This purpose of this study is to analyze the causal relation among constituent concepts and verify the relation among internal marketing, service quality and customer satisfaction in shipping companies. To achieve the goal of this study, the author studied literatures on internal marketing, service quality and customer satisfaction, and carried out a survey targeting people working for shipping companies and international logistics freight forwarders to make an empirical analysis. The results are as follows. It was confirmed that education and training, reward system, empowerment among internal marketing elements of a shipping company have a positive effect on the service quality and customer satisfaction of the shipping company, and the service quality of a shipping company also has a positive effect on customer satisfaction. As it can be known from these results, it would be necessary to concentrate on internal marketing of a shipping company in order to increase service quality and customer satisfaction.

Many plutonic rock fragments of granitic composition were collected from the Deception Island. We obtained K-Ar ages of $62.5{\pm}1.2\;Ma$ and $140.7{\pm}2.7\;Ma$ from the two samples. Such result contradicts the general belief that most of the volcanic rocks of Deception Island are products of very recent activities and their maximum age does not exceed 200 ka. On the other hand, Mesozoic to Cenozoic rocks produced by subduction-related active magmatism have been reported from both South Shetland Islands and Antarctic Peninsula, located to the north and south of the Deception Island respectively. Also, various kinds of plutonic rocks with granitic composition are distributed widely. Therefore, plutonic rock fragments with granitic composition discovered from the Deception Island seem to indicate their derivation by capturing granitic crustal material underlying volcanic edifice during the volcanic activities, instead of differentiation from magmas related with recent volcanism. Ages and rock types of the plutonic rock fragments suggest arc-related origin just as adjacent South Shetland Islands and Antarctic Peninasula.

The entry of large discount stores such as E-mart, LG mart, Magnet etc. into small cities have had a profound impact on the business of small-sized retailers. Now, it becomes the matter of survival for small-sized retailers and it is almost impossible to reverse those trends. Without satisfying consumers' various needs and wants, retailers can not survive. Therefore, it is extremely important to understand retail competition from the perspective of consumers in order for retailers to survive in the turbulent environment. The previous research studies on retail competition have focused on the comparison among different types of retailers with respect to strategic retail mix variables. However, they do not consider the competitive aspects of consumers' sides. In addition, we do not fully understand the meaning of "shopping." Shopping means hedonic shopping as well as utilitarian shopping. Utilitarian aspects are important but consumers also prefer' hedonic aspects too. That is the reason that traditional retailers such as small-sized retailers can not compete with modem and large retailers. We use three different methods to identify the macro and competitive structure. of retailing with respect to shopping. Factor analysis, multidimensional scaling, and multiple correspondence analysis are used to produce perceptual mapping of retail competition. Department store and large discount store are identified as close competitors but both might have an indirect impact on small-sized retailers through demand shift toward high end retailers.

Andesitic pyroclastics and lava flows are deposited as a part of composite volcanoes by Cretaceous volcanic activity in Geojae Island, off the coast of Korea. The andesitic pyroclastics are composed of tuff breccia and lapilli tuff minor intercalated tuff. Lava flows are divided into dense and porphyritic andesite containing phenocrysts of plagioclase, pyroxene, and/or hornblende. The andesitic rocks represent charactersitcs of carc-alkaline BAR association with basalt, basaltic andesite, andesite, and dacite to rhyolite. Major element variations of the volcanic rocks show that $Al_2O_3$, total FeO, CaO, MgO and $TiO_2$ decrease with increasing $SiO_2$ but $K_2O$ and total alkalis increase, and represent differntiation trend of calc-alkaline rock series. In spider diagram, contents of Sr, K, Rb, Ba, and Th are relatively high, but contents of Nb, P, Ti and Cr are low. These petrochemcial characteristics are similar to those of rocks from island arc or continental margein related to plate subduction. Chondrite-normalized REE patterns of volcanic rocks are paralle to subparallel, with LREE enriched than HREE, and show gradual increase of negative Eu anomaly from basalt to dacite and rhyolite, suggesting comagmatic fractional crystallization with minor effects of assimilation and magma mixing. Andesitic rocks are assumed medium-K orogenic andesites that formed in the tectomagmatic environment of subduction zone under normal continental margin arc.

