Supplier Relationship Management (SRM) is a strategic partnership activity for an enterprise and is expected to be a significant performance element in the current enterprise environment where uncertainty is growing. Despite the effective SRM allows companies to manage quality and inventory throughout their logistics procurement process with their suppliers and increase the profitability of the company, there is a scarce of theory about supplier relationship management (SRM) and many companies are not aware of the importance of SRM and depend only on simple electronic purchasing methods. Therefore, I analyze the H Company as a case company, which is a large domestic company and has reached 2,500 domestic and overseas suppliers. SRM process and its effects are evaluated as (1) Purchasing strategy division 2) Process division (3) IT infrastructure division. By analyzing SRM as one of the management strategies that bring the overall value of enterprise performance up, and by looking at how domestic large corporations manage their suppliers, I hope that manufacturers with many suppliers will recognize the importance of SRM and build an SRM tailored to their business.

As of 2018, total yield of lettuce and strawberry amounted to 93,543 tons (representing 1.0 percent) and 183,639 tons (2.0 percent), respectively, among total yields worth 9,185,889 tons in South Korea. Lettuce is affected by a combination of numerous elements such as varieties, cultivation methods and pests during each growth phase (Lee et al., 1999). It is mainly cultivated in spring and fall. Especially due to respiration rate after harvest leading to reduced quality and poor storage, maintaining annual supply is unavailable (Jang et al., 2018). With the distribution of new varieties, forcing culture and indoor insulated facilities for plant cultivation during winter, strawberries are produced every year except for late summer and early fall. Due to active respiration, transpiration, soft flesh and high water content, the fruit is vulnerable to go bad and got rotten compared to other fruits. Furthermore, it is difficult to maintain freshness due to the possibility of softening, discoloration and fungi (Lee et al., 2012). In this regard, developing improved storage and package techniques is needed to ensure maintaining quality and safety even just two to three days after harvest. In order to ensure improved quality and safety of strawberries and lettuce after harvest, the present study applied a modified atmosphere packaging (MAP) technology (Mostofi et. al., 2008). Going forward, it compared the quality and safety of the two products while being stored in a way that put them in an MAP-applied container and a plastic container at room temperature and 4 degree Celsius.

Beyond the rapid normalization process of patents in software industry, complex legal evolution and rigorous economic arguments underlie the crucial environmental transformation of the industry. In this article, we trace the evolutionary history for the theory and practice of patents in software industry from both legal and economic perspectives. First, we study the legal disputes and cases in light with the underpinnings of patent policy transformation, and then delve into the economic backrounds of the pros and cons for software patents, with special focus on the generic economic peculiarities of software industry. The fact that historical and practical policy and law in Korea have been largely affected from those of USA, and relative deficiency in the law, economics and management literature are the main motivation of the study, and we hope this study to contribute to the decision making of policymakers as well as law and business practitioners.

The usage of jet fuel has been increasing with increasing passenger and logistics movements under globalization. CO₂, which is the main global warming gas from aircraft, was charged about 3.5% of total global CO₂ emissions and 12% of transportation fuel emissions. For these reasons, a lot of governments and the international civil aviation organization (ICAO) are trying to reduce CO₂ emissions via the introduction of bio-jet fuel. In this paper, we showed the jet fuel properties, specifications, and presentative production methods of bio-jet fuel such as alcohol to jet (ATJ), oil to jet (OTJ), gas to jet (GTJ) and sugar to jet (STJ). Also, we described the status of global and domestic bio-jet fuel usage and the policy plan for efficient distribution.

Generation and recycling potential of organic waste in Korea were estimated. Status of organic waste composting and compost utilization also were surveyed to promote the recycling of organic waste. From 1994 to 1997, generation of garbage decreased gradually while recycling rate increased due to positive governmental strategy. During the same period, livestock waste increased 11.2%. Municipal wastewater sludge was generated 3,500 ton/day which was 0.03% of wastewater treated in 1996. The energy Potential of industrial organic waste was estimated to 288 million TOE which was 1.75% of the nationwide first energy consumption in 1996. Recycling of industrial sludge was low to 31%, while recycling of animal waste, plant scraps, and wasted paper were relatively high over 50%. Industrial sludge should be recycled more as it was the most part of industrial organic waste. Conventional composting materials were mainly livestock waste, food processing waste, fishery waste, sawdust, and nightsoil. Garbage and sludge have been composted recently. 420,000 tons of compost in 1996 were produced by 288 makers, the most of which were utilized in agriculture. It was suggested that separated collection, compost standard, and quality management should be provided to promote the composting of organic waste.

The Korean military supplies industry tends to become limited in terms of its development to specific areas in line with strategic promotion policies of the local private direct industrial site. However, the relation between base and small cluster is getting lower of the local industrial site. In this study, information related to authorized test reports for munitions was collected through the military quality information system and subjected to social network analysis(SNA). SNA was performed through the relationships among defense quality assurance agencies, test institutions, contracts and cooperative firms through UCINET's Two-Mode Network. In the field of weapon systems, the median technology industry, and the test analysis dependent are high in Seoul, so the analysis revealed that strengthening the infrastructure for test analysis is needed. Also, it was deemed necessary for government-driven political support. Besides, the field support system was efficiently utilizing a relatively local test analysis. It was analyzed that they are overcoming the regional boundaries of small clusters by strategically changing their contract and cooperative firms' status. The research found some spatial inconsistencies between base and small clusters in the military supplies industry, and it was judged that a political suggestion was needed.

