  • 본 연구는 가맹본부의 과도한 통제로 인하여 가맹점사업자가 독립적 사업자가 아닌 피용자로 전환될 수 있음을 시사한 Williams v. Jani-king of Philadelphia Inc. 사건을 고찰하였다. 이 사건에서 법원은 가맹점사업자의 지위를 판단하기 위해 계약상 가맹본부가 행하는 통제의 성격이 유일하고 명백한 증거라고 판단하였으나 계약상 내용뿐만 아니라 실질적으로 가맹본부가 가맹점 사업자에게 행사는 통제의 정도도 함께 고려되어야 할 필요성이 있다. 또한 계약상 통제의 성격을 판단함에 있어 그 기준이 명료하지 않기 때문에 가맹점사업자의 지위 판단이 상황에 따라 달라질 수 있으므로 기존의 가맹사업상 내제된 통제와 그 이상의 일상적인 관리상 통제로 구분하여 가맹점사업자의 지위를 판단하는 것이 적절할 것이다.

  • The purpose of this study was to investigate the lift-style and eating behavior of stomach cancer patients in the Daegu and Kyungpook area, and to collect basic data for nutrition education designed to prevent stomach cancer in this community. The subjects of the study were 102 patients who were recently diagnosed as having stomach cancer at the Kyungpook National University Hospital. The control subjects were 105 persons who did not have any gastrointestinal disease, and included patients from the Department of Orthopedic Surgery and healthy volunteers. The survey, which covered the personal characteristics and eating behavior of the subjects, was conducted by individual interviews using questionnaires. It was found that the stomach cancer patients (case group) had experienced a significantly higher level of stress in their daily lives than the control group. A significantly higher proportion of the case group subjects recognized their personality as pessimistic, and had family histories of cancer, compared with the control group subjects. The cancer patients had higher preferences for salty and hot tasting foods, and tended to ingest meals faster without enough chewing, compared with the control subjects. The level of nutritional knowledge of the case group was lower than the control group, and there was a positive correlation between subjects' nutritional knowledge scores and nutritional attitude scores. Subjects' estimates of their food intake frequencies during the decade before the cancer was diagnosed revealed that the case group consumed significantly higher amounts of pickled fish, soybean paste soup and stew, cooked vegetables, beef and pork, charcoal broiled meat and alcohol, while consuming significantly lower amounts of green tea than the control group. In summary, the results of the study suggest that the stress of daily life, a family history of cancer, and a pessimistic personality might be the risk factors for the development of stomach cancer. Dietary factors which were suspected as risk factors for stomach cancer in the present study included strong preferences to salty and hot lasting foods, poor eating habits, and frequent consumption of pickled fish, soybean paste soup, cooked vegetables, beef and pork, charcoal broiled meat and alcohol. A high consumption of green tea seemed to be a protective factor against stomach cancer. The results of the study appear to provide useful data for nutritional education focussed on the prevention on stomach rancor in local residents.

  • Purpose: To examine the effects of a case management program on self-efficacy, depression and anxiety in pregnant women with gestational diabetes mellitus. Methods: Thirty-seven patients who enrolled in a diabetes outpatient clinic were randomly assigned to either an experimental group (n=19) or a control group (n=18). The experimental group received a 2-week intervention composed of a series of one face-to-face interactive interview and five telephone interviews based on the National standards for diabetes self-management education and Bandura's self-efficacy resources of performance accomplishment, vicarious experience, verbal persuasion, and emotional arousal. The effects of the intervention were assessed by completion of a 9-item self-efficacy questionnaire, a 20-item depression questionnaire and a 20-item anxiety questionnaire prior to, and after the intervention. The statistical significances were examined using t-test. Results: The change in self-efficacy was significantly greater in the experimental group than in the control group. Depression and anxiety changes in the experimental group were significantly greater compared to those in the control group. Conclusion: The results of study suggest that a case management program improves self-efficacy, and decreases depression and anxiety in pregnant women with gestational diabetes mellitus.

  • This study was peformed to investigate the effects on skeletal muscle recovery with aqua-exercise; swimming to take the muscle endurance for 20 days on two group of white rats which were the low extremity atrophy group(control groups) by fixed for two weeks and aqua-exercise group(experimental groups) after it. The effects was observed with light and electron microcope to measure the morphological changes of muscle fibers. The results obtained were as follow. 1. Light microscope: In the case of control groups, quadriceps fibers had been irregular alignment, decreased muscle width and the irregular alignment nuclear appeared, as it is degenerative muscle fibers. In the case of experimental groups, the fibers had been regular alignment cells and fibers. The nucleus of muscle had been normal characterized by oval shape and fiber sarcomere clearly classified. 2. Electron microscope: In the case of control groups, there were the quadriceps which was Z-line streaming phenomenon induced at the sarcomere and cells nuclear separated from basal membrane. It was not only observed the sarcomere alignment irregularly and mitochondria damaged, but also vacuoles found. In the case of experimental groups, A band, I band, H band had been clearly appeared, classified at the myofibrils of quadriceps, and electronic dense M-line found in sarcomere. There were observed satellite cells and basal laminas that usually to be appeared at the time of mitochondrial development, skeletal muscle fiber regeneration or development. This results suggest that the aqua-exercise assisted to inhibit the degenerative morphological changes of skeletal muscle cells and help to recover from abnormal states. Especially, it is considered to effect on a normal structural formation.

  • Objectives: The purpose of this investigation was to examine the association between endometrial cancer and possible etiological agents. Methods: A case-control study was conducted in Iran between March 2012 and May 2016. The demographic and reproductive factors of 205 women with endometrial cancer were compared, and 590 healthy cases were participated in the control group. For each endometrial cancer case, there were three controls, who were matched in terms of age and residence. The data were considered significant at $p{\leq}0.05$. Results: After adjusting the variables, the nulliparity (OR 6.23, 95% CI 2.86-13.59), the nulligravidity (OR 5.94, 95% CI 2.51-14.06), the positive family history of reproductive cancer (OR 4.97, 95% CI 2.33-10.59), the infertility history (OR 2.38, 95%CI 1.32-4.31), the obesity ($BMI{\geq}25$) (OR 1.71, 95% CI 1.16-2.52), the early menarche age (<12 years) (OR 2.10, 95% CI 1.17-3.75), and the hormonal contraception use (OR 1.69, 95% CI 1.15-2.49) were found to be associated with an increased risk of endometrial cancer. Nevertheless, the education level, the job of women, the marital age, the leisure activities, and the breast feeding were not found to be associated with the endometrial cancer after adjusting the variables. Conclusion: Scheduling of the screening program is vitally indispensable to identify endometrial cancer in women with nulliparity, nulligravidity and the positive family history of cancer. In addition, women with early menarche, those with the history of infertility, the obese ones, and those who use contraception pills need to be particularly aware of the potential risks.
