건설산업에서 자재와 관련된 비용은 프로젝트 특성에 따라 다르지만 일반적으로 원가구성비 측면에서 40% 이상을 차지한다. 최근 대형화, 전문화, 복잡화 되어가는 건축 공사에서 자재의 반입, 이동 및 적재공간의 협소로 인해 자재관리가 매우 복잡하다. 하지만 대부분의 경우 자재관리는 현장 관리자의 경험에 의존해 관리되고 있으며 건설관리분야 중 자재관리의 중요성에 대한 인식도 낮은 실정이다. 이에 대한 건설 산업에서 자재관리에 대한 연구도 활발히 진행되고 있다. 본 연구에서는 자재의 속성에 따른 MTS(Make-to-stock), ATO(Assemble-to-order), MTO(Make-to-order), ETO(Engineered-to-order)의 네 가지 분류 방법과 자재 조달 특성 및 자재 고유 특성 분석을 통하여 현장 자재의 효율적인 공급관리를 위한 자재의 속성별 관리체계를 분석한다. 이를 이용하여 자재 속성별 자재관리 프로세스를 제안한다.

Purpose - Most studies related to emotional labor have been conducted in the low-contact service industry rather than the high-contact service industry. Since the subjects of this study were golf service assistants, working in an industry in which the interaction and contact between customers and employees are considerable and the degree of customization is high, this study is significant. Thus, we would like to focus on the relationship between the humor style of golf service assistants and emotional labor. Humor style was divided into two styles-adaptive humor and maladaptive humor. Emotional labor was divided into two dimensions-surface acting and deep acting. In addition, we identify the relationship between emotional labor, job satisfaction, and turnover intention. Research design, data, & methodology - This study focuses on the humor styles in the golf service industry, among golf service assistants, on their emotion labor, and verifies the relationship between emotion labor and work satisfaction or job turnover intention. Based on the outcome, a total of four hypotheses were set up. To verify the hypotheses, surveys were conducted on the golf service assistants working in two golf fields in the region of Busan as well as its neighboring area. A total of 250 copies of the questionnaire were distributed. Subsequently, a total of 227 valid questionnaire copies, after excluding improper responses, were used in the analysis. After verifying the reliability and feasibility of variances, Amos 18.0 was used to implement the structure method so as to verify the study hypotheses. As a result of this analysis, the suitability of the entire model was considerably appropriate to the standard value, and the level is adequate to accommodate the study model completely. Results - First, it was found that the adaptive humor of golf service assistants had a positive effect on deep acting and maladaptive humor had a positive effect on surface acting. Second, It was found that employees' satisfaction with their job was reduced through surface acting, and those employees who experienced positive emotional labor in the form of deep acting were more satisfied with their job. Third, surface acting among employees increased turnover intention, but deep acting reduced it. Finally, the relationship between job satisfaction and the turnover intention of golf service assistants in the golf service industry was examined. Conclusions - First, the adaptive humor of the golf assistants in the golf service industry had a positive effect on their expression behavior. Second, deep acting increased their job satisfaction while their surface acting had a noticeably negative effect on their job satisfaction. Third, the surface acting of the emotion labor dimensions that the golf service assistants experience increases their turnover intention while their deep acting decreases their turnover intention. Finally, when analyzing the relationship between job satisfaction and turnover intention of the golf service assistants, it was found that the turnover intention decreased when their job satisfaction is increased.

Objectives: Poisonous substances experts engage in policymaking regarding poisonous substances, whereas poisonous substances managers perform legal duties related to poisonous substances management systems at worksites. To understand and improve poisonous substances designation systems, it is necessary to distinguish the roles of these experts and managers. We further aimed to identify problems with poisonous substances appointment systems and provide basic data for their improvement by investigating the knowledge and recognition of the need for system improvement among managers and experts. Methods: To determine the $subjects^{\circ}{\emptyset}$ awareness of poisonous substances designation systems, a selfadministered questionnaire comprised of items on general characteristics and knowledge and recognition of the need for system improvement was issued. Data were analyzed via t-tests and ANOVA using SPSS v 16.0 Results: Regarding system comprehension, managers (n=213; mean 3.28, SD 0.63) significantly differed from experts (n=35; mean 4.08, SD 0.59) (P<0.001). No differences were found in recognition of need for improvement between managers (mean 3.11, SD 0.34) and experts (mean 3.24, SD 0.31). Significant differences in comprehension were found among managers by education level (P<0.05) and company size (P<0.05). Regarding industry type, comprehension was greater in the electrical/electronic and chemical/environmental industries compared to in other industries (P = 0.066). Comprehension was higher among those with five years or more of experience compared to those with less than five years. Regarding recognition of need for improvement, managers showed significant differences by company size (P<0.05). $Experts^{\circ}{\emptyset}$ comprehension showed no differences by general characteristics, while need for improvement differed according to work experience (P<0.001). Conclusion: The study found that the bigger the company size, the higher the level of comprehension by managers and the experts. In the case of both groups, where a higher comprehension of the poisonous substances designation system was evident, they recognized the necessity of its improvement.

