Natural convection flows in a cubical air-filled cavity that has one pair of opposing faces isothermal at different temperatures, $T_h\;and\;T_c$ respectively, the remaining four faces having a linear variation from $T_c\;to\;T_h$ are numerically simulated by a solution code(PowerCFD) using unstructured cell-centered method. An extension to a previously published work, special attention of this work is paid to three-dimensional flow and thermal characteristics in nature convection according to new orientation at Ra= $1{\times}105$. Comparisons of the average Nusselt number at the cold face are made with benchmark solutions and experimental results found in the literature. It is demonstrated that the average Nusselt number on the cold face has a maximum value around the diamond-type inclination angle of $43.2^{\circ}\;at\;Ra=1{\times}105$. We also report the effect of new orientation on the type of flow and temperature structure in a cubical-cavity.

It should be unthinkable to not provide water at survival of any living things. Water is too a basic element for development for a country. Currently, the global market of mineral water is growing rapidly. This study, I conceptualized mineral water as bottled water. In particularly, bottled water has seen huge global growth for the last few years. The annual growth rate of the market in the period 2005-2009 was 5.9%. Following a surge in obesity and subsequent health and wellness trends, many consumers are switching from sugary soft drinks to healthier alternatives. Therefore, the global bottled water market is one area which has big potential for growth, but price competition is getting intensified among multi-national and domestic firms. Korean providers too are faced with strong competition in growing domestic market. The bottled water market has presence of multinational provider like Nestle, Danone and Coca-Cola, which collectively account for 35.1% of the world market share in 2009. On the basis of a market orientation approach, this article looks at changing environments in the world mineral water industry and attempts to describe foreign market entry strategy of the Korean mineral water industry. The market orientation provides strong norms for learning from customers and competitors, is instrumental in creating a superior value for buyers, innovating successfully, and generating excellent firm performance. So firms should consider a strategic planning in basis on market orientation before they enter foreign markets. Some discussions were made about managerial implications for Korean bottled water providers.

The copper deposit on steel plate was prepared by pyrophosphate copper plating solution made with variation of inorganic additive. $NH_4OH$ and $NH_4NO_3$ were used as inorganic additives. The copper layer characteristics - tensile strength, crystallite size and crystal orientation - were evaluated by X-ray diffraction and Universal Test Machine. The presence of ammonium nitrate results in reduction of average roughness value from $0.08{\mu}m$ to $0.03{\mu}m$. In pyrophosphate copper plating solution without Inorganic additive, tensile strength of electrodeposit copper foil was reduced from 600 MPa to 180 MPa after 7 days aging. However, when adding ammonium nitrate, there was almost no change of tensile strength, intensity of crystal orientation - (111), (200) and (220) - and crystallite size (2~30 nm).

A novel method for evaluating the anisotropy of the deterministic features in a stochastic 2D data is introduced. The ability of the wavelet transform for the identification of the abrupt discontinuities could be used to characterize the boundary of the deterministic area in a 2D stochastic data, such as flocs in paper structure. The one-dimensional wavelet transform with a small-scale range in MD and CD could quantify the amount of the edge in both directions, depending on the intensity of each floc. The flocs that are aligned in the MD direction result in a higher value of local wavelet energy in the CD direction. Therefore, the ratio of the total wavelet energy in CD and MD directions can be used as a new anisotropy index. This index is a measure of the floc-orientation and can provide an excellent tool to obtain the orientation distribution and the major oriented angle of flocs. Various simulated images and real stochastic data such as local gloss variation of printed image and formation image, have been tested and the results show this analysis method is very reliable to measure the anisotropy of the deterministic features.

The vehicle attitude and sideslip is critical information to control the vehicle to prevent from unintended motion. Many of estimation strategy use bicycle model or IMU integration, but both of them have limits on application. The main purpose of this paper is development of vehicle orientation estimator which is robust to various vehicle state and road shape. The suggested estimator use 3-axis magnetometer, yaw rate sensor and lateral acceleration sensor to estimate three Euler angles of vehicle. The estimator is composed of two individual observers: First, comparing the known magnetic field and gravity with measured value, the TRIAD algorithm calculates optimal rotational matrix when vehicle is in static or quasi-static condition. Next, merging 3-axis magnetometer with inertial sensors, the extended Kalman filter is used to estimate vehicle orientation under dynamic condition. A validation through simulation tools, Carsim and Simulink, is performed and the results show the feasibility of the suggested estimation method.

Natural convection flows in a doubly-inclined cubical air-filled cavity are numerically simulated by a solution code(PowerCFD) using unstructured cell-centered method. For a physical realizability, the cavity has one pair of opposing isothermal faces at different temperatures, $T_h\;and\;T_c$, respectively, the remaining four faces having a linear variation from $T_c\;to\;T_h$. The paper redefines a new doubly-inclined orientation for the cubical-cavity benchmark problem. Special attention is paid to three-dimensional thermal characteristics in natural convection according to the new orientation at $Ra=4\times10^4$. Comparisons of the average Nusselt number at the cold face are made with benchmark solutions and experimental results found in the literature. It is found that the average Nusselt number at the cold face has a maximum value at the doubly-inclined angle ranging from $40^{\circ}\;to\; 45^{\circ}$ We also report the effect of new orientation on the type of temperature structure in a doubly-inclined cubical-cavity.

