Purpose - Goal setting is effective in any domain in which an individual or group has some control over the outcomes. It applies not only to work tasks but also to sports and health, and in various other settings. Its success depends on considering the mediators and moderators determining its efficacy and applicability. This study investigates the individual factors influencing academic goal attainability. Unlike previous studies, we focused on the effect of the relationships between individual traits (passion, tenacity, self-control) and specific motivation (vision, self-efficacy, implementation intentions) with academic goal attainability, rather than the effects of the relationship between commitment and the goal shielding mechanism with goal attainability. Research design, data, and methodology - Data collected through questionnaires were analyzed by the SPSS program. A total of 293 school students, who participated in the TOEIC program, participated in the survey. Slightly more than half were female (male: n=145 vs. female: n=148). We verified nine hypotheses through various statistical methods (reliability analysis, exploratory factor analysis, confirmatory factor analysis, structural equation model for the hypothesis test, bootstrapping test for the mediation test). Results - Data was analyzed in three phases. The first phase involved measurement analysis (i.e., item purification and factor structure confirmation), involving the scales of the three variables of individual traits, three mechanism variables, and goal attainability. The second phase involved estimating the proposed structural relationships among the key constructs (see Figure 1), using the results to test H1 to H9. The final phase involved examining the mediating effects of the three variables (vision, implementation intention, and self-efficacy). The research model shows that the independent variable passion has a significant result with both the mediators-vision and self-efficacy. Further, vision and self-efficacy significantly affect goal attainability. The second variable, self-control, shows a significant effect when mediated by implementation intentions, but the direct relationship between implementation intension and goal attainability shows an insignificant result. However, when further mediated by self-efficacy, it showed a significant effect between self-efficacy and goal attainability. Similarly, the third variable, tenacity, shows an insignificant result when mediated by vision. In contrast, the mediator self-efficacy shows a positive effect between tenacity and goal attainability. Conclusions - This study shows how these individual traits, when mediated with the appropriate motivational factors, resulted significantly in the attainability of academic goals. We may identify several theoretical and practical contributions. Theoretically, we developed a step further in the research into consumer goals and related studies. Future research could examine the effects of different learning goal types and their combinations with performance goals (e.g., learning goals first, then performance goals), different types of goal framing (approach success vs. avoid failure), the relation between goals and cognition (which, by implication, entails all of cognitive psychology), goal hierarchies, and macro goal studies with organizations of different sizes. More studies on the relationship between conscious and subconscious goals would also be valuable.

Purpose - This study's purpose is to investigate the impact of supply chain management (SCM) factors among targeted Korean distribution firms. Antecedents are established for supply chain orientation (SCO) for the management and organization of cultural assets. The research sets up SCO corresponding to management cultural assets and to organizational factors in the results. The research model is created to examine the SCO based on a strategic perspective and the operational performance of the SC and SCM. In addition, an integrated model is constructed to analyze the moderating effect by setting partner cooperation as a relational capital factor. The main aim of this study is to analyze the characteristics of the supply chain structure as a source of competitive advantage for distribution service firms participating in the supply chain. In the moderating effects analysis, the role of partner cooperation as relational capital is examined in detail. Research design, data, and methodology - The study examined the existing research related to supply chains, discussing the antecedents of the performance of SCM and SCO. SCM was established with the partner's cooperation as relational capital. Including the moderating effects of the partner cooperation, the research proposed a seven hypotheses path analysis model. The samples were collected from the Korean export enterprises in the distribution service sector, with 185 samples selected for the final analysis. To try and measure the four latent variables presented in the analysis model based on existing studies, 22 measurement items were used. The empirical analysis used the appropriate PLS (partial least squares) method on the path analysis reliability and validity and for common method bias. After testing the seven hypotheses, the research tested the moderating effects to the path analysis. Using PLS as structural equation modeling, the seven hypotheses were tested including the moderating effects of the partner relational capital on the 185 samples. Results - In the results, the SCO had a positive impact on both SCM and the relational capital of partner cooperation. The SCM had a significant impact on the operational performance of the SC. Further, partner cooperation also had a significant impact on SCM and the operational performance of the SC. The moderating effect analysis of the SCM and partner cooperation found a significant impact on the operational performance of the SC. On the other hand, the moderating effect of the SCO and partner cooperation did not affect the SCM. Conclusion - The results of this research show that the existing supply chain-related research can be applied to the operational performance of the SC for a Korean distribution service firm. In view of the fact that SCO is a source of competitive advantage, it should be taken into account when a firm wants to improve the performance of the SCM of the distribution service. This is because it can be assumed that SCO plays a role in supply chain management for the distribution firm.

