This study aims to provide fundamental data for developing a parent education program for family leisure and analyzing the needs of the parents raising adolescent children on parent education for family leisure. The subjects were 287 parents raising second and third year students at middle schools. They were intentionally sampled from the middle schools at Seoul, Gyeonggi, Daejeon, Donghae, Samcheok and Changwon. This study results can be summarized as follows: First, the degree of aid expectation for parent education for family leisure was high. The degree of aid expectation by demographic variable showed significant differences, according to the educational background of father, religion of parents and job of parents. Second, among family leisure activity types, education needs for education- and experience-oriented activities were highest. The average education needs for family leisure activities, including each family leisure activity type, were 2.95/4, which was relatively high. Third, as for the needs of parent education methods for family leisure of the parents raising adolescent children, the needs for program contents were highest in attending lectures. Weekday mornings and children's non-vacation season were the highest program practicing times. In teaching methods, participating activities showed the highest needs; in session, one or two second sessions were the highest.

The purpose of this study was to investigate the effects of sanitary education on the sanitary knowledge and performance levels of school foodservice employees in Gyeonggi-do, particularly in Siheung, Ansan, Gunpo and Anyang City. Four times we provided questionnaires consisting of the same content to each individual. The first and second questionnaires were answered before and after the first sanitary education, respectively, and the third and forth questionnaires were answered before and after the second sanitary education, respectively. The changes in sanitary knowledge and performance level before and after education were statistically significantly different(p<0.01). Most of the school foodservice operations performed sanitary education once a month, and recognized the need for sanitary education as well as experienced improvements through sanitary education. Moreover, the fact that sanitary knowledge following the second education was higher than after the first education suggests the possibility of improving sanitary practices of foodservice employees through continual education.

Objectives: The purpose of this study was to analyze related factors in relation to usage of illicit substances for Korean adolescents. Methods: This was a cross-sectional study, which used data from the Twelfth Korean Youth Risk Behavior Web-based Survey (KYRBWS). A total of 65,528 students in 2016 were included in this study. Chi-square test and logistic regression analysis were used for analyzing related factors using illicit substances. Results: Overall, 553 (0.8%) students responded as having ever used illicit substances during their lifetime and 133 (0.2%) students responded as current illicit substance users. It was found that electronic cigarette (EC) use, conventional cigarette smoking, second hand smoking, sad/despair mood, and economic status were significantly associated factors with usage of illicit substances. Comparing 'current EC users' with 'never EC users', the adjusted odds ratios (OR) was 7.76 (95% confidence interval (CI): 5.56-10.82) for life-time use of illicit substances, and 18.74 (95% CI: 8.01-43.87) for current use of illicit substances among adolescents. Additionally, comparing 'students who ever were exposed to second hand smoking during the past week', with 'students who never were exposed to second hand smoking', the adjusted OR was 2.60 (95% CI: 2.13-3.17) for life-time use of illicit substances, and 2.85 (95% CI: 1.68-4.83) for current use of illicit substances among adolescents. Conclusions: Based on the results, electronic cigarette use, second hand smoking, conventional cigarette smoking, sad/despair mood, and economic status were significantly associated with increased odds of substance experience and current substance use. Therefore, the results of this study can provide a useful evidence about adolescent behaviors in predicting substance use.

Purpose : To assess the clinical results of second toe-to-finger transfer in traumatic amputated index finger. Materials and Methods : For the clinical evaluation, we have analyzed 12 patients with ROM of finger joints, pinch power, static two point discrimination, life functional assessment, and patient's satisfaction. Results : In genral ROM was $54.4^{\circ}$ at MP joint, $17^{\circ}$ at PIP joint and $6.7^{\circ}$ at DIP joint. Pinch power was good in 3 cases, fair in 7 cases, and poor in 2 cases. Daily life activity and patient's acceptance were satisfactory. Conclusion : Although transfered toe function may be poorer than normal finger, the hand was restored to a useful, sensate and versatile functional unit.

Two types of the thioltransferase (also called glutaredoxin) have been previously detected in the cytosolic extract of Schizosaccharomyces pombe, a fission yeast. Previously, the one with a smaller molecular mass (14kDa) was purified and characterized. In the present study, the second thioltransferase was purified. The purification procedure included ammonium sulfate fractionation (40-80%), Sephadex G-200 gel filtration, DEAE-cellulose ion-exchange chromatography, Sephadex G-50 gel filtration, and glutathione-agarose affinity chromatography. The purified enzyme showed a single band on SDS-PAGE, and its molecular mass was determined to be 23 kDa. It utilizes various compounds as substrates, including 2-hydroxyethyl disulfide. Interestingly, we found that the purified thioltransferase also contains significant glutathione S-transferase activity.

Learning system on virtual environment gives the immersive feeling that lacks in existing E-Learning system, excites user's interest, and offers dangerous and expensive education contents. In this paper, we classified the learning categories into four classes: realtime lecture, anytime study, practice education, and the activity of study group. We built the on-line lecture system using Second Life that supports 3D virtual world and mixed reality. We provided virtual learning environment as running developed virtual world on-line lecture system.

Mormonilla phasma is redescribed, based on the specimens from the Northeastern Pacific. M. phasma in the study area has the following morphological characteristics; second endopodal segment of mandible partly fused to basis and a distinct three-segmented exopod of mandible in anterior view and one indistinct segment in posterior view which are different from the description given by Boxshall (1979). In addition the first and the second endopodal segments of leg 1 were also separated indistinctly. Other morphological characteristics are similar to those reported in previous studies. The morphological anomalies in endopodal segments of the leg 1, unknown up to now are also discussed. This study is the first report on the distribution of M. phasma in the Northeastern Pacific.

Kushia zosteraphila Harris V.A. & Iwasaki, 1996 is newly collected and described from macroalgae in the intertidal region of Gijang-gun, along the southeastern coastal region of Korea. Kushia zosteraphila can be distinguished from congeners by following morphological characteristics: the length of the first dorsal seta similar with the second dorsal seta of female P5, the length to width ratio of the female caudal ramus, and the presence of a conspicuous comb on the accessory lobe of the male antennule. Although there are some minor discrepancies, the main diagnostic characteristics of the specimen from the study area are well-matched with the original description. We herein provide detailed morphological descriptions and illustrations of this species. According to a survey of the location of the reported porcellidiid species in Korea, this specimen is the second record in Korean waters of the genus Kushia. A key to species of the family Porcellidiidae in Korea is provided. A partial sequence of the mitochondrial COI gene was obtained and provided as a DNA barcode for this species.