The purpose of this study was to explore ways to help reduce adolescents' academic stress by exploring the influences of parental learning involvement and family strengths on academic stress. The research participants were 445 middle school students living in Gwangju. Data were collected from self-reported questionnaires and analyzed with SPSS 23.0 program. The major findings were as follows: First, the parental learning involvement(provision of learning option, democratic rules, encouragement of academic progress) and academic stress showed significant differences according to gender. There was a significant difference in academic stress depending on school year, but there was no significant difference in parental learning involvement. The family strengths did not show significant difference according to gender or school year. The parental learning involvement(provision of learning option, democratic rules, pursuit of adequate performance, academic information, total), family strengths, and academic stress showed significant differences according to economic status. Second, the adolescents' academic stress was influenced by parental learning involvement(encouragement of academic progress, democratic rules, pursuit of adequate performance) and family strengths. Approximately 30 percent of the adolescents' academic stress was explained by these variables.

In this paper, we investigate the geochemical and isotope properties of the Jeongeup foliated granite (hereafter, the JFG) in the Jeongeup area, aiming at establishing the movement age of the Honam shear zone by U-Pb sphene geochronology. In the AMF diagram, the JFG corresponds to the calc alkalic rock series, and belongs to the magnesia region in the diagram of silica versus $FeO^{total}/(FeO^{total}+MgO)$. Additionally, in the Rb-Ba-Sr diagram, it is classified as granodiorite and anomalous granite with distinctive negative Eu-anomaly in the REE patterns. According to the silica and trace element contents, the JFG falls on the type VAG+syn-COLG, which implies that this was formed under the circumstance of compressional continental margin or volcanic arc. $^{143}Nd/^{144}Nd$ isotope ratios range from 0.511495 to 0.511783 and $T_{DM}$ are calculated to be about $1.68{\sim}2.36Ga$. U-Pb sphene ages of the JFG are $172.9{\pm}1.7Ma$ and $170.7{\pm}2.8Ma$, based on $^{238}U-^{206}Pb$ and $^{235}U-^{207}Pb$ ages, respectively. Presumably, the dextral ductile shearing in the Jeongeup area has occurred after 173 Ma.

IT system in supply chain management(hereafter, SCM) has been regarded as one of competitive advantage to win over competing supply chain. SCM participants rush to adopt IT system to be agile for changing environment. Companies expect the improvement of the process integration over the supply chain, which enhance the overall SCM performance. IT system has been considered to influence on effective communication over the wall of firm boundaries. But, the profitability or the effectiveness of IT investment are controversial. This study try to reemphasize the importance of IT system considering the differences of processes, and the influences on the collaboration of supply chain participants. We want to know the perception level of functional managers for the importances, usages, and contributions of IT system in manufacturing sector. Also, we compare the different perception for collaborative SCM among supplier, buyer, and employees of buyer, and try to understand the context in which the IT investment acceptance occurs. We collected 297 responses(199 from line process and 98 from project process respectively). Results show that the importances, usages, and contributions of IT system are higher in the line process than in the project process.

