The purpose of this study is to verify the effect of Interdisciplinary course for improving the competency of collegiate Interpersonal & Cooperative Skills, Resources-Information-Technology Processing & Application and Communication. The course proved to be effective based on the result for examination of difference between the experimental group of 43 students who took the interdisciplinary course and the control group of 44 students who did not take that course of the second semester of H university in 2015. The study applied the method of Paired-sample T-Test to investigate the difference of Interpersonal & Cooperative Skills, Resources-Information-Technology Processing & Application and Communication and their sub-skills between the two participant groups. As a result, Interdisciplinary course had an effect on improvement of Interpersonal & Cooperative Skills and it's sub skills; however, it had no effect on improvement of Resources-Information-Technology Processing & Application and Communication competency and their sub-skills. The results provide theoretical and practical implications for the interdisciplinary course and core competence of college students. They suggest that interdisciplinary course design should be more careful to improve students' competency on Resources-Information-Technology Processing & Application and Communication competency than before.

As the competition between companies are deepened, the number of companies adopting six sigma principles, which is one of the innovative management strategies, are increasing. According to this trend, the changes in both strategies and methodologies of six sigma are continuous. However, the evaluations and the management principles included in the process after the six sigma applications are insufficient, and the cooperation between the parties in the company is also not enough because the application process of six sigma is too complex and not efficient. In order to solve this problem, a research for developing the methodology which can learn about and do six sigma applications is so necessary, specifically for expanding the six sigma applications and introducing the participation of all company members. The purpose of this study, therefore, was to develop and present more efficient Six Sigma applied process by reducing the existing unnecessary steps in improvement one, by applying the examination method of wasteful elements on the potential factors, through analyzing the Six Sigma DMAIC applied case in the construction industry. The result of those application showed that the detection of potential factors using wasting elements was possible in measurement step and that it was possible for the improved process with reduced steps compared to existing process while to remain the outcomes. It is considered that the performance rate of Six Sigma project will be improved significantly because the reduction in the improvement step does not affect the improvement effect within the whole Six Sigma project.

The stylobate for expanding the external stage area was the most frequently installed installment out of the installments installed for royal court ceremonies. The stylobate was installed for various ceremonies such as funeral rites, ancestral rites, customary formalities, state examination, feasts for celebrating a honored guest of the court, queen's silkworm cultivating ceremony, heir appointment, the presentation of honorary titles for the king or queen in honor of their merits, and entertainment of foreign dignitaries. The exact period stylobates came to be used for the play stage. The stylobate consists of the 紅座板, 屯太木, 竹欄間, 足木, and the 層橋. Depending on the 足木, the substructure of the stylobate, the stylobate could be divided into the 長足木, 中足木, 短足木, 平足木 type. The detail structure of the stylobate changed in form from the jokmok and duntaemok that appeared until the time of King Seonjo, into the 長屯太木, 短屯太木, and the 短短屯太木 during the time of King Heonjong. With the introduction of the 中足木, materials began to become more segmented and the structure stronger. According to existing records, while the height of the stylobate was not significantly high prior to King Seonjo's reign, the 十四層雲橋 and the 十三層層橋 introduced during the time of Emperor Gojong was designed to reflect his rank in external ceremonies while the eight story step bridge was exhibited in internal ceremonies to reflect the rank of Queen Mother Sinjeong. From here, we can deduce that the fourteen and thirteen story cloud bridges representing the king was of a higher grade than the eight story step bridge which represented the queen mother. Finishing by adding boards to the lower part of the stylobates began to appear in the time of King Seonjo. During King Heonjong's reign, the lower finish became gentrified with a thin board called 修粧板, and yeomupan 廉隅板 for decorating the edges of the stylobates were installed. Such style of finishing the lower part of the stylobate with boards mostly appeared in elaborate feasts 進饌 and celebrations 進宴 within the royal court 內宴. The stylobates appeared to have served not only practical purposes such as expanding the stage area, but also as installments which realize the authority and prestige of the royal crown. They were installed according to the purpose of the ceremony and the rank of the participant. In short, stylobates became established during King Seonjo's reign, became segmented and gentrified during King Heonjong's reign, and began to take height variations during Emperor Gojong's reign to reflect the rank and authority of the king and queen mother. As such, it can be considered another characteristic of Joseon Dynasty architecture.

This study analyzed the academic achievements on above-level testing of mathematics, physics, chemistry, and English in newly entering students of science specialized high schools. It can be expected that newly students of science high specialized schools have reached ceiling level in the middle school mathematics and science academic scores. Above-level testing(or off-level testing) is a test tool used to evaluate student's ability which are above-grade level. In this study, above-level testing tools were used to develop the same type examination paper of the 2013 Korean College Scholastic Ability Test(CSAT) in mathematics, physics, chemistry, and English. The conclusions of this study were as follow: First, the academic achievement level of science specialized high school freshmen were higher the average level of general high school senior because that over 50% of them are within the 5 grade of CSAT in mathematics, physics, and chemistry. In English, 19.3% science specialized high school freshmen have reached within the 5 grade of CSAT. Second, as a result of examining characteristics of academic achievement with respect to units of subjects, in mathematics, it was showed that the academic achievement of 'continuity and limit of a function' unit was higher, 'statistics' unit was lower. In physics, the academic achievement of 'Electricity and Magnetism' unit was higher, 'Waves and particles' unit was lower. In chemistry, the academic achievement of 'compounds in life' unit was higher, 'Air' unit was lower. In English, the academic achievement of 'practical sentence' of reading area was higher, 'Sentence' of writing area was lower. In conclusion, above-level testing provided a good strategy for identifying and determining appropriate programming interventions for gifted students who are two or more grade levels above their age-mates in achievements, aptitude, or ability.