Purpose - This study aimed to investigate the effect of entrepreneurial temperament (ET) such as innovativeness, risk-taking, and proactiveness in entrepreneur's lifetime before start-up and the effect of social capital (SC) such as network ties and trustworthiness on entrepreneurial intention. Research design, data, and methodology - We examined the components of ET (innovativeness, risk-taking, and proactiveness) and components of SC (network ties and trustworthiness) through existing prior research and investigated the factors that affected entrepreneurial intention. The first hypothesis of this study was that entrepreneurial temperament will have a significant impact on network ties of social capital, and the second hypothesis assumed that entrepreneurial temperament will have a significant effect on the trustworthiness of social capital. Finally, the second hypothesis assumed that social capital will have a significant impact on entrepreneurial intentions. We collected 175 data using questionnaires for people who have not yet started a start-up. And we used the Structure Equation Modeling (SEM) to evaluate the collected data and to test the research model by the two step research procedure. Results - As a result, the innovativeness and proactiveness of ET have a significant effect on network ties and trustworthiness of SC, but the effect of risk-taking on risk-taking of SC is not significant. On the other hand, network ties and network ties of SC was revealed a significant effect on the EI. Conclusions - The implications of this article could be observed as mentioned in this paper. First, we found that entrepreneurial innovativeness and proactiveness are helpful in constructing SCs, but not risk-taking. These results demonstrated that ET of entrepreneurs is important factor in the formation of social capital. Second, the SC that an entrepreneur built before the start-up has a meaning for EI. In conclusion, ET was affected partially to EI mediated SC. It is academic in that ET and SC are independent from each other and have a mediating role between ET and EI, unlike those directly affecting EI. Although some important implications were found in this study, this study had some limitations and we hope that future research will be complemented.

기술정책은 기술획득을 위한 민간투자가 적정수준 이하로 과소투자되는 성향을 보전하는 중요한 정책수단이다. 그러나 기술정책과 관련된 정부정책에 대한 정량적 평가는 아직도 초보적 수준에 머물러 있다. 본 연구는 과제수준에서 기술개발지원제도의 성과를 계량경제학적 모형(Probit)을 이용하여 분석하고 있다. 정부의 지원, 민간부문의 대응 투자(현금과 현물), 기술개발과제 수행형태, 수행주체간의 역할 등이 기술적 성과에 미치는 영향을 가설을 검증하는 형태로 살펴보았다. 총투자규모 보다는 투자의 구성 및 내용이 중요하고, 기업의 대응투자, 특히 현금투자의 정도가 기술적 성과에 크게 영향을 미치며, 기업의 현금투자와 현물투자는 대체재 관계라는 정책적 시사점이 높은 결과들이 도출되었다. 이러한 결과들은 향후 추가적인 연구와 더불어 새로운 국가기술 개발지원제도의 기획은 물론 그 효율성 평가에도 많은 도움과 함께 시사점을 줄 것으로 기대된다.

Many studies to cope with the present problems of Korean coastal and offshore fisheries has been performed, but these were done partly in necessities and general studies for Korean inshore and offshore fisheries are in early stage. Most of these studies adopted analytical way of approach for each fishery individually and they could not reflect the effect of correlated interaction among fisheries on the several common species/stocks, and thus optimal effort allocation was impossible. To consider general fisheries and optimal effort allocation among competing mixed species, a linear programming (LP) approach is applied in this study and introduced into 16 important inshore and offshore fisheries with 13 constraining species which were chosen by annual yield order. This study is not based on the biological interaction among species (i.e., prey - predator system) but the technological interaction between species and fishing efforts. For the application of LP model in these fisheries, the standardization of fishing efforts through different fishing gears could not be successful and a new way of effort standardization through CPUE for vessel tonnage was originated. Total standardized fishing effort on a particular species i, Ei, is computed as the linear summation of standardized fishing effort generated by each fishery j. That is, (equation omitted) where $f_{j}$ is the total vessel tonnage of fishery j and aij is the coefficients contributing to the standardized fishing effort per ton for species i taken in fishery j. The total fishing effort level on species i due to both directed fishing and by - catch can thus be accounted in the aij's. Optimal effort allocation among the j fisheries may be considered a minimizing problem (minimize $\Sigma$ $f_{j}$), subject to the constraints that standardized fishing effort levels on particular species are maintained at, above, and below certain predefined levels. Fishing effort goals for individual species can be based on various biological and/or economic criteria, i.e., fishing effort level generating maximum sustainable yield and/or maximum economic yield. But in this study the $F_{0.1}$ criteria which was accepted as an approximate level for $F_{mey}$ by Outland and Boerema's (1973) study. The findings of this study are, (1) LP model can be applied to the Korean inshore and offshore fisheries giobally. (2) Through a new way of combining multiple different fisheries' efforts for a particular species together generating standardized fishing effort, Schaefer curve could be applied to the complex system successfully. (3) The results of this study for total reduction scale were mostly the same as those of prior studies, but different much from the individual scales of reduction. This study showed the necessities for exploitation of more concrete parameters to put into consideration of profitability of fisheries and social factors, and this model can be modified according to the actual constraints. Also, considering the age structure of stocks, this model can be developed into better one for better fisheries management.ent.