Objective: This paper presents additional considerations related to organization and safety culture extracted from recent human error incidents in Korea, such as station blackout(i.e., SBO) in Kori#1. Background: Safety culture has been already highlighted as a major cause of human errors after 1986 Chernobyl accident. After Fukushima accident in Japan, the public acceptance for nuclear energy has taken its toll. Organizational characteristics and culture became elucidated as a major contributor again. Therefore many nuclear countries are re-evaluating their safety culture, and discussing any preparedness and its improvement. On top of that, there was an SBO in 2012 in the Kori#1. Korean public feels frustrated due to the similar human errors causing to a catastrophe like Fukushima accident. Method: This paper reassesses Japan's incidents, and revisits Korea's recent incidents. It focuses on the analysis of the hazards rather than the causes of human errors, the derivation of countermeasures, and their implementation. The preceding incidents and conclusions from Japanese experience are also re-analyzed. The Fukushima accident was an SBO due to the natural disaster such as earthquakes and a successive tsunami. Unlike the Fukushima accident, the Kori#1 incident itself was simple and restored without any loss and radioactive release. However, the fact that the incident was deliberately concealed led to massive distrust. Moreover, the continued violation of rules and organized concealment of the accident are serious signs of a new distorted type of human errors, blatantly revealing the cultural and fundamental weakness of the current organization. Result: We should learn from Japanese experiences who had taken pride in its safety technology and fairly high confidence in safety culture. Japan's first criticality accident in JCO facility splashed cold water on that confidence. It has turned out to be a typical case revealing the problems in the organization and safety culture. Since Japan has failed to gain lessons and countermeasure, the issue persists to the Fukushima incident. Conclusion: Safety culture is not a specific independent element, which makes it difficult to either evaluate it properly or establish countermeasures from the lessons. It may continue to expose similar human errors such as concealment of incident and manipulation of bad data. Application: Not only will this work establish the course of research for organization and safety culture, but this work will also contribute to the revitalization of Korea's nuclear industry from the disappointment after the export contract to UAE.

In the era of 20 nm scaled semiconductor volume manufacturing, Microelectronics Manufacturing Engineering Education is presented in this paper. The purpose of microelectronic engineering education is to educate engineers to work in the semiconductor industry; it is therefore should be considered even before than technology development. Three Microelectronics Manufacturing Engineering related courses are introduced, and how undergraduate students acquired hands-on experience on Microelectronics fabrication and manufacturing. Conventionally employed wire bonding was recognized as not only an additional parasitic source in high-frequency mobile applications due to the increased inductance caused from the wiring loop, but also a huddle for minimizing IC packaging footprint. To alleviate the concerns, chip bumping technologies such as flip chip bumping and pillar bumping have been suggested as promising chip assembly methods to provide high-density interconnects and lower signal propagation delay [1,2]. Aluminum as metal interconnecting material over the decades in integrated circuits (ICs) manufacturing has been rapidly replaced with copper in majority IC products. A single copper metal layer with various test patterns of lines and vias and $400{\mu}m$ by $400{\mu}m$ interconnected pads are formed. Mask M1 allows metal interconnection patterns on 4" wafers with AZ1512 positive tone photoresist, and Cu/TiN/Ti layers are wet etched in two steps. We employed WPR, a thick patternable negative photoresist, manufactured by JSR Corp., which is specifically developed as dielectric material for multi- chip packaging (MCP) and package-on-package (PoP). Spin-coating at 1,000 rpm, i-line UV exposure, and 1 hour curing at $110^{\circ}C$ allows about $25{\mu}m$ thick passivation layer before performing wafer level soldering. Conventional Si3N4 passivation between Cu and WPR layer using plasma CVD can be an optional. To practice the board level flip chip assembly, individual students draw their own fan-outs of 40 rectangle pads using Eagle CAD, a free PCB artwork EDA. Individuals then transfer the test circuitry on a blank CCFL board followed by Cu etching and solder mask processes. Negative dry film resist (DFR), Accimage$^{(R)}$, manufactured by Kolon Industries, Inc., was used for solder resist for ball grid array (BGA). We demonstrated how Microelectronics Manufacturing Engineering education has been performed by presenting brief intermediate by-product from undergraduate and graduate students. Microelectronics Manufacturing Engineering, once again, is to educating engineers to actively work in the area of semiconductor manufacturing. Through one semester senior level hands-on laboratory course, participating students will have clearer understanding on microelectronics manufacturing and realized the importance of manufacturing yield in practice.
