Purpose - This study aims to determine the effects of marketing factors on the long-term purchasing behavior regarding industrial goods, using data from wholesalers and retailers. Research design, data, and methodology - We used multiple regression analysis and 3-step regressions to investigate causality. We used 177 questionnaires targeting wholesalers and retailers of industrial goods. Results - First, long-term purchasing behavior is positively related only with advertising and marketing factors. Second, the relationship between marketing factors and brand value show that the physical environment, word-of-mouth advertising, and publicity are positively related, except advertising and sales promotion, respectively. Third, brand value and long-term purchasing behavior are positively related. Finally, brand value is not a mediator between marketing factors and long-term purchasing behavior. Conclusion - This study suggests that industrial goods providers should use marketing strategies that are different from those used in the consumer market. Further, if they want to maintain long-term relationships, they should increase their brand value.

Purpose: This study was to analyze the factors that affect the service relationship of long term care workers for the elderly and to provide basic resource for the successful connection of long term care services. Methods: 259 subjects who were engaged in long term care units completed a self-administered questionnaire that measured the extent of service linkage among one another. The Cronbach's ${\alpha}$ score determined the internal consistency of the acquired data and the discriminated validity was estimated by Pearson's correlation coefficient. Multiple regression analysis was conducted to investigate the influence of the known factors on the service linkage. Results: Acceptance and participation negatively influenced on the service linkage. Reliance, comprehension, recognition on service, and frequent contact with others positively activated the service linkage of long term care workers. Conclusion: The establishments of systemic training courses providing education that emphasizes reliability and recognizes other services, including work environment to contact easily are needed to improve the service-linkage of long-term care workers for the elderly.

The study assesses the impact of trade liberalization factors on changes in customs revenues in Vietnam. Research data was conducted between 2002 and 2017 on the official website of the Government's Web Portal and The World Bank. This paper uses the vector error correction model to estimate the short-term and long term relationship between data series. The results have proven that tariff reductions have a positive effect on short-term and long-term customs revenues in Vietnam. However, the implementation of other international commitments on trade liberalization has positive short-term and long-term negative impacts on customs revenues in Vietnam. The study's results also show that exchange rate has no effect on changes in customs revenues in the short term but it has a strong impact on increasing customs revenues in the long run. Based on these findings, the article also suggests a number of policies to ensure customs revenues in Vietnam in future. In order to ensure customs revenues, the government of Vietnam should: (1) having some policy to improve the efficiency of customs management in Vietnam; (2) Building appropriate VND exchange rate policy; (3) Establishing reasonable non - tariff barriers to prevent fraud and ovations cause losses in customs revenues.

The importance of university technology transfer has widely been brought to the center of attention over the last decades. Research and practice thereby often concentrate on issues related to patenting and licensing or entrepreneurship but abstract away from relationship- and network-focused initiatives. In this paper, we argue that efforts to systematically develop close, long-term collaboration partnerships - although complex and resource intensive - are likely to be more beneficial for both universities and industry in the long run. Drawing on data derived from interviews with technology transfer executives of 22 leading European and U.S. universities, we analyze and discuss well-established practices of network and relationship management and their possible impact on technology transfer success. Our findings indicate that dedicated relationship management approaches can yield a sustainable competitive advantage for universities. We thereby shift the focus away from transaction-orientation towards more forward-looking relationship-centric approaches and discuss their institutionalization in great detail.

Dental hygienists are important members of any dental clinic. They are recognized as reflecting the dental clinic's image because they spend a lot of time with patients. The longer the dental hygienist is employed, the better the relationship with the patients and the medical service provided. The purpose of the present study was to develop a scale to measure factors of long-term employment among dental hygienists. The basic questions were constructed by analyzing tools used to measure job embeddedness and satisfaction. Forty-one questions were developed that measured organizational fit (13), interpersonal relationships (8), job satisfaction (7), duty satisfaction (6), recognition (4), and self-esteem (3). A questionnaire survey was conducted, and the responses from 297 dental hygienists in dental clinics, after the exclusion of 20 incomplete surveys, were used for the exploratory and confirmatory factor analyses. As revealed by exploratory factor analysis, long-term employment intention was composed of 7 factors consisting of 29 items after the exclusion of 12. The subsequent confirmatory factor analysis revealed 4 factors ("organizational fit," "professional identity," "job connectivity," and "interpersonal relationship") consisting of 16 items, after the exclusion of 13. $Cronbach^{\prime}s\;{\alpha}$ were 0806, 0.836, 0.700, and 0.684 for the four factors. This study is meaningful in that it developed a long-term employment factor measurement tool that can be applied to domestic dental hygienists. Future studies will need to focus more on professional identity and job outcomes. The results of this study and future related ones could be used to improve dental hygienist's continuous service.

