Sustainable rates of sebum excretion(SRSE) was measured in seven women who had normal regular periods, none were taking oral contraceptives with no significant signs of acne or hirsutism, with assays for testosterone, dihydrotestosterone, dehydroepiandrosterone sulfate, and progesterone during menstrual cycle. The SRSE in omen during the follicular phase wa lower in the luteal phase (p <0.01)than in the men (p <0.01). However during the luteal phase the SRSE in the women was increased similar to the SESE in the men. We investigated the above horrnoies in relationship to the SRSE during the women's menstrua] cycle. During the follicular phase the hormone which was the most determining factor affected the SRSl was total testerone, while dihydrotestosterone was the most determining factor of the horrnone affecting the SRSE during the ovulation and luteal phase.

PURPOSE: To characterize MR findings of meniscal cysts of the knee. MATERIALS AND METHODS: We retrospectively reviewed knee MR images of surgically confirmed eighteen meniscal cysts. The location and shape of meniscal cysts were evaluated. RESULTS: Six of 18 cases were medial meniscal cysts and 12 of 18 cases were lateral meniscal cysts. Horizontal tears were present in all cases(100%). Four of 18 cases had rounded cysts and 14 of 18 cases had elongated cysts. In 3 of 6 medial meniscal cysts, cysts had dissected into the soft tissues distant from the meniscus, and connecting stalks were visualized. Three of 6 medial meniscal cysts were located adjacent to a meniscal tear. All of the lateral meniscal cysts occurred immediately adjacent to the meniscal tear. CONCLUSION: Meniscal cysts are associated with horizontal meniscal tear. The shapes of meniscal cysts tend to be elongated rather than rounded. Medial meniscal cysts occurred distant from or adjacent to the meniscal tear according to location of the tear. Lateral meniscal cysts occurred adjacent to the meniscal tear.

PURPOSE: To determine the usefulness of the fat-suppressed (FS) conventional spin-echo (CSE) sequence for the diagnosis of meniscal tears. MATERIALS AND METHODS: We retrospectively reviewed 323 MR images of the knee, the standard of reference being the findings of arthroscopy. In all knees, fast SE proton density-weighted and T2-weighted sagittal and coronal images and double-echo in steady state (DESS) sagittal images were obtained, and during 202 MR Procedures, FS-CSE T1-weighted sagittal images were also obtained. The results of MR imaging were then correlated with those of arthroscopy, the accuracy with which meniscal tears were diagnosed being compared between two groups: group I (202 knees for which FS-CSE T1-weighted sagittal images were obtained), and group II (121 knees for which these images were not obtained). For statistical analysis the chi-square test was used. RESULTS: In group 1, sensitivity, specificity and accuracy were 94.7%, 92.4% and 93.5%, respectively, for the medial meniscus, and 83.3%, 95.7% and 90.5% for the lateral meniscus. In group II, the corresponding findings were 92.5%, 94% and 93.3%; and 87.3%, 98.2% and 92.5%. The differences between the groups were not statistically significant (p>0.05) CONCLUSION: For meniscal tears of the knee, the addition of FS-CSE T1-weighted MR imaging to the fast SE proton density-weighted, T2-weighted and DESS sequences does not enhance diagnostic accuracy.

PURPOSE: This study was to understand and explain the adjustment of cancer patients receiving chemotherapy. Variables in this model were social support, uncertainty, resilience and coping. METHODS: The data were collected for approximately five months from May through to September 2006 with cancer patients receiving chemotherapy or cancer patients finished chemotherapy using self-administered questionnaires. Descriptive statistics program, Amos 5.0, was employed to verify the goodness of the hypothetic model and the hypotheses formulated in the study. RESULTS: The fitness of the finalized model turned out to be improved (chi2=332.644, df=70, GFI=.809, AGFI=.714, RMSEA=.138, AIC=402.644). Those variables made a 60.8% prediction of the patients adjustment. CONCLUSION: The hypothetic model presented in the study could serve to explain the adjustment of cancer patients receiving chemotherapy. Moreover, the use of the conceptual framework of the theory of planned nursing intervention would be very worthwhile as a strategy to boost the adjustment of cancer patients when receiving chemotherapy.

The purpose of the study was to investigate relationships among food safety training, knowledge, and practices of school food service employees. A questionnaire that identified employees' food safety training experience, knowledge, and practices was developed based on a review of literature. A total of 341 Korean school food service employees participated in the survey; the final usable responses were 293 (a response rate: 86%). Statistical analyses were conducted using SPSS for Windows (version 10). Most of the respondents (> 86%) took training sessions on 'proper hand washing' and 'proper food storage temperatures', whereas less than 60% had training on 'monitoring procedures and corrective actions at critical control points'. The mean score of their food safety knowledge was 8.02 out of 11. The majority of the employees knew correctly 'potentially hazardous foods (93.2%)' and 'diseases and symptoms with which they are excluded from working (87.0%)'; less than 50% chose a correct answer for 'sanitizing food contact surfaces.' A chi-square analysis revealed that the employees' actual knowledge did not differ significantly by whether they had food safety training (at the level of alpha = 0.01), except one topic "diseases and symptoms with which they are excluded from working." Their self-reported practice scores were rated as 2.98 - 3.39 based on a 5-point Likert-type scale (1-not at all, 5-always). Employees' food safety training should be conducted continuously and repetitively to improve the effectiveness of the training.
