This study analyzed the effect of career development system and personnel management equity on career success for workers who experienced various career change environments. The results of empirical study were as follows: First, it was found that career adaptation partially mediated career development system and career success relationship. Second, it was found that the moderating effects of personnel management equity on career success and career adaptation respectively. Third, it was found that the moderating effect of personnel system fairness was mediated by career adaptability in the relationship between career development system and career success. The analysis results confirm the importance of career adaptability and personnel system fairness for individual career success and suggest that the effectiveness of the career development system can be increased when the characteristics of career development and the personnel system are combined.

We examined the characteristics of temperature variation in Seoul between 1961 to 2008 using the spectral heteroscedastic model. The mean function in the propsed model explains the season effect using periodic functions and the overall increase using the quadratic regression spline. The variance function also had periodic functions to explain the seasonality of variance. We found that there has been annual mean temperature increase by about $1.5^{\circ}C$ for the last 48 years. The increase of annual mean temperature was mainly caused by the increase in winter, which made the amplitude decreased.

Purpose: Necrotizing fasciitis is a life-threatening, destructive soft tissue infection with a very high rate of mortality that needs early diagnosis and aggressive treatment. Systemic Lupus Erythematosus (SLE) is a systemic, autoimmune disease and it's major cause of mortality is an infection. But necrotizing fasciitis in SLE is very rare and there have been only 22 cases reported in the literatures. We reported a patient of necrotizing fasciitis with SLE and reviewed 22 others from literature research. Methods: A 40-year-old female patient with a history of SLE for 6 years came to the emergency room. The patient complained of severe pain and swelling on her right leg. She was diagnosed as necrotizing fasciitis and underwent emergency fasciotomy. As wound cultures showed variable organisms, she was treated with broad-spectrum antibiotics and underwent several surgical debridements. Then, the wound was treated with the V.A.C (Vacuum Assisted Closure) device and split thickness skin grafting was performed two times. Results: Skin graft was well taken within 2 weeks after operations and the patient was discharged to outpatient follow up. There was no complication related with surgery and she could walk without cane after 3 months. Conclusion: We treated a necrotizing fasciitis in a patient with SLE and reviewed 22 others from literature research. The case presented here suggests that necrotizing fasciitis is a rare disease in SLE patients, but should be considered in the differential diagnosis of soft tissue infection in SLE patients. A high index of suspicion is needed for early diagnosis and proper management in these patients.

This qualitative research investigated how to improve preservice and in-service teacher education programs through in-depth interviews with 10 exemplary science teachers. Data from interviews were used to analyze how the teachers perceived current situations of teacher education and what they suggested as an improvement plan. In terms of preservice teacher education, exemplary teachers argued that teacher education programs should (1) ensure the teacher education program's identity and goals, (2) provide preservice teachers with practical knowledge by translating theory into practice, and (3) secure faculty members who majored in science education. In light of in-service education, the teachers contended that (1) teachers should acknowledge the continuing processes of their own professional development, (2) the content and method of in-service training should incorporate teachers' practical needs in the classroom, and (3) the teaching community should implement a clinical supervision to improve their classroom practices. The central role of teacher (re)education in a successful classroom reform is also discussed.

These studies were conducted to investigate the changes and relation in protein, rheology and bread-mating properties during hard and soft wheat maturation. Samples were collected from the fields at 25 to 50 days after heading at intervals of 5 days. Protein content, sedimentation value and Pelshenke value of the tested wheat kernel or flour differed significantly between hard and soft wheat, and was relatively constant at 35 to 40 days after heading in each cultivar. In Mixogram water absorption of the flour, soft wheat increased only slightly, while intermediate and hard wheat increased remarkedly with maturation of the kernel. Total Mixogram characteristics increased and reached its maximum level at 35 days after heading. Farinogram pattern and bread loaf volume of the flour was greatly differences at the early stages of development due to cultivar, and was relatively constant at 40 days after heading. Significant positive and negative correlations were obtained among the protein and rheological properties, and tread loaf volume as the kernel matured.

Changes of proteins of whole soybean and soy flour stored under different conditions of humidity (RH 65% and 85%) and packing material (HDPE and OPP/Al/PE film) for 90 days and their influence on formation of soybean curd were investigated. The water holding capacity, total nitrogen, soluble nitrogen, pH and Amylograph viscosity of whole soybean and soy flour were rapidly decreased during storage at high relative humidity. Furthermore, such quality changes were accompanied by considerable differences in final quality of soybean curds; lower volumes of soybean curds. Under the conditions of HDPE and OPP/Al/PE film packing, smaller changes were observed in protein qualify than those without packing.

This study investigated the current science teaching evaluation system implemented in schools and directions for improving teaching evaluation using literature review, survey, and teacher interview. The first part of this paper analyzed the types, roles, and major issues of the current science teaching evaluation. In-service teachers argued that the current teaching evaluation system was discredited because of the bureaucratic procedures of teacher performance review, showcase classrooms, teachers' views on classroom as their own personal space, low ratio of teaching component in the current teacher evaluation, untrained evaluators, and the absence of professional teaching standards. The second part of the paper investigated the need for a formative teaching assessment, an ideal type of teaching assessment, and the role of participants in the teaching evaluation processes. The way forward, therefore, is to start not at the level of the administrative superstructure but at the level of teachers who will assume responsibility for developing standards of practice as the basis for evaluating their own work and improving their own professional learning to provide quality assurance.

Quality changes of filter-sterilized Yakju were examined by filtration of Yakju through membranes followed by storing at $25^{\circ}C$ for 50 days. To evaluate quality changes of filter-sterilized Yakju, pH, titratable acidity, turbidity, and viable cell numbers of total bacteria, lactic acid bacteria, and yeast were measured. Titratable acidity, turbidity and viable cell numbers of non-sterilized Yakju increased, but pH profile decreased during the storage. In filter-sterilized Yakju, titratable acidity and turbidity did not change, while viable cells of total bacteria, lactic acid bacteria, and yeast were not detected during the storage. Addition of chitosan at the concentration of 0.1% (w/v) decreased the viable cell numbers significantly showing similar pH and titratable acidity profiles with non-sterilized Yakju.
