        Meoricho of Dancheong is a pattern that placed at the end of each elements. We call Dancheong which has Meoricho Moro-dancheong. Meorico is the pattern comes from the metal ornaments of ancient architecture. The most primitive forms of Meoricho is Saw-toothed Design. Since the influence of Buddhism in the Northern Wei dynasties Saw-toothed Design have changed Tied lotus Design. Tied lotus Design of the Unified Silla it becames Gak-yeop Design and Yeo-ui-doo Design Meoricho in Goryeo Dynasty. Since Goryeo Dynasty there’s been great and small variations in the internal composition of Meoricho, but the outline has maintained as it was. Therefore the completed form of the outline of Meoricho could be regarded as the one that was formed in Goryeo Dynasty.

        점토를 이용하여 세 종류의 새로운 형태의 변형된 유기물점토를 제조하였다. Cetylpyridinium chloride (CPC)를 점토에 층간 삽입시켜 OC-CPC를 합성하였고, Aluminium 축을 갖는 Al-PILC 만든 후, cetylpyridinium chloride를 Al-PILC에 삽입시켜 IOC-CPC 화합물을 합성하였다. IR과 TGA를 이용하여 이들 구조를 분석한 결과 층간 삽입반응이 성공적으로 이루어졌음을 확인할 수 있었다. X-ray 회절을 이용하여 층간 거리를 조사하였는데 OC-CPC가 제일 큰 값을 보여 주었다. 층간 구조를 갖는 화합물들은 삽입반응을 이용하여 구조를 변형시킬 수 있으며 이를 통해 층간거리, 표면적, 공간 크기, 화학적 친화성 같은 여러 물리적 성질들을 바꿀 수 있으므로, 본 논문에서는 자연점토를 이용하여 층간 반응을 통해 휘발성 유기화합물의 흡착에 쓰일 수 있는 유용한 유기점토 화합물을 합성하고 이들의 구조를 확인코자 하였다. 벤젠과 톨루엔의 흡착은 IOC-CPC나 Al-PILC에서 보다 OC-CPC에서 더 잘 이루어졌으며, 자연점토에서는 거의 흡착이 일어나지 않았다. OC-CPC 화합물에서는 친 소수성 성질이 크고 층간 거리도 증가했기 때문에 흡착이 잘 일어났다고 볼 수 있으며, 반면에 친수성이 큰 Al-PILC 에서는 벤젠과 톨루엔 같은 휘발성 유기물에 대한 흡착이 상대적으로 적게 일어났다.

        The objective of this study was to determine the changes in content of polyphenolics, flavonoids, amino acids, especially γ-aminobutyric acid (GABA), and the antioxidant activities in the methanol extracts of four different pigmented rice seeds (white, black, red, and green color) at different germination stages, dry seeds (DS), imbibed seeds (IS), and germinated seeds for 1 (GS1), 2 (GS2) and 3 days (GS3). Total phenolics content at 1000 mg/kg extract was highest in black rice, ranging from 208.3 to 257.3 mg/kg, and followed by red rice 144.7 to 185.7 mg/kg, brown rice 151.3 to 194.2 mg/kg and green rice 125.7 to 160.7 mg/kg (lowest). Total flavonoid level had same tendency to total phenolics among colored rices with significant differences, showing highest amounts (45.2 to 56.8 mg/kg) in black rice and lowest (18.8 to 23.0 mg/kg) in green rice. Total phenolics and total flavonoids levels in black and brown seeds were highest when soaked, and in red rice when nonsoaked, and in green rice when germinated for 1 day. These results showed that content of physiologically- active substances were differ depending on seed coat color, soaking or germinating degree. Content in total amino acids during germination was ranged from 136.5 to 232.0 mg/kg in green rice (highest), and 98.9 to 176.0 mg/kg in red rice (lowest). Total content of amino acids and GABA level in all seed colors were high in order of GS3 > GS1 > IS > DS. The antioxidant activity of the methanol extracts from all the seed colors concentration-dependently increased. DPPH free radical scavenging activity at 2,000 mg/kg was highest in black rice by 83.0 to 87.7%, and lowest in green rice by 44.3 to 65.7%.

        PURPOSES : This study is aimed at development of a stochastic pavement deterioration forecasting model using National Highway Pavement Condition Index (NHPCI) to support infrastructure asset management. Using this model, the deterioration process regarding life expectancy, deterioration speed change, and reliability were estimated. METHODS: Eight years of Long-Term Pavement Performance (LTPP) data fused with traffic loads (Equivalent Single Axle Loads; ESAL) and structural capacity (Structural Number of Pavement; SNP) were used for the deterioration modeling. As an ideal stochastic model for asset management, Bayesian Markov multi-state exponential hazard model was introduced. RESULTS: The interval of NHPCI was empirically distributed from 8 to 2, and the estimation functions of individual condition indices (crack, rutting, and IRI) in conjunction with the NHPCI index were suggested. The derived deterioration curve shows that life expectancies for the preventive maintenance level was 8.34 years. The general life expectancy was 12.77 years and located in the statistical interval of 11.10-15.58 years at a 95.5% reliability level. CONCLUSIONS : This study originates and contributes to suggesting a simple way to develop a pavement deterioration model using the total condition index that considers road user satisfaction. A definition for level of service system and the corresponding life expectancies are useful for building long-term maintenance plan, especially in Life Cycle Cost Analysis (LCCA) work.

