The purpose of this study is to identify the priorities with respect to the characteristics of tourism resources development plan between the South and the North Korea. Through a preliminary investigation 287 lists of questions were distributed from May 14, 2012 to December 5, 2012 and from among them 252 lists were used. Expert Choice 11.5 was used to do pairwise comparisons and priorities assessment. Based upon the results of empirical analysis, the priority order sets of the domain of tourism resources development plan should be related to the development contents, the development objects, the development patterns, and the development subjects in the South Korea. Those should be related to the development subjects, the development objects, the development contents, and the development patterns in the North Korea.

The purpose of this study is to examine the eco-systemic factors that affect the independent will of female single parent householder The subjects were 176 female single parent householder who reside in public facilities for single mother family. Collected date were analyzed through frequency, percentage, correlation and hierarchical regression analysis. The results are as follow. The factors that affect the female single parent householder's independent will are the age, duration of living in public facilities, levels of self-efficacy, the ability to cope with problem-solving, and the levels of support received from extended family. According to these findings, intervention strategies that focus on increasing the female single parent householder's independent will are suggested.

Recently, BIM has attracted attention as a technology to improve the construction productivity. The BIM standards to be applied to the BIM project are necessary for using or connecting the current 2D-based drawing standards. To develop the standard for BIM-based QTO and cost, this paper focused on using QDBEx, which was applied to road project cost management and connecting QDBEx with IFC, which is the BIM data delivery format. The IFC schema was evaluated to determine if it is possible to use the converts to the QDBEx XML file. As a result, 66% of the whole was available to connect directly, and 17% was available to connect through the processing of instance. The remaining 17% was evaluated to determine if it was available to connect. In the future, improvements in the schema will be suggested based on these results.

In this paper, we proposed the method called "DoublePico"(Double Piconet) forovercoming low data transmission rate in a scatternet. This needs a new Ad-hoc network topology to transmit with high rate. Every node performs the function of the relay station. DoublePico has two bluetooth devices that should form two different poconets; every node can make a link between two different piconets. Two different piconets are linked in one node by the link with two bluetooth divices thereby forming the Ad-Hoc network. In this paper, we shows the method of DoublePico which supports about 457kbps of the maximum data transmission rate. This method supports a higher data transmission rate than the traditional bluetooth's Ad-Hoc topology by using analysis and comparison of existing algorithm of bluetooth specification and simulation results. Specifically, this paper focuses on the impact of intererence on the PER (Packet Error Rate), throughput performance, and the throughput improvement with SAW(Stop and Wait)-ARQ scheme in DoublePico.

The purpose of the study was to understand how the interplay between organizational and national cultures affects the management of IUICs (International University-Industry Collaboration) devoted to technology innovation and transfer. This study presents two examples of IUIC drawn from a qualitative research method, both involving a British university and a Japanese company. The first case illustrates how different organizational practices (organizational culture), which are nested in the national culture (values), raise questions about the role of ethical boundaries in causing misunderstandings and the deterioration of UIC relationships. The second case demonstrates how long-term relationships and extensive interpersonal interactions can play a positive role in IUIC. Practical implications, the limitation of this study and further studies have been discussed.

Multiple response surface optimization (MRSO) aims at finding a setting of input variables which simultaneously optimizes multiple responses. The minimization of mean squared error (MSE), which consists of the squared bias and variance terms, is an effective way to consider the location and dispersion effects of the responses in MRSO. This approach basically assumes that both the terms have an equal weight. However, they need to be weighted differently depending on a problem situation, for example, in case that they are not of the same importance. This paper proposes to use the weighted MSE (WMSE) criterion instead of the MSE criterion in MRSO to consider an unequal weight situation.

