This study is the empirical analysis of the effects of GWP organization culture on need for achievement, job satisfaction, and job performance. For this analysis, among the major companies that have been selected as good corporates to work (GWP), the survey was conducted by targeting the employees in manufacturing/service/finance industries and the comparison analysis is on the relationship between the effects and variables of the GWP organization culture are effected the professionals in the industries. As for the results of the studies, firstly, in manufacturing industry, GWP organization culture has significant impacts on need for achievement(+) and job satisfaction(+) and does not have significant effects on job performance. Also, need for achievement has significant effects on job satisfaction(+) and job performance(+) and job satisfaction has significant effects on job performance(+). Secondly, GWP organization culture in service industry has significant effects on need for achievement(+) and job satisfaction(+) but does not have significant effects on job performance. Need for achievement has significant effects on job satisfaction(+) but does not have significant effects on job performance and job satisfaction does not have significant effects on job performance. Lastly, GWP organization culture in finance industry has significant effects on need for achievement(+), job satisfaction(+), and job performance(-) and need for achievement has significant effects on job satisfaction(+) and job performance(+) and job satisfaction has significant effects on job performance(+). Based on the results of the analysis, this study suggests the meanings and implications on the similarities and differences on how GWP organization culture affects employees in different industries.

Currently, semiconductor manufacturing industry heavily relies on a wide range of high global warming potential (GWP) gases, particularly during etching and cleaning processes, and their use and relevant carbon emissions are subject to global rules and regulations for achieving carbon neutrality by 2050. To replace high GWP gases in near future, dry etching using alternative low GWP gases is thus being under intense investigations. In this review, we report a current status and recent progress of the relevant research activities on dry etching processes using a low GWP gas. First, we review the concept of GWP itself and then introduce the difference between high and low GWP gases. Although most of the studies have concentrated on potentially replaceable additive gases such as C₄F₈, an ultimate solution with a lower GWP for main etching gases including CF₄ should be developed; therefore, we provide our own perspective in this regard. Finally, we summarize the advanced dry etch process research with low GWP gases and list up several issues to be considered in future research.

The government announced a number of policy on service industries and pushing. over the past 10 years. Important role in the service industry is a very large degree job creation, as well as employment impacts have had a stable employment skills. In June 2015 the Bureau of Statistics released the youth unemployment rate (15~29 years) showed a 10.2%. The service industry is recognized as one of the alternatives that can overcome the deteriorating economic situation this way. Is there a difference between industry by type what performance management is applied when this service was variable with a GWP of Korean? Can GWP variables are variables which are more important to recognize the service industry? GWP variables having a certain impact on the activities of the member teamwork, job involvement has what effect on? And the impact on business performance relationship who only proven case studies whilst also want to empirical verification.

본 연구는 스타트업을 포함 중소벤처기업에 재직 중인 구성원의 직무만족과 소명의식을 높이기 위한 방안으로 GWP 조직문화의 필요성을 제안하고자 한다. GWP 조직문화는 구성원들이 자신이 근무하는 조직과 업무, 동료에 대해 애착을 갖고 자부심을 갖도록 조직 차원에서 이를 독려하는 문화적 풍토를 말한다. 이를 토대로 구성원은 일터영성(Workplace Spirituality)을 지각하고 더 나아가 직무만족과 소명의식을 느낄 수 있다. 일터영성에 관한 개념은 다양한 학문적 논의가 진행되고 있는데 중요한 점은 구성원들이 자신의 업무에서 의미를 추구하는 소명의식과 일터, 즉 조직에서 목적과 일의 의미를 타 구성원과 함께 공유하는 개념으로 요약할 수 있다. 그러므로 중소벤처기업에서 GWP 조직문화 조성을 노력한다면 구성원에게 자신의 업무와 동료에 대한 인식 그리고 일터 현장에 대한 의미와 소중함을 더욱 인식하게 하여 임직원의 일터영성을 일깨울 수 있을 것이다.

Looking at the cargo trend of Gwangyang port (GWP) during past decade, petrochemical items grew by 26% and steel item grew by 12%, but container cargo just grew by 4%. Thus, Yeosu-Gwangyang Port Authority (YGPA) sets the port development initiative targeting at industrial core port considering GWP's strength as multi function port and industrial port and GWP's weakness as lower container cargo growth trend. The purpose of this study is proposing the projects about the GWP's industrial core port development. The results of the study is as follows. As a prerequisite for development as an industrial core port, it was suggested to form a consensus on the modification or change of the port performance index of univariate port cargo volume. The following three tasks were presented for GWP to develop as an industrial core port. It can be said that it is most necessary to derive, manage, and monitor GWP industrial core performance indicators. Next, it is necessary to conduct a survey on the satisfaction of industrial support in ports. Finally, it is necessary to measure the added value of the port area of GWP hinterland.

In this study, the seawater Heat Pump System using seawater with temperature of annual domestic conditions ($0^{\circ}C$ to $25^{\circ}C$) is designed in order to compare its performance against the Heat Pump using unused heat of seawater. As a potential replacement for current refrigerants that exacerbate global warming and ozone delpetion, a Low GWP refrigerant's performance is analyzed. The basic water to water Heat Pump system is chosen and three commercial refrigerants - R134a, R410a, R32 - are used to compare against new Low GWP refrigerant R1234ze. When seawater with temperature of $25^{\circ}C$ is used, the performance change showed maximal increase in COP, 38.3%. low GWP refrigerant R1234ze, showed great performance characteristics reach to 5.242 and Existing commercial refrigerant, R134a showed only less than 0.03 performance difference against R1234ze. The study confirms notable performance of R1234ze refrigerant through simulation as environmentally friendly refrigerant for domestic seawater Heat Pump.

This study aims at evaluating environmental impacts on recycling process of used small household appliances. The recycling process mainly consists of manual dismantling, crushing and various sorting processes to effectively recover valuable resources and to minimize environmental impact. In this study, life-cycle assessment (LCA) methodology is applied to analyze major environmental parameters such as GWP, ADP, POCP, EP, etc. One of the major impact categories on the weight basis in the recycling process is global warming (GWP) 57.1%, next to ADP 35.4% and POCP 4.8%, respectively. As a result of environmental impact on recovery of valuable resources/ton, the GWP of plastics for ABS is highest (33.7%) compared to ferrous metals (9.4%). The effects of environmental and economical benefit are also analyzed to compare with the amount of virgin materials to be recycled by recycled materials. In addition, recycled materials are also more economical in comparison to virgin materials due to the environmental avoiding effect by recycling. In conclusion, the key environmental issues related to the recycling of e-wastes are analyzed and therefore, the effective recycling process will contribute to mitigate global warming potential in the near future.
