The aim of this study is to investigate the correlation between the support activities provided by the franchiser and how they affect the intention of the contract renewal and business performances made by franchisees, developing dynamic trust between these transactional partners. Various supportive activities between franchiser and franchisees were divided into financial and non-financial activities and dynamic trust into Transitional-based trust, Calculative-based trust, Relational-based trust, and Balanced-based trust. These trust types, which are variable and adjustable based on the opportunistic behaviors of business parties, were applied to define the impact of the support activities on the contract renewal intention and the performances. This study was developed around domestic franchisees. An investigator visited business owners and manager level-employees, explained the purpose of the survey prior to the response, and the answers were directly written by hands. A total of 348 copies were used for the analysis. As the results of the analysis, first, financial support activities were found to have a positive(+) effect on transitional-based trust, calculative-based trust, and balanced-based trust. On the other hand, non-financial support activities were found to have a positive(+) effect on calculative-based trust, relational-based trust, and balanced-based trust, and there was no significant relationship on transitional-based trust. Second, the dynamic trust had a statistically significant positive(+) effect on inducing the contract renewal. Lastly, in the relationship between the dynamic trust and its impact on business performances, only transitional-based trust, and relational-based trust were found to have a positive(+) effect on the financial performances. In addition, relational-based trust showed a meaningful positive(+) relationship on the non-financial performances, and non-financial performace showed a meaningful positive(+) relationship on the re-contract intention. From the results, it can be concluded that the financial and non-financial activities for a win-win partnership between franchiser and franchisees are essential in not only forming dynamic trust but also boosting business performances as well as maintaining the business relationship. Thus, it suggests that building a win-win partnership can be promoted more efficiently by specifying activities best suitable for a particular relationship. In addition, a specific set of activities could be presented for establishing the level of trust that is formed in situations that vary depending on transaction risks and interdependency arising from having the transactional relationship based on the contract as the franchise industry features. Eventually, it is expected that this study can provide a way to promote the qualitative improvement of the franchise industry by identifying factors essential to establishing a sustainable win-win system and relationships that can improve the business performance of franchisees.

In this study, reliabilities of holistic scoring method and analytic scoring method were analyzed in performance assessments of middle school students' science investigation activity. Reliabilities of 2, 3, and 4~7-level rubric ratings for analytic scoring methods were compared to figure out optimized numbers of rubric ratings. Two trained raters rated four activity sheets of 60 students by two rating methods and three kinds of rubric ratings. Internal consistency reliabilities of holistic scoring methods were higher than those of analytic scoring methods, while intrarater reliabilities of analytic scoring were higher than those of holistic scoring methods. Internal consistency reliabilities and intra-rater reliabilities of 3-level rubric rating showed similar patterns of 4~7-level rubric ratings. But students' discriminations, item difficulties and item-response curves showed that the 3-level rubric ratings was reliable. These results suggest that holistic scoring method could be adapted to increase internal consistency reliabilities with improvement in intra-rater reliabilities by rater's conferences. Also, the 3-level rubric rating would be enough for good reliability in case of adapting analytic scoring methods.

1990년 동북아 23개 지역의 이산화황 총배출량은 14.7백만톤이었다. 이중 중국동북부가 81%, 한국이 12%, 일본이 5%, 그리고 북한이 2%를 배출하였다. 기본시나리오하에서 동북아지역의 이산화황 배출은 2020년에 40.5백만톤에 이를 것으로 추정되고 있다. 중국에서 배출된 장거리 월경성 대기오염물질은 한반도와 일본으로 이동하며 특히 산성강우는 중국으로부터의 이산화황 배출에 크게 영향을 받고 있다. 산성강우는 자연생태계와 농작물에 피해를 줄 뿐 아니라 인간의 건강에도 심각한 피해를 준다. 따라서 미래의 산성강우 피해를 줄이기 위해서는 자국뿐 아니라 인접국의 이산화황 및 질소산화물 배출도 함께 감소되어야 한다. 동북아지역 국가들은 경제발전단계 및 환경협력 논의에서의 우선순위가 다르기 때문에 가까운 시일내에 환경협력을 위한 다자간 협약을 체결하기는 어려울 것이다. 따라서 ESCAP, APEC 등 기존의 지역협력기구를 이용하거나 IBRD, ADB 등의 다자간 외부금융기관이나 공적개발원조 (ODA) 등을 통해 개선된 환경기준을 준수하도록 하고 지역환경개선을 위한 협력사업을 추진하는 것이 바람직하다. 또한 산성비와 관련한 동북아 환경협력은 과학적 조사를 통해 객관적이고 신뢰할만한 정보를 획득하는 것으로부터 시작하여 단계적으로 추진되어야 하며, 정치, 경제, 과학, 외교 등 여러 분야에 걸쳐 중앙정부 뿐만 아니라 지방정부와 NGO도 포함하는 다차원적, 포괄적으로 추진되어야 한다.