Recently security is being an important issue in almost every field of industry. This situation has affected port logistics industry deeply. Ports are now leaving operational methods that only focus on productivity, and shifting to new ones which focus on safety and customer services on the basis of it. Thus a lot of companies and institutions have offered various solutions as this issue becomes more and more intense. Among them, most typical solutions involve installing special devices to ordinary containers to improve its security, such as CSD (Container Security Device) of GE (General Electric) and eSeal of Savi Networks. On the other hand, these devices focus only on international standards or technical implementation, and this causes inconvenience to actual users like cargo owners, sea carriers, or stevedoring companies. This is considered to be due to lack of sufficient consideration on user demands. This research uses QFD (Quality Function Deployment) method for deducting system requirements in order to solve the problems of previous security devices and to develop a security system that can not only reflect the demands of the users but also considers real-world conditions. According to the QFD results, a total of 21 system CTO's were deducted under 5 categories.

본 연구는 파슬리 등의 야채를 첨가하여 제조되는 화이트소시지의 물성 및 저장성에 미치는 자두 분말의 효과를 조사하기 위해 실시되었다. 물성의 변화로서 pH는 자두의 첨가율이 증가함에 따라 상대적으로 감소 하였는데 3% 첨 가시 전 저장 기간 중 가장 낮게 ($pH\;5.11\;{\sim}\;4.44$) 나타났다. 육색(meat color)은 자두의 첨가량에 비례하여 적색도(redness)를 나타내는 a-value에서 높게 나타났으며 명도 (light ness)를 나타내는 L-value에서는 상대적으로 낮은 수치를 보여주었다. 전단력(Shear stre ngth) 측정에서는 저장 기간 중 자두 분말의 첨가량에 비례 하여 근소한 차이를 나타냈는데 저장 7일째에서 가장 높았다. 자두 분말 첨가구 에서의 다소 높은 전단력의 결과는 보수력 (WHC) 측정 에서도 같은 경향을 나타내었는데 자두 분말의 증가량에 따라 3% 첨가구가 대조구 (0%)보다 낮게 나타나 약한 보수성을 보여 주었다. 저장성에 미치는 결과로서 총세균수의 측정결과 저장 3일이 경과한 구간에서 Sorbic acid (0.07%)의 첨가구와 자두 분말(3%) 첨가구 에서 비슷한 항균 효과를 나타내었다. 이 같은 동일한 수준의 항균 효과는 저장 9일째에도 같은 경향으로 나타났다. VBN 측정에는 저장 기간에 따라 증가된 수치를 나타냈는데 저장 7일 및 8일, 9일째 측정 결과는 3% 자두분말 첨가구와 0.07% Sorbic acid 첨가구 와 비슷한 수준을 나타내어 동일한 저장효과를 보여 주었다. 관능검사 실시 결과 총체적인 풍미에 있어서는 자두 분말 첨가구 1.5%가 가장 우수 했으며 다음으로는 3%, Sorbic acid 첨가구 및 공시료 순으로 나타났다.간에 유의차는 나타나지 않았다.pm을 spiking한 후 SPE상에서 SCX(Strong cation exchange column)을 통한 clean-up과정을 거친 후의 STP의 limit of quantification(LOQ)는 약 0.44ppm이었으며, 이에 대한 회수율은 89.7${\pm}$2.3%(n=6)를 나타냈다. 실제 CODEX에서 권장한 우유의 MRL이 0.6ppm인 점을 감안하면 CODEX권고치에 도달할 수 있는 것으로 판단되었다. 따라서 본 연구에서 개발 된 시험법은 지금까지 국내적으로 STP에 대한 시험법이 확립되어 있지 않은 것으로 이와 아울러 간편한 parallux와 병용해 STP에 대한 정량 및 정성 분석을 유도체화 장치 및 형광검출기를 이용해 잔류항생물질 STP에 대한 분석시험법을 개발하였다.화와 네트워크 조직망 구축을 위한 지역중심의 복합 생활문화 공간이 필요할 것이며, 이를 촉진키 위한 mentor academy시스템 접근을 통해 점점 고령화되어 가고 있는 재래시장에 대해 차별적 특성이 반영된 종합적이고 체계적 접근 방법연구가 필요하다./TEX> 자체기술개발, 선진기술 도입, 산업간 및 산업내 기술확산, 국제기술협력 ${\rightarrow}$ 기술혁신의 촉진 ${\rightarrow}$ 총요소생산성과 기업경쟁력(자원 및 역량, 프로세스 경쟁력, 품질경쟁력, 시장경쟁력, 고객성과, 시장성과, 재무성과)의 제고 ${\rightarrow}$ 가격경쟁력(임금, 금리, 물류비용, 환율 등)과 비(非)가격경쟁력(디자인, 에프터서비스, 품질, 운송 등)의 제고 ${\rightarrow}$ 국가경쟁력의 제고 ${\rig