Objective: The use of nanoparticle products is expected to present a potential harmful effect on consumers. Also, the lack of information regarding inhaled nanoparticles may pose a serious problem. In this study, we addressed this issue by studying pulmonary toxicity after nasal instillation of Al-NPs in SD rats. Methods: The animals were exposed to Al-NPs at 1 mg/kg body weight (low dose), 20 mg/kg body weight (medium dose) and 40 mg/kg body weight (high dose). To determine pulmonary toxicity, bronchoalveolar lavage (ts.AnBAL) fluid analysis and histopathological examination were conducted in rats. In addition, cell viability was investigated at 24 hours after the treatment with Al-NPs. Results: BAL fluid analysis showed that total cells (TC) count and total protein (TP) concentrations increased significantly in all treatment groups, approximately two to three times. Also, lactate dehydrogenase (LDH) and cytokines such as TNF-alpha and IL-6 dose-dependently increased following nasal instillation of Al-NPs. However, polymorphonuclear leukocytes (PMNs) levels showed no significant changes in a dose dependant manner in BAL fluid. In the cytotoxicity analysis, the treatment of Al-NPs significantly and dose-dependently induced cell viability loss (20 to 30%) and damage of cell membrane (5 to 10%) in rat normal lung epithelial cells (L2). Conclusions: Our results suggest that inhaled Al-NPs in the lungs may be removed quickly by alveolar macrophages with minimal inflammatory reaction, but Al-NPs have the potential to affect lung permeability. Therefore, extensive toxicity evaluations of Al-NPs are required prior to their practical application as consumer products.

Epidemiologic research has suggested that frequent eating out may be associated with poor dietary habits, including high-calorie and inadequate nutrient intakes. Limited studies, however, have evaluated dietary behaviors with patterns of eating out in South Korea. The aims of this study were to examine the associations between nutrient intakes, adherence to dietary guidelines, and frequencies of eating out among Korean adults. Data were analyzed from adult (30 to 64 years old) participants of the 2007~2009 Korean National Health and Nutrition Examination Survey (n=10,223). Nutrient intake levels were assessed by the 24-hour recall method. The dietary score (DS-ADGK) was calculated based on the adherence to dietary guidelines for Koreans. Subjects who frequently consumed meals outside the home tended to be younger, male, urban-dwelling, highly educated, and receiving a higher income. The frequency of eating out was positively associated with the higher intake of most nutrients, except carbohydrates and crude fiber. Regular breakfast habits seem to be associated with the frequency of meals outside the home for women; younger women who frequently eat out tended to have irregular breakfast eating habits, but this association is attenuated with increasing age. The mean DS-ADGK differed by sex, age, and the frequency of eating out; older participants scored higher than the younger ones, women had higher scores than men, and those who frequently eat out had lower scores than their counterparts. In addition, the adherence score for each component of the dietary guidelines was also significantly different by age and sex. The consideration of demographic characteristics related to frequent eating out and other barriers to healthful eating, as well as essential and practical interventions, are needed to promote positive dietary behavioral changes in Korea.

The water quality of the Gulpo Stream flowing through Incheon, Bucheon, Seoul, and Kimpo is getting worse due to a slow flow rate and bank constructions by stream channelization as well as an inflow of pollutants from living-sewages and factory-sewages. Besides, a dry stream phenomenon caused by a lack of maintenance water upstream makes a self-purification system worse, and the water quality of the Gulpo Stream is currently at its lowest level. The accumulated sludge of the streambed is mostly formed by the deposition of particle pollutants due to the slow flow rate and an artificially straightened stream channel. This accumulated sludge adsorbs a great quantity of organic materials and heavy metals. Because of the internal contamination possibility by a re-gushing, even after the pollution source is removed, it can cause future water pollution. Without a total examination as previously recommended, it is considered difficult to accomplish practical efficiency. In conclusion, the management of periodic sediment management such as dredging would be necessary in the Gulpo Stream because sediment could be an internal pollution source of stream water under anaerobic conditions.

The Campus Core is centered at the physical, functional and symbolic environment of a university, which is known as the top academic institution, hence it metaphorically represents not only the educational philosophy when institution first opened, but also the transformed values of the time. Today, universities are asked to actively communicate with the local community in terms of function and be remodeled as pedestrian-friendly campuses in terms of physical environment. For this reason, the study comprehends the concept of the campus core in accordance with a pedestrian-friendly environment and suggests a practical plan for campus cores of district national universities based on previous research examination. Since the purpose of the study is to suggest a change in the circulation system centered on vehicle use to transform into a pedestrian-friendly environment through a planned approach while introducing public mixed-use at the same time, the study supports the fact that it is possible to reorganize the strategy of a pedestrian-friendly circulation system and partially revise the land utilization to yield the expected outcomes. Thus, this study will provide valid suggestions for similar maintenance plans while looking back to the meaning and value of today's campus core.

This study examines the issue of causality between ocean industries and urban economic growth in the sea port city. To maximize economic advantage of Busan as a sea port city, we first need to analyze the effects of ocean industries on urban economic growth. This study focuses on the examination of the role of ocean industries and its related variations in economic growth at the urban level. Using data from Busan. Metropolitan City in Korea during 1985-2011, we find that the causality link between ocean industries and urban economic growth rates runs in both directions. Especially, industries of shipping/port, marine tourism, and shipbuilding were the most important variables in Busan economy. With this information, the empirical results show that ocean industries and its related variations have significant effects on urban economic growth. Based on these significant research findings, theoretical and practical implications were discussed.