A tactile sensor employs a piezoelectric element to detect contact frequency shifts and thereby measure the stiffness or softness of material such as tissue, which allows the sensor to be used in many fields of research for urology, cardiology, gynecology, sports medicine and caner detection and especially for cosmetics and skin care. In this study, reliability of the tactile sensor system was investigated with its manual application to the muscles susceptible to temporomandibular disorders. Stiffness and elasticity of anterior temporalis, masseter and trapezius muscles were calibrated bilaterally from 5 healthy men with an average of 24.5$\pm$0.94 years. The tactile sensor used in this study had a computer-controlled and motor-driven sensor unit which automatically pressed down on the skin surface over the muscles being measured and retracted, thereby providing the hysteresis curve. The slope of the tangent of the hysteresis curve (${\Delta}f/{\Delta}x$) is defined as stiffness of the muscle being measured and the distance between the two parts of the curve as its elasticity. To determine inter-examiner reliability, all the measurements were performed by the two examiners A and B, respectively and the same examination were repeated with an interval of 2 days for intra-examiner reliability. The results from this study demonstrated high reliability in measuring stiffness and elasticity of anterior temporalis, masseter and upper trapezius muscles using a tactile sensor system. It is suggested that the tactile sensor system can be a highly reproducible and effective instrument for quantitative evaluation of the muscle in head and neck region.

Objective : This study aimed to develop a Comprehensive Oro-Facial Function Scale (COFFS) that can evaluate oro-facial function in patients with dysphagia. Methods : To verify the item composition and reliability of the COFFS, preliminary items were collected by selecting and analyzing four previous studies, and the Content Validity Ratio (CVR) was derived through a second survey of experts. Cronbach's 𝛼 was calculated for the internal validity of the evaluation items, and the test-retest reliability and inter-rater reliability were calculated using the internal classification coefficients (ICC). Results : The content validity ratio of all items was 0.67; in the case of Cronbach's 𝛼 value for each domain, 0.849 for communication domain, -0.224 for the oro-facial structure and shape, 0.831 for the ability to perform orofacial movements, and 0.946 for mastication and swallowing function. The test-retest reliability was 0.974 and the inter-rater reliability was 0.937, showing high reliability. Conclusion : In this study, the evaluation tool of COFFS was finally selected from 34 items in four areas and developed on a 3-5 point scale according to the evaluation items. In future studies, additional research is needed to prove its validity through correlation with other evaluation tools that measure oro-facial function.

The purpose of the study was to develop the home fall prevention checklist for community-dwelling older adults. And the validity and reliability of the checklist were tested. The preliminary questions were developed through content validity by twenty experts using the CVI(Content Validity Index). Following the establishment of content validity, 52 items of the checklist were developed. Responses of 299 community-dwelling older adults were analyzed to further establish both reliability and validity of the checklist. Reliability using cohen's kappa coefficient and test-retest reliability(rate of concordance(%)), and construct validity using known-group comparison technique were tested. 51 items were over 0.80 in the cohen's kappa coefficient of the checklist, 45 items were over 80.0% in test-retest reliability. Construct validity was established by known-group comparison(t=3.50, p=.001). Validity and reliability of the checklist were confirmed. This checklist will help further studies to develop more safe environment to prevent falls.

The purpose of this study is to develop an assessment tool to evaluate student character competence in applying a Collaborative Problem-Solving Instruction Model in science education. Through the literature analysis, nine elements of character are extracted. They are: openness, empathy, tolerance, caring, integrity, self-regulation, honesty, responsibility, and cooperation. Based on these existing measures of character competence, experts discussed and developed items for evaluation of a student's character competence based on the Collaborative Problem-Solving Instruction Model. The first 88 preliminary items were investigated, corrected, and supplemented based on the results of the first survey. A second validity survey was conducted on 71 middle- and high school science teachers to determine the content validity of the items. Inter-rater reliability was calculated for the assessors to verify the reliability of the items. Overall, the inter-rater reliability and content validity of the assessment items are good with 53 items ultimately being selected based on the analysis results. The assessment tool developed in this study could be used to explore changes in student character competence through a Collaborative Problem-Solving Instruction Model, as well as to evaluate student character competence in science education.