본 연구는 조직의 작업정보환경이 개인의 피이드백 추구 행위에 어떤 영향을 주는가에 관한 탐색적인 연구이다. 피이드백 추구 행위를 '탐지'와 '문의'의 유형으로 나누되, 피이드백 원천에 따라 상사에 대한 문의, 상사에 대한 탐지, 동료에 대한 문의, 동료에 대한 탐지를 구분하였으며, 작업정보환경은 피이드백 원천(상사, 동료, 자기자신)으로부터의 피이드백을 피이드백 부호(긍정적 피이드백, 부정적 피이드백)에 따라 평가하였다. 연구의 방법은 군 헬리콥터 조정사 훈련생 187명을 대상으로 질문지 방법에 의하였다. 연구의 결과 첫째, '탐지'와 '문의'의 피이드백 추구행위는 정의 상관관계를 보임으로써 피이드백 추구전략으로서 두 행위 유형은 서로 대체관계에 있지 않으며, 특정 유형의 피이드백 추구행위가 오히려 다른 유형의 피이드백 추구행위에 대한 필요성을 높여주고 있는 것으로 나타났다. 즉, '탐지'를 통한 피이드백과 '문의'를 통한 피이드백은 적어도 질적으로 상이한 정보를 제공하여 주는 것으로 인식되고 있음을 알 수 있다. 둘째, 어떤 원천으로부터 제공되었거나 추구된 피이드백 정보는 다른 피이드백 원천으로의 추구행위와 정의 상관관계를 보임으로써, 여러 피이드백 원천들로부터 제공되는 피이드백 정보는 피이드백 수신자에게 서로 대체적인 역할을 하지 않으며, 특정 피이드백 원천으로부터의 피이드백은 피이드백 수신자로 하여금 질적으로 상이한 정보를 제공하여 주는 것으로 인식되는 상이한 원천으로부터의 피이드백을 추구하도록 한다는 것을 알 수 있다. 셋째, 작업정보환경에서 긍정적 피이드백이 주어지면 인상관리의 측면에서 적극적으로 피이드백을 추구하는 경향이 있었으며, 부정적 피이드백이 주어진 경우, 본 연구에서와 같이 성과가 매우 중요시 여겨지는 조직에서는 개인이 그 정보적 가치를 높게 평가하여 대체로 피이드백을 적극적으로 추구하는 경향이 있는 것으로 나타났다.

The permeability of cathodic electrolyzed water toward electrophoretic gel and dissolvability of cathodic electrolyzed water toward green tea components were compared with those of general waters in this investigation. Stained band intensities of the proteins by CBB-R prepared in cathodic electrolyzed water were compared with those in deionized water for various time intervals. Proteins were stained first by CBB-R in cathodic electrolyzed water as compared with those by CBB-R in deionized water. Moreover, cathodic electrolyzed water showed dramatically enhanced solubility toward green tea components at $25^{\circ}C$ than general waters. These results suggest much greater permeability and dissolvability of cathodic electrolyzed water than those of general waters.

In this paper, durability test of 1000cc level gasoline engine has been carried out. Durability test set total 300 hours and WOT condition. Engine torque, power, fuel consumption, blow-by gas flow rate, and oil pressure are measured to analyse performance variation by time. As a result, engine performance of high rpm range gradually reduced by time but for relatively low rpm range shows stable performance. Blow-by gas flow rate shows 0.4% of averaged induction air flow rate, which is excellent rate for 1000cc level gasoline engine. Engine torque and fuel consumption data show the break-in upto 100 hours and aging trend after that. After 300 hours, engine is disassembled and each part is checked for the damage or crack.

현재 Bacillus cereus의 정량 및 정성 분석을 위해서 MYP 배지가 주로 사용되고 있으나 식품공전과 축산물의 가공기준 및 성분 규격 내에서 MYP의 주요 첨가물인 egg-yolk의 농도는 각각 2.5%와 5%로 서로 상이하여 대상이 되는 시료의 유래에 따라 각기 다른 MYP 배지를 제조해야 하는 불편함이 있다. 따라서 본 연구는 MYP 배지에 1%에서 10%로 10개 구간으로 egg-yolk의 농도를 첨가하여 이에 따른 B.cereus의 정량적 특성, lecithinase 활성대의 크기 및 육안 확인이 가장 좋은 구간대에 대한 관능평가를 실시하였다. 결과적으로 정량적 특성과 lecithinase 활성대의 크기는 농도가 증가할수록 비례하지 않음을 알 수 있었으며, lecithinase 활성대에 대한 관능평가는 2%의 egg yolk가 가장 확인이 용이한 것으로 평가되었다. 본 연구를 통해서 MYP에 첨가되는 egg-yolk의 최종 농도가 현재의 2.5%(식품), 5%(축산물)로 다르게 기준 되어 있는 것을 2% 또는 식품공전의 2.5%로 통합하여 개정하는 것이 가능하다고 판단되며 이러한 개정을 통하면 MYP 조성물 중 고가인 egg-yolk 제조 비용을 상당히 줄여 줄 것으로 기대된다.