Background: Red blood cell (RBC) transfusion improves cardiorespiratory status of preterm infants by increasing circulating hemoglobin, improving tissue oxygenation, and reducing cardiac output. However, RBC transfusion itself has also been suggested to negatively affect short-term outcomes such as intraventricular hemorrhage (IVH), bronchopulmonary dysplasia (BPD), retinopathy of prematurity (ROP), and necrotizing enterocolitis (NEC) in premature infants. Purpose: This study aimed to analyze the relationship between RBC transfusion and short-term outcomes in very low birth weight (VLBW) infants (birth weight, <1,500 g). Methods: We retrospectively reviewed the medical records of VLBW infants admitted to the Soonchunhyang University Bucheon Hospital between October 2010 and December 2017. Infants who died during hospitalization were excluded. The infants were divided into 2 groups according to RBC transfusion status. We investigated the relationship between RBC transfusion and short-term outcomes including BPD, ROP, NEC, and IVH. Results: Of the 250 enrolled VLBW infants, 109 (43.6%) underwent transfusion. Univariate analysis revealed that all short-term outcomes except early-onset sepsis and patent ductus arteriosus were associated with RBC transfusion. In multivariate analysis adjusted for gestational age, birth weight and Apgar score at 1 minute, RBC transfusion was significantly correlated with BPD (odds ratio [OR], 5.42; P<0.001) and NEC (OR, 3.40; P= 0.009). Conclusion: RBC transfusion is significantly associated with adverse clinical outcomes such as NEC and BPD in VLBW infants. Careful consideration of the patient's clinical condition and appropriate guidelines is required before administration of RBC transfusions.

Long-term trend analysis on air pollutant concentrations is very important to diagnose the present status and plan for the future. In this study, the long-term trends of $PM_{2.5}$ concentrations were estimated based on the relationship between the visibility and $PM_{2.5}$ concentration regarding the effects of relative humidity in Seoul and Chuncheon. The relationships between the visibility and $PM_{2.5}$ concentration were derived from the measurement data in 2015 and 2016. Then, the annual trends of $PM_{2.5}$ concentration from 1982 to 2014 were estimated and compared to those of $PM_{10}$ concentration available in Seoul and Chuncheon. During the estimation process, four ranges of relative humidity were considered such as less than 30%, 31~50%, 51~70%, and 71~90%. In Seoul and Chuncheon, the visibility and $PM_{2.5}$ concentration generally have the inverse relationship while the visibility decreases as the relative humidity increases. The estimated $PM_{2.5}$ concentrations similarly showed the decreasing tendencies from 2006 to 2012 in Seoul and Chuncheon. However, the estimated $PM_{2.5}$ concentrations showed the increasing tendency before 2005 in Chuncheon in contrast to the decreasing tendency in Seoul. This implies that the long-term trends of $PM_{2.5}$ concentration in different cities in South Korea reflect the local influencing factors. For example, 'Special Act on the Improvement of Atmospheric Environment in the Seoul Metropolitan Area' can affect the different long-term trends in Seoul and Chuncheon. The estimated $PM_{2.5}$ concentrations were validated with the measured ones in Seoul and Chuncheon. While the general tendencies were well matched between the estimated and measured concentrations, the $PM_{2.5}$ concentration trends in 1990s and their monthly variations are needed to be improved quantitatively using more reference data for longer years.

The care market has a unique characteristic that cannot be understood only by pure consumerism. It is not simply constituted by the relationship between consumers and providers at a uni-dimensional level of consumerism logic; rather, it operates in the tripartite-dimensional relationship between the state, consumers and providers through the design and regulation of policies by the state(Evers 1994). The unit costs of long-term care insurance has a meaning as the signal of state for policy direction. This paper consists three contents. The first, it provides to examine the developing process and method of the unit costs of long-term care and to define the characteristics of the developing method of unit costs of the Korean Long term care Insurance. The second, it tried to evaluate the adequacy, validity, and equity of unit costs of care. The third, it proposed the policy direction and measures focused on state's role as price determinator and regulator of care market in that unit costs of care is very important factors for formation and operating of care market.

For a long cable-stayed bridge, stay cables are its most important load-carrying components. In this paper, long-term monitoring of super-long stay cables of Sutong Bridge is introduced. A comprehensive data analysis procedure is presented, in which time domain and frequency domain based analyses are carried out. In time domain, the vibration data of several long stay cables are firstly analyzed and the standard deviation of the acceleration of stay cables, and its variation with time are obtained, as well as the relationship between in-plane vibration and out-plane vibration. Meanwhile, some vibrations such as wind and rain induced vibration are detected. Through frequency domain analysis, the basic frequencies of the stay cables are identified. Furthermore, the axial forces and their statistical parameters are acquired. To investigate the vibration deflection, an FFT-based decomposition method is used to get the modal deflection. In the end, the relationship between the vibration amplitude of stay cables and the wind speed is investigated based on correlation analysis. Through the adopted procedure, some structural parameters of the stay cables have been derived, which can be used for evaluating the component performance and corresponding management of stay cables.

This study is to investigate the effect of real exchange rate on bilateral trade balance between Korea and ASEAN 10 countries. Using quarterly data from 1991 to 2017 the paper analyzes whether or not the real depreciation of Korea's won could improve the trade balance in the short and long term. Based on Autoregressive Distributed Lag(ARDL) model, the empirical results show that trade balance, GDP, and real exchange rate are all cointegrated, representing the long-run relationship among variables. In the consideration of long-run relationship, the increases in ASEAN countries' GDP could have a negative impact and Korea's GDP positive impact on trade balance between Korea and ASEAN countries unexpectedly. For the main variable, the paper did not find the long-term effect of real exchange rate on the trade balance, for the short-term effect of the real exchange rate it was found that there exists the J-curve effect only in the case of Vietnam and Brunei. Therefore, these results imply that the intended policy concerning the exchange rate in the free-floating exchange rate system could be limited to improve the trade balance between Korea and ASEAN countries.