        Kim, Deok-ho. 2017. “A Study on the Analysis of the Changing Process of Dialect Distribution with a focus on Methodology of Geolinguistics”. The Sociolinguistic Journal of Korea 25(1). 1~26. The purpose of this study is to analyze the process of changing the distribution of dialects through a geolinguistic approaches. Traditional studies in dialectology were generally aimed at describing the geographically distributed variation of language. However, with traditional approach, it would be difficult to analyze the complex reason for the changes in dialectal distributions. Since the geographical factor is not the only reason for language change, it is necessary to consider more factors in examining language maintenance and change. To investigate the distribution of dialects and explore its changes, the primary work involves thorough field surveys, and the next step is to draw a language map with well-organized dialect data. The present study employs a field survey method and draws a language map based on the field survey results. The purpose of this paper is to propose geolinguistic methodologies for analyzing the change in the distribution of dialects that can be confirmed on a language map constructed on such a basis. Geolinguistics analysis methods are as follows: 1) analysis by non-verbal conditions, 2) real time analysis, 3) measurement of innovation wave spreading speed, 4) surrounding-zones dialect theory, 5) principles of adjacent distribution and around distribution, and 6) S-curve theoretical analysis.

        A discourse on the Independence Hall of Korea, a representative cultural project of the 1980s, has been understood as a repetition of the traditional debate of the 1960s. It was considered as a petrified propaganda aimed at ensuring the fragile legitimacy of the military regime, and the architect as a sympathizer. Even if all these facts are true, it does not give any explanation for the architecture. Scrutinizing the building process and the change of discourse in the Independence Hall of Korea, this paper tries to explore a section of contemporary Korean architecture in the 1980s. The architect who designed the Independence Hall of Korea is Kim Kiwoong, however, it was Kim Won who took charge of overall scheme for it. Kim Won replaced the role of a technocrat in the 1960s, who deprived architects of his autonomy. Against this backdrop, Kim Kiwoong attempted to explain his own building via various concept like postmodernism, which gave him very proper context. But, later, he appropriated words like void and madang. These derived from some architectural historian’s researches in 1970s, and were to predict the architecture of the 1990s.

        Quality assessment of sweet persimmon or “Fuyu” was evaluated over room temperature distribution periods after 40-day storage at 0oC cold room. All Hunter’s values (L, a, and b) of sweet persimmon were significantly decreased after 4-day room temperature distribution while the flesh firmness was drastically decreased after 3-day room temperature distribution. Glucose and fructose contents were significantly increased by the degradation of sucrose after 3-day room temperature distribution. The highest extraction yield was obtained in the flesh of persimmon. Extraction yields of each part of “Fuyu” persimmon were 15.53% for flesh, 10.53 for seed, and 13.83 for flower bud. However, the total phenolic content of flesh was 4.8 μg/mg which was extremely lower than that of the seed (175.5 μg/ mg) and flower bud (178.2 μg/mg) of sweet persimmon. With high phenolic content, both the flower bud and seed of sweet persimmon showed excellent antioxidant activities by 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azinobis( 3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) free radical scavenging test. The results showed a great potential for byproducts (seed and flower bud) of long-term, cold-stored sweet persimmon “Fuyu” as a good antioxidant material for novel functional foods.

        The characteristics of temperature variation for laser diode welding system have been analyzed with numerical investigation. The laser diode is assembled with a cap and stem by projection welding. Resistance heat, in this process, is generated by electric current at the contact surface between cap and stem within a very short time. Temperature variation of laser diode is largely affected by the welding time and the heat generated from the surface. Maximum temperature of each component in the laser diode should be lower than the melting point except for cap and stem in order to prevent welding defect. Temperature distribution of each component in the laser diode is also affected by thermal conduction mechanism. Welding defect near the insulator occurs when the resistance heat is high. Appropriate resistance heat supply to the laser diode was about 400W. The results from this study could be applicable for optimal design of laser diode welding system.

        Recently the rapid changes of the social environment make both university and every each department should have to renovate and adjust all of the educational components. The most dominant and issuable change of business administration education is the Business Education Accreditation which was certified by the KABEA(Korean Association of Business Education Accreditation). And the only two department of fisheries business administration which in Gyeongsang National University and Pukyong National University has been accredited recently. Though The department of fisheries business administration in Korea has been influenced by that Accreditation, there is few research and analysis on educational change. So it is very important that research on the curricular constitution and change of the curriculum for considering the its own effect and influence. This paper aims to explore the curricular constitution, change and course fulfillment of fisheries business administration after the business education accreditation based on the case of the department of fisheries business administration in Gyeongsang National University. The analysis of fisheries business administration change will help develop sustainable curriculum and give more guideline for identifying the core of fisheries business administration. The method of analysing that in this research has adopt the social network analysis(SNA) and automated software tool which is the most dominant technique in contents analysis including the Krkwics and Pajek. The SNA is evaluated that most popular, rigorous and firm methodology for analyzing, examining and revising some concepts or objects in the context of semantics. The result of this study shows that the ratio of fisheries business administration class has been decreased but still the most fulfilled course. And English mediated class has been avoided though that sort of the class has been increased. In the view point of course fulfillment, it has been potential and inefficient problems that some classes that including financial related and accounting related class would not been accomplished appropriately. The findings of a graduate depth interview which has been done about 4 years for understanding that student show that there’s some recognition gap of fisheries business administration in staffs of human resource management. And the level of job satisfaction in fisheries business still somewhat low and even worse the chance of recruitment also unsteady.