임진강대의 변성이질암은 전형적인 바로비안형 변성분대를 보이며, 남쪽으로 갈수록 변성도가 증가하여 석류석$\longrightarrow$십자석$\longrightarrow$남정석 대를 정의한다. 우리는 반상변정의 성장과 여러번에 걸친 광역변형작용의 연관성을 밝히기 위해 광물의 반응관계와 성장순서 그리고 미구조(microstructure)를 -특히 석류석에 대해서- 연구하였다. 임진강대는 크게 세 번에 걸쳐 변형작용을 받은 것으로 해석된다: (1) 지각 두께의 증가에 수반된 압축변형작용 (D$_{n-1}$), (2) 주 엽리(Sn)를 만든 변형작용(Dn), 그리고 (3) 연성전단작용에 수반된 신장변형작용(D$_{n+1}$ ). 석류석대의 석류석 반상변정에서는 약간 휘어진 포유물 궤적(inclusion trail)이 주 엽리면에 대해 연속적이며, 이는 Dn과 동시기에 반상변정이 생성되었음을 지시한다. 이러한 석류석은 녹니석과 백운모로 구성된 주 엽리를 치환하면서 자라기 때문에, 녹니석+백운모+석영=석류석+흑운모+$H_2O$의 반응에 의해 만들어진 것으로 해석된다. 석류석 자형변정(idioblast)이 주 엽리를 자르면서 성장하기도 하는데, 이는 Dn 이후에도 석류석이 후구조(post-tectonic) 광물로 성장했음을 지시한다. 또한, 이러한 석류석은 흑운모를 치환하기 때문에, 동구조(syn-tectonic) 석류석의 생성반응에서와는 달리 흑운모가 반응물임을 알 수 있다. 한편, 십자석대의 석류석은 포유물 궤적에 의해 정의되는 S$_{n-1}$면이 주 엽리면과 사각을 이루며 단속적이기 때문에, D$_{n-1}$과 Dn 사이에 자란 것으로 해석된다. 이와는 대조적으로 십자석은 주 엽리를 치환하면서 자라고 있어서 Dn과 동시기 혹은 Dn 이후에 자랐을 것으로 해석된다..의 환경문제를 발생하지 않으며, 공정액에 첨가제를 투입하지 않으므로 순환형 친환경공정으로 각광받을 수 있다. 본 연구에서는 고온, 고농도의 NaOH 수용액의 처리에 적합한 막소재와 발생될 수 있는 제반 문제점 등을 파악하였고, 장기간의 실험을 거쳐 최적 투과 압력(Trans membrane pressue), 세정 조건 및 주기, 막재질에 있어서 보강하여야 할 Point, 최적 운전 조건들을 토출해 내었고, 향후 실제 Plant에 적용할 계획이다.는 양적으로 다른 두 가지의 유사한 마그마가 수반된 것으로 추정된다. 것으로 추정된다.를 사용하지 않음으로써 효과적이고 만족할 만한 심근보호 효과를 보였다.를 보였다.4주까지에서는 비교적 폐포는 정상적 구조를 유지하면서 부분적으로 소폐동맥 중막의 비후와 간질에 호산구 침윤의 소견이 특징적으로 관찰되었다. 결론: 분리 폐 관류는 정맥주입 방법에 비해 고농도의 cisplatin 투여로 인한 다른 장기에서의 농도 증가 없이 폐 조직에 약 50배 정도의 고농도 cisplatin을 투여할 수 있었으며, 또한 분리 폐 관류 시 cisplatin에 의한 직접적 폐 독성은 발견되지 않았다이 낮았으나 통계학적 의의는 없었다[10.0%(4/40) : 8.2%(20/244), p>0.05]. 결론: 비디오흉강경술에서 재발을 낮추기 위해 수술시 폐야 전체를 관찰하여 존재하는 폐기포를 놓치지 않는 것이 중요하며, 폐기포를 확인하지 못한 경우와 이차성 자연기흉에 대해서는 흉막유착술에 더 세심한 주의가 필요하다는 것을 확인하였다. 비디오흉강경수술은 통증이 적고, 입원기간이 짧고, 사회로의 복귀가 빠르며, 고위험군에 적용할 수 있고, 무엇보다도 미용상의 이점이 크다는 면에서 자연기흉에 대해 유용한 치료방법임에는 틀림이 없으나 개흉술에 비해 재발율이 높고 비용이 비싸다는 문제가 제기되고 있는 만큼 더 세심한 주의와 장기 추적관찰이 필요하리라 사료된다.전 도부타민 심초음파는 관상동맥우회로술 후

This study aimed (a) to examine the association between chronic illness and multidimensional disability(i.e., psychological/emotional functions, activity capacity, and participation frequency) among older adults with disabilities, (b) to investigate the effect of formal and informal supports on multidimensional disability, and (c) to analyze the moderating effects of formal and informal supports on the association between chronic illness and multidimensional disability. This study used 2014 Korea Welfare Panel Study(the 9th wave) data and 450 older adults with disabilities aged 50 and over were selected as the study target. The research model was analyzed by structural equation modeling using IBM AMOS 22.0. Based on the ICF framework developed by WHO, health condition was measured by the level of chronic illness; psychological/emotional functions were measured by health satisfaction, self-esteem, and depression; activity capacity was measured by ADLs and IADLs; participation frequency was measured by the total number of social activities joined; formal support was measured by the total number of formal welfare services for people with disabilities utilized; informal support was measured by perceived social support. The findings showed that the level of chronic illness was negatively associated with psychological/emotional functions among the older adults with disabilities. The informal support positively affected psychological/emotional functions and activity capacity, whereas the formal support showed the opposite result. That is, the formal support negatively influenced activity capacity and showed a moderating effect on the association between the level of chronic illness and the psychological/emotional functions in a reverse way. Based on the results, practice and policy implications for alleviating disability level among the older adults with disabilities were discussed.
