 4.8 ㎍/kg으로 가장 높았고, 채소류를 주재료로 한 메뉴들에서는 불검출에서 흔적량의 NDMA가 정량되었으며, 인공소화 후에도 흔적량 이하로 정량되었다. 1인 분량의 식사를 수거하여 인공소화 전·후의 NA를 분석한 결과 NDMA는 인공소화 전 0.20 ~ 0.78 ㎍/kg의 범위였으나 인공소화 후에는 0.43 ~ 0.80 ㎍/kg으로 약간 증가하였다. 상기의 분석 결과를 기초로 하여 성인 1일 NA 섭취량을 계산한 결과 0.60 ~ 2.34 ㎍/day/person이며, 인공소화를 통한 체내에서의 생성량을 고려하면 최대 5.15㎍/day/person으로 추정된다. N-nitrosamine (NA) contents depending on simulated gastric digestion were analyzed with 12 kinds of diets collected from institutional food service those diets were estimated the total NA amounts including both intake from food directly and its endogenous formation in human body from simulated gastric digestion. NA was determined in dishes of meats, fished and vegetables before and after simulated gastric digestion. N-nitrosodimethylamine (NDMA) contents were from not detected(ND) to 4.8 ㎍/kg in dishes of meats and fishes. After digestion, its contents increased and the highest level was 3.0 ㎍/kg in panbroiled dried anchovy. In vegetable dishes, NDMA was detected as ND ~ trace before and after digestion. The contents of NDMA in diets collected from institutional food service were 0.20 ~ 0.78 ㎍/kg, 0.43 ~ 0.80 ㎍/kg before and after digestion, respectively. The average intake of Na per day to Korean, based on the above data, was 0.60 ~ 2.34 ㎍/day/person. The maximum daily intake of NA was reduced to 5.15 ㎍/day/person when considering NA amounts formed endogenously by simulated gastric digestion.

The purpose of the study is to find out the influence of female physical self-efficacy on dance flow in a Korean dance program. The subject of the research is randomly selected 400 women enrolled in a variety of traditional Korean dance programs in cultural centers in Busan. The analysis of questionnaire used in this study came to the following conclusions. Women in their forties show the highest self-efficacy and The longer a woman participate m a dance program, the higher her self-efficacy. The dance commitment increases especially when a women participate in a program over 3 years. The higher a woman's self-efficacy, the greater her dance commitment. The subcategory of physical self-efficacy shows a great impact on one's dance commitment. These conclusions demonstrate that women in their forties who have been involved in a dance program for over three years with a high physical self-efficacy have the greatest dance commitment.

현재의 클라이언트 서버 환경에서는 수많은 이질적인 데이터베이스 서버들이 LAN과 WAN상에 분산되어 있다. 따라서 이들 서버의 위치에 관계없이 일관되고 확장성 있는 액세스 메커니즘을 클라이언트에게 제공하는 것이 필요하다. 본 논문에서는 라우팅 브로커링에 기초하여 분산되고 이질적인 데이터베이스에 대한 일관되고 위치 투명성과 확장성 있는 액세스 매커니즘을 제시한다. 본 고에서 제안한 메커니즘은 클라이언트와 다수의 서버사이의 중간계층으로서 작동되도록 java와 CORBA 그리고 JDBC의 최신 기술을 적용시켜 설계되었다. In current client/server environments, it is not uncommon to have multiple, heterogeneous database servers scattered on LAN or WAN. Therefore, it is desirable to provide clients with uniform and scalable access mechanism to connect to those servers in a location-transparent way. In this paper, we propose a uniform, location-transparent, and scalable access mechanism based on routing brokering scheme to access distributed, heterogeneous databases on LAN. The proposed mechanism is designed to act as a middle tier between clients and multiple servers, and adopts Java, CORBA and JDBC as its state -of-the -art techniques.