The Purpose of the current study is to investigate the differences in cosmetics attribute evaluation, purchase motivation, and brand re-purchase intention with respect to shopping orientations of Korean female university students. Questionnaires were distributed to 250 female students at Kyungpook National University and 220 completed questionnaires were analyzed. The results were as follows. First, shopping orientations and cosmetics attribute evaluation each generated four factor solutions, whereas cosmetics purchase motivations produced three factors. Second, three consumer groups - Efficiency Shopper Group, Indifference Shopper Group Ambivalence Shopper Group - with different shopping orientations were identified. Third, the study found significant differences in consumers' attribute evaluation such as function and price among the groups. The study also revealed a significant difference in contingent purchase motivations and brand re-purchase intention among the groups. From these results, we could identify that cosmetics re-purchase intention was significantly different among three different groups with different shopping orientations. Furthermore, consumer classification according to shopping orientations in cosmetics product purchase can be used by cosmetics marketers and managers to establish product plan and marketing strategy development. Additionally, the current study has originality and value that the relationship between shopping orientation and re-purchase intention has not been studied very much in the cosmetics product domain.

Purpose -The purpose of this paper is to advance the understanding of affective commitment in employees of Korean companies' subsidiaries in Mexico. Specifically, we study the moderating effects of cultural orientation on the relationship between perceived corporate social responsibility (CSR) and affective commitment among these Mexican employees. Research design and methodology - This study was designed to explore the impact of perceived CSR on affective commitment and the moderating roles of collectivism and power distance on the employer-employee relationship. We applied hierarchical regression to survey data collected from 296 employees working for Korean company subsidiaries in Mexico to examine the proposed hypotheses. Results - The results show a significant positive effect from perceived CSR on affective commitment. In addition, this study confirms a positive moderating effect from collectivism and a negative moderating impact from power distance on the relationship between perceived CSR and affective commitment. Conclusions - Drawing upon social identity theory, this study found that Mexican employees' perceptions of their company's CSR and their own cultural value orientations influence affective commitment to the organization. This study extends the understanding of perceived CSR and affective commitment, and particularly demonstrates that the relationship between perceived CSR and affective commitment is influenced by employee collectivistic and power distance orientation.

본 연구는 기업 근무자를 대상으로 정보지향성과 기술사업화능력이 기술성과에 미치는 영향에 관하여 분석하였다. 정보지향성은 정보기술능력, 정보관리능력, 정보행위 및 가치를 기술사업화능력은 제품화능력, 생산화능력, 마케팅능력을 하위변수로 구성하였고 기술축적역량을 조절변수로 하였다. 기업 직장인으로부터 수집한 온라인과 오프라인 설문지 349부에 대한 실증분석을 실시하였다. SPSS v22.0과 Process macro v3.4를 사용한 분석결과 첫째, 정보지향성과 기술성과는 유의적인 영향을 미치는 것으로 나타났고, 정보지향성이 기술사업화능력에 미치는 영향에서는 모두 유의적으로 나타났고, 기술사업화능력의 변수에서 제품화능력과 생산화능력에 미치는 영향력의 크기는 정보기술능력, 정보관리능력, 정보행위 및 가치의 순으로 나타났으나, 마케팅역량에 미치는 영향에서는 앞선 결과와 다르게 정보행위 및 가치, 정보관리능력, 정보기술능력의 순으로 나타났다. 둘째, 기술사업화능력이 기술성과에 미치는 영향에서 정보지향성과 독립적으로 기술사업화능력의 제품화능력, 생산화능력, 마케팅능력은 기술성과에 유의한 영향을 미치는 것으로 나타났다. 셋째, 정보기술능력과 정보관리능력은 기술성과에 유의적인 영향을 미치는 것으로 나타났으나, 정보행위 및 가치에서 제품화능력과 마케팅능력을 경유하는 간접효과는 유의적으로 나타났으나, 생산화능력을 경유하는 간접효과는 비유의적으로 나타났다. 넷째, 기술사업화능력의 하위변수 중 생산화능력과 기술축적 역량의 상호작용항만이 유의적으로 나타났고, 기술축적역량과 제품화능력, 마케팅능력은 비유의적으로 나타났다. 그러므로 생산화능력과 기술성과 간의 관계가 기술축적능력이 높은 기업이 낮은 기업보다 낮을 것이라고 해석할 수 있으며 후속 연구로는 다른 독립변수의 도입, 매개변수 및 조절변수가 도입된 모형을 통한 연구가 필요할 것으로 보인다.