지반의 동결-융해 과정에 의한 지반구조물의 거동 특성을 이해하기 위해서는 지반내 간극수의 상변화와 지반과 구조물의 상호작용에 대한 이해가 필요하다. 본 연구에서는 모듈러 도로시스템의 동결융해의 영향에 대한 수치해석적 연구를 수행하였다. Neumann의 동결-융해 이론식을 이용하여 기본 지반 물성치와 지중과 지표면의 온도조건에 대한 동결심도와 히빙량을 예측할 수 있으나, 지반의 완전포화 및 완전동결의 제한된 경우에만 적용할 수 있다. 동결지수에 따른 모듈러 도로시스템의 수치해석은 다양한 지반조건과 지하수위에 대하여 수행되었다. 동결 히빙량은 화강풍화토이나 모래지반에 비하여 실트질 지반에서 매우 크게 발생하였으며, 지하수위의 저하는 동결 히빙량을 감소시켰다. 실트질 지반에 설치된 도로시스템의 온도이력에 대한 수치해석은 지표면의 동결-융해 과정을 거치면서 지표면에 잔류히빙을 예측하였다. 이는 지반의 강성과 지지력을 급격하게 감소시켜 모듈화 도로시스템의 안정성과 사용성을 저해할 수 있다. 다만, 화강풍화토와 모래지반의 경우는 잔류 히빙량은 미비한 것으로 나타났다. 모듈러 도로시스템은 기존 도로포장 시스템과 달리 지지구조 상부에 설치된 포장 구조물이므로, 포장 구조물의 균등 연직변위와 부등 변형에 대한 엄격한 기준이 적용되어야 할 것으로 사료된다.

해일에 의한 바닷물의 월류는 방조제 구조물에 피해를 유발시킨다. 지금까지 발생된 마운드 형태 방조제의 파괴 유형 조사 결과, 육지 쪽 마루부 파손과 선단부의 세굴이 대표적인 파괴 사례로 지목되었다. 이와 같은 파괴를 유발하는 가장 큰 원인은 월류에 의해 발생된 압력과 유속이다. 본 연구에서는 에너지 관점에서 마운드 형태 방조제에서 압력과 유속을 산정할 수 있는 이론해를 제안하고 검증하였다. 이를 위해 방조제 마루부와 선단부에 흐름을 유사정적비회전류로 보고 동심원유선이 형성된다고 가정하였다. 한계흐름조건과 베르누이정리를 이용하여 방조제 마루부와 배면 선단부에서의 작용하는 압력 및 유속 산정식을 유도하였다. 이들 식을 이용하여 동심원유선 및 월류고를 가정하여 마루부와 선단부에서 압력과 유속을 산정하였다. 그 결과 마루부에서는 부의 압력이 선단부에서는 양의 압력이 각각 크게 작용하는 것으로 나타났으며 유속에 의한 전단응력도 작용하는 것을 확인하였다. 또한 제안된 이론해의 적용 한계에 대한 고찰도 이루어졌다.

본 연구는 신종플루 관련 뉴스 이용 정도가 개인 및 공중에 대한 건강보호 행위의도에 미치는 영향을 보호동기이론(protection motivation theory)을 통해 살펴보았다. 구체적으로 신종플루 뉴스 이용 정도를 독립변인으로, 심리적 보호동기요인(신종플루에 대한 인지된 심각성, 취약성, 대처효능감, 자기효능감)을 매개변인으로 그리고 개인과 공중에 대한 건강보호 행위의도를 종속변인으로 설정하였다. 대학생 460명을 대상으로 설문조사를 실시하여 각 구성요인 간의 인과관계를 연구모형으로 설정하고 구조방정식모델(SEM)로 분석하였다. 연구결과에 의하면, 첫째 '개인 건강보호 행위의도' 연구모형에서 신종플루 뉴스 이용 정도는 신종플루 관련 보호동기 요인들에 유의미한 인과관계를 나타냈으나 '대처효능감'은 제외되었다. 또한 세 가지 보호동기 요인(지각된 심각성, 지각된 취약성, 자기효능감)들은 개인 건강보호 행위의도에 유의미한 정적 인과관계를 나타냈다. 둘째 '공중 건강보호 행위의도' 연구모형에서 신종플루 뉴스 이용 정도는 '대처효능감'을 제외한 모든 보호동기 요인에 유의미한 관계를 나타냈으며 보호동기 요인들 중에 '인지된 취약성'과 '대처효능감'만이 공중 건강보호 행위의도에 유의미한 정적 인과관계를 나타냈다. 두 연구모형의 공통점으로는 신종플루 뉴스이용 정도가 개인 또는 공중 건강보호 행위의도에 직접적인 영향을 미치지 않은 것으로 나타났다. 특정 질병에 대한 건강보호 행위의도에 있어서 건강보호 대상(자신 혹은 타인)이 누구인가에 따라 심리적 보호동기들은 다르게 작동하는 것으로 추정된다.
