The paradigm of the corporate innovations has been changed from the intra-company innovations to the inter-company innovations. A prevalent approach to the inter-company innovations is the supply chain management. Three key words of the core concept of supply chain management are the long-term relationship, resource integration, and value creation. Specifically, it means that the supply chain management aims to make value creation through the resource integration for the supply chain entities, based on the long-term relationship between buyers and sellers. To make more effective long-term relationship among the supply chain entities, it is very important for the supply chain entities to analyze followings: i) What variables can influence the long-term relationship, ii) How these variables can influence to the long-term relationship. However, previous researches mostly deals the long-term relationship in the marketing area in fragment, and thus few research efforts have been done for the development of conceptual model using supply chain management theories. In contrast to previous studies, our research tried to develop and examine the integrative research model by introducing both the marketing theories and the supply chain management theories, and thus related hypotheses are derived. A multiple regression analysis was performed to examine the influence of the antecedents of the long-term relationship, for the 87 retailers of grocery supply chains. The empirical results confirm that cultural similarity, reputation, interdependency, and trust positively influence long-term relationship (i.e., partnership orientation and partnership symmetry). And results also confirm that the supply implementation factors such as organization integration, information system integration, and process integration playa moderating role between antecedents and long-term relationship. These findings suggest that companies should perceive the importance of managing the process, organization, information system integration in the long-term relationship implementation process as well as the factors such as cultural similarity, reputation, interdependency, and trust in the long-term relationship establishment process.

The paper presents a finite element model for studying timber-concrete composite beams under long-term loading. Both deformability of connection system and rheological behaviour of concrete, timber and connection are fully considered. The creep of component materials and the influence of moisture content on the creep of timber and connection, the so-called "mechano-sorptive" effect, are evaluated by means of accurate linear models. The solution is obtained by applying an effective step-by-step procedure in time, which does not require storing the whole stress history in some points in order to account for the creep behaviour. Hence the proposed method is suitable for analyses of composite beams subjected to complex loading and thermo-hygrometric histories. The possibility to accurately predict the long-term response is then shown by comparing numerical and experimental results for different tests.

Before introducing the national long-term care insurance in 2008, the want for long term care service has to be estimated and analysed. This study estimates the demand and analyses what determines the want of long term care service. This study investigated data of 3f6 elderlies, that was collected by age stratified random sampling. The elderies resided in Onyang 4 - dong (urban area) and Dogo-myun (rural area) In the city of Asan. The researchers visited the elderlies and their care giver, and assessed their demand for the long term care service and examined physical, mental, socio-economic status by the assessment tools for Korean Long-Term Care System. $64\%$ of the those who are entitled to be served refuse the long term care service. $26.7\%$ of them wants for home care service and $7.9\%$ want facility care service. It is estimated that the want of home care service are three or four times as much as that of facility care service. The demand for long term care service is 5.155 times higher for those who live in rural area (p=0.000), 3.040 times higher for those who do not have spouse(p=0.057), and 3.356 times higher for the people who is in medicaid than medical insurance(p=0.029). However, income(p=0.782), means(p=0.614), living alone(p=0.223), number of family to live with (p=0.341) and age of the elderly(p=0.420) are not related with the demand of long term care service. The assessment tools for Korean Long-Term Care System for need evaluation of the long term care service can reflect the demand well.(p=0.024) If medical care will cover $80\%$ of total cost, the willingness to pay of the out of pocket money of the people with medical insurance is 67,400 Korean Won(66.77 US$) for the home care service and 182,500 Korean Won(180.78 US$) for the facility care service. There is possibility that long term care demand is still small after Introducing the long term care Insurance due to the care given by family members. When developing service delivery system of long term care insurance, rural area has to be given more consideration than urban area because of the higher demand. The people who do not have spouse or are in medicaid have to be given special consideration as well.

We studied simultaneously the electronically written data affected in the use of thermal transfer discs and the recoding strategy between recoding drives for the stable long term preservation of optical discs which are commonly used in an electronic data storage device. The most important thing in the archiving preservation might be a choice of a device, however the use of thermal transfer recording discs is not good for long term data preservation because the thermal effect on the recoding data is critical which means that the data are recorded not under best condition but under bad condition. We inspect the strategies of recoding data from 12 brands of optical discs and drives of 7 brands and it turns out the recoding strategy is needed first for the long term preservation of electronic recording data. Thus, without affecting data quality and deformation of optical discs, the choice of optimal disc and drive in recoding data will be a solution for the long term preservation of recoding data.

One-year-long groundwater-level data have been collected from 18 wells in Cheon-an area. The result of barometric efficiency, autocorrelation, cross-correlation and statistical distribution evaluated from the measurement data shows that groundwater-level measurements from observation wells are the principal source of information about aquifer characteristics. Data from WA-2 has high barometric efficiency as well as steady decreasing auto-correlation coefficient, which means nonleaky confined aquifer, Most aquifers in this study show the unconfined properties so that barometric efficiencies are mostly low and the coefficients of cross-correlation between groundwater-level and precipitation are commonly high. This study showed that the long-term groundwater-level monitoring data without artificial stress such as pumping would give accurate information about aquifer characteristics.

이 논문은 분수공적분 개념을 이용하여 KOSPI200지수와 지수선물가격간에 장기균형관계가 있는지를 살펴보고 있다. 이것을 위해 로그변환 현 선물가격 각각의 분수차분계수를 주파수영역 (frequency domain)의 GPH 추정량을 구한 다음, 현 선물 회귀식의 추정을 통해 도출한 균형오차의 차분계수와 비교하였다. 이 방법은 전통적인 공적분방법에서 규명하지 못한 금융시계열자료의 통계적인 특성을 분석할 수 있는 장점이 있다. 분석결과를 요약하면 다음과 같다. 첫째, 정수차원의 차분구조모형에서는 공적분검정을 통한 장기균형관계의 증거를 찾기가 어려웠다. ADF 단위근 검정과 KPSS 정상성 검정에서 상반된 결과가 제시되어 두 시계열을 I(1)으로 확정하기가 불가능하였다. 둘째, GPH 추정량를 이용하여 차분계수를 추정한 결과, 두 시계열 모두 불안정한 장기기억구조를 가지는 것으로 식별되었고 균형오차는 정상적인(stationary) 장기기억구조를 가져 현 선물가격간에 분수공적분관계가 있는 것으로 파악되었다. 이 논문은 선물시장과 현물시장이 장기균형관계를 국내 선행연구에서 이용하지 않았던 분수공적분을 이용하여 분석했다는 점에서 그 의의를 찾을 수 있다.

The purpose of this study is to monitor the long-term vegetation change of the village complementary forest after restoration. Based on the monitoring in 2010, six years after the restoration project in 2004, the monitoring of the complementary forest in Dubang village in 2019 after 9 years was conducted. This study identifies the change of species diversity and structure, growth, vegetation coverage, structural quality etc. and succession through long-term monitoring. For this, field survey was conducted in 2003 and 2010, 2019. The results demonstrate significant increase of species diversity and multi-layer structure and progress of natural succession. Overall, Part I is considered to be a quasi-natural complementary village forest, which has a natural balance between natural vegetation that have remained in nature for a long time and anthropogenic vegetation, revealing the coexistence of nature and humanity. It means ecological structure and function have improved. Part II should be restored to the lost part and adaptive management rather than excessive management should be carried out to leave natural succession.
