This study was done to determine the regional adaptability of Dioscorea opposita in Korea. Suwon, Chunchon, Kangneung, Yonchon and Taean had soil pH of 6.62, 5.65, 5.9, 5.9 and 5.82, respectively, being at more unfavorable conditions than a standard soil condition for yam with pH 6.2. The amounts of organic matter in Suwon, Chunchon, Taean, and Yonchon were 1.96%, 4.51%, 3.76%, 1.89% and 1.12%, respectively, being at more favorable conditions than a standard organic matter in soil for yam with 2.0~3.0%. As the results from cultivating of large plantings in different regions, Suwon showed the largest the tuber dry weight of 135g. In comparison of general component between round yam and short yam in the area of Kangneung, protein of round yam(3.30%) was higher than that of short yam(1.40%). Dryness in round yam(36.5%) was lower than that of short yam(28.9%), indicating a higher dry weight ratio of round yam. In tuber extracts analysis, saponins content was respectively 23.7mg/g in round yam and 10.4mg/g in short yam.

The purpose of this study is to develop a tea culture therapy program development for the improvement of self-efficacy of juvenile probationers, which is a key factor of social adaptability of juvenile probationers. After developing a tea culture therapy program, this study examines the effect of the program empirically, by applying to juvenile probationers. For this purpose, this study employs an integrative approach of qualitative and quantitative methods. It is shown from the qualitative analysis that juvenile probationers' positive attitude and active participation are considerably progressed. The results from quantitative analysis indicate that the sub-dimensions of self-efficacy such as general self-efficacy and social self-efficacy are significantly improved.

Purpose: The purpose of this study was to identify the types of family function and mental health in low-income middle aged women using the circumplex model. Method: A descriptive research design was used. A sample of 116 low income middle aged women participated in the study. The Family Adaptability and Cohesion Evaluation Scale III was used to measure the types of family function. Mental health was measured by the SCL. Results: The types of family function identified were balance family (59.4%), extreme family (25.9%), and mid-range family (14.7%). Significant differences were found in mental health by the family cohesion (F=3.44, p=.019) and family adaptability (F=3.31, p=.023). The mental health status of extreme family was better than mid-range family and balanced family, but such result was not statistically significant (F=0.25, p=.783). Conclusion: The Circumplex model's main hypothesis was not empirically supported that extreme family has more problematic than mid-range family and balance family. These findings emphasize the need for the development of a family system model for Korean family.

Surgeons are increasingly using the right mini-thoracotomy approach to perform aortic valve surgery. This approach has shown better results in terms of blood loss and length of hospital stay than the sternotomy approach. For selected patients requiring aortic root and ascending aorta surgery, a right mini-thoracotomy approach may prove beneficial. In our technique, we placed a 5-cm horizontal skin incision in the right second intercostal space. Femoro-femoral cardiopulmonary bypass was established. A valved aortic conduit was used for aortic root replacement. The patient's postoperative course was uneventful, with a short hospital stay. This technique offers a minimally invasive approach to aortic root and ascending aorta surgery with easy adaptability and reduced costs.

This study was conducted to compare global mindset competency between engineering and non-engineering college students. Participants were 100 engineering and 202 non-engineering college students. Results indicated that engineering college students showed significantly lower mean scores on foreign understanding and self-directed adaptability than non-engineering college students, whereas there were no significant differences on self-ratings of foreign language ability. Hierarchical regression analyses revealed that the incremental validity of global mindset competency factors on global competency was significant. Finally, limitations of the present study and suggestions for further studies were discussed.

In this paper, the maritime educational and training systems in different countries were compared and analyzed. The sample countries have been divided into two large groups, one of which comprising the countries adopting European maritime educational system and the other of which consisting of countries adopting American maritime educational system. From the comparison of the two educational systems, the merits and demerits of each system has been analysed. The results of the analyses show that the maritime educational institutes of the countries such as U.S.A., Japan, Korea, Taiwan, which have American maritime educational system, have more adaptability to the rapidly changing, shipping environment. In addition, it has been concluded that the college of the Maritime Science of the Korea Maritime University is required to set up a new educational model which is similar to the of the SUNY Maritime College in the U.S.A to meet the recent changes in Korean shipping industry.

Varietal difference in nitrogen metabolism was investigated under water culture system with high (50 or 80ppm) and low (10 or 40 ppm) levels of nitrogen and with two-week minus nitrogen treatment at maximum tillering and heading stage using a leading local variety, Jinheung and high-yielding IR667 line (newly bred tropical variety). 1. In high nitrogen level Jinheung showed higher yield than IR667. vise versa in low nitrogen level. 2. Poor yield of IR667 at high nitrogen may be due to ammonium toxicity that was eliminated by minus nitrogen from culture solution. 3. IR667 was more sensitive to the change of nitrogen environment. 4. With high nitrogen medium Jinheung showed nigher nitrogen uptake and higher capacity of protein synthesis than IR667, and vise versa at low nitrogen medium. 5. From the above facts it could be concluded that Jinheung has higher metabolic adaptability for heavy nitrogen while IR667 has higher structural adaptability for heavy mitrogen and that better productive adaptability will be resulted in the combination of both characteristics.

Established microleakage tests have their own disadvantages. In this study, 3D reconstruction method was tried to overcome these disadvantages. Four types of microleakage tests were used and relationships among them were estimated: penetrated dye volume: marginal adaptability: degree of dye penetration and relative penetrated length to cavity wall. Twenty-four Class V cavities were bulk filled with composite (Esthet X) following surface treatments: N group (no treatment): E group (etching only): T group (etching + Prime & Bond NT). 50% silver nitrate was used as a dye solution after thermocycling ($5^{\circ}C{\;}&{\;}55^{\circ}C$, 1.000 times). Teeth were serially ground with a thickness of 0.2 mm. Volume of dye penetration was estimated from a three-dimensionally reconstructed image with a software (3D-DOCTOR). Percentage of margin without gap was estimated from SEM and degree of dye penetration and the relative length of dye penetration to overall cavity wall were also estimated. ANOVA and Scheffe test for dye volume, Kruskal-Wallis and Mann-Whitney test for marginal quality, Spearman's rho test for checking of relationships among methods were used. The results were as follows: 1. Dye penetration could be seen from several directions, furthermore, its volumetric estimation was possible. 2. Reverse relationship was found between dye volume and marginal quality (r = -0.881/ p = 0.004). 3. Very low relationship was seen between dye volume and two-dimensional tests (degree of dye penetration and relative length). However, 2D evaluation methods showed high relationship (p = 0.002-0.054) each other. 4. Three times vertical section could be recommended as a 2D test.
