In this research, we performed a SWOT analysis to analyze the feasibility of cultivating tropical fruits in Korea, using the mango as a case study. The opportunities for domestic tropical fruit (mango) cultivation are that the domestic cultivation environment is improving due to global warming, the consumer market is expanding due to the increase in domestic demand, and some local governments are supporting the cultivation of tropical fruits as a new high-income crop. The strengths are that it is possible to produce high quality fresh fruits in Korea and that they are still distributed in small quantities, so they can be differentiated from imported ones. There are regular customers and the mango is recognized as a medicinally functional fruit. The threats are that the price competitiveness of imported goods is likely to be further strengthened due to the implementation of the FTA and that it is difficult to cope with the unpredictable climate changes, such as heavy snowfall and extremely cold weather. The weak points are that the initial investment cost is high, the operating costs such as heating bills are also very high, and there is no supply system for the chemicals, fertilizers and cultivation technology required for tropical fruits. In order for tropical fruits such as mangoes to become major fruits, we must make full use of these strengths and opportunities while, at the same time, complementing the weaknesses and eliminating the threats in the value chain.

This study was done to develop indicators for cities that can be used in the long term and in a sustainable manner. Activation indicators were developed to improve the resilience in the downtown area of Seo-gu, Incheon. Preliminary indicators were derived from prior studies on similar indicators of resilience for urban regeneration, and an expert opinion survey was conducted to analyze the suitability and importance of the indicators. Activation indicators were established for improving urban resilience in six areas: population stability, social inclusion, industrial diversity, local productivity, environmental sustainability, and social-based convenience. From 60 preliminary indicators, 42 indicators were selected through the expert opinion surveys for securing an economically active population, establishing a living infrastructure, improving the settlement environment, and upgrading industry to reflect the characteristics of the West, including industrial complexes. It was found that diversification is necessary. Further study is still necessary to improve the objectivity of the indicators and calculate a resilience index. The significance of this study is that it looks at quantitative indicators, complements other studies on regional decline diagnosis, and presents realistic alternatives suitable for domestic situations based on the concept of resilience.

Drones, which show strong growth in the fourth industry, are commonly used for disaster response. In the event of an actual disaster, local governments should carry out 13 cooperative functions to respond to the disaster, but there are difficulties in collecting on-site information in places where it is difficult for people to access or grasp the situation. Based on the 13 collaborative functions that are essential for operations in the event of a disaster, a utilization plan of highly utilized drones was derived. Through the analysis of overseas cases and drone utilization by each department, a total of 10 out of 13 collaborative functions of the Disaster and Safety Countermeasures Headquarters (disaster situation management, emergency life safety support, emergency recovery, disaster resource support, traffic measures, medical and quarantine services, disaster site environment maintenance, social order maintenance, search, rescue, and emergency) were derived. These results can enhance the efficiency of the disaster response by presenting a plan to utilize drone images for each function.

On an absolute straw diet, the effect of graded levels of green grass supplementation on intake, nutrient digestibility, rumen fermentation pattern and microbial N yield has been studied in cattle. Of the two trials conducted, 16 intact growing bulls of 304 kg weight and 32 months old, randomly allocated to four treatments in a completely randomized design in the 1st trial. While, in the, 2nd trial, four rumen cannulated local bulls of about 60 months old and 400 kg weight were used in a $4{\times}4$ Latin square design with four treatments in four periods. In both the trials, in addition to a mineral mixture, animals were supplemented with graded levels of naturally grown green grass of 0 kg (T1), 2 kg (T2), 4 kg (T3) or 6 kg (T4) to an ad libitum rice straw diet In the 1st trial, measurements were made on intake digestibility, growth rate, N balance and microbial N yield. While in the 2nd trial, in addition to the above parameters (except growth rate), rumen parameters were also studied. All levels of grass supplementation decreased the straw DM intake and increased the substitution rate. The rumen $NH_3-N$ concentration increased with the increase in grass level and ranges from 8-46 mg/l. The rumen pH and the rate and extent of DM degradability of straw were not affeceted by different rumen environments created by different levels of grass inclusion. At 48 h, straw DM degradability were 42, 44, 44 and 43% respectively for 0, 2, 4 and 6 kg grass supplementation daily. The whole gut digestibilities of DM, OM and ADF increased significantly (p < 0.05) only at 6 kg level daily. The microbial N yield was not affected by the levels of grass supplemented. The mean microbial N yield was 10 (SD 3.7) g/kg DOM apparently fermented in the rumen. The estimated minimum N loss and thus the maintenance requirement of tissue protein was 303 mg/kg $W^{0.75}/d$. All the animals lost live weight but 6 kg grass supplementation gave positive energy and N balances. Small amount of green grass supplementation is often recommended for optimization of rumen environment of a straw diet However, under the present experimental condition, no such beneficiary effect observed up to 6 kg (26% of DM intake) level of supplementation.

Objectives The number of marriage immigrant women has been increasing in the past several years in Korea and their adaptations to the new environment have been an important social issue. The aims of this study were to evaluate the psychosocial and mental health statuses of Vietnamese marriage immigrant women (VMIW). We intended to compare the mental health of VMIW with married Vietnamese women living in Vietnam and reveal the demographic or psychosocial factors affecting their mental health. Method Subjects comprised one-hundred-forty-three VMIW who enrolled in multiculture family support centers in Chungbuk Province and forty-eight women from Vinh Phuc province in Vietnam. Marital satisfaction, domestic violence and social support were evaluated as psychosocial factors, and the Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI) and General Health Questionnaire (GHQ) were used to evaluate mental health. Results VMIW had a larger age gap with their husbands but better psychosocial statuses. BDI (p = 0.20), BAI (p = 0.08), GHQ (p = 0.13) scores of VMIW were not significantly different compared to Vietnamese residents. Marriage duration of VMIW affects significantly their marital satisfaction, social support and depressive levels (p < 0.01). The level of domestic violence showed a significant difference according to the educational levels of their husbands, composition of family members and marriage process (p < 0.05). VMIW with older husbands and jobless VMIW had low levels of anxiety (p < 0.01). Conclusion The results suggest that VMIW have no difference in mental health compared to Vietnamese women living in Vietnam which is contrary to general expectations. However, various environmental factors, such as marriage duration, have an effect on the mental health of VMIW. As marriage duration is proven to be important factor on mental health of VMIW, more extended duration of care and interventions are needed to maintain good mental health. Networking system connecting mental health screenings by the multiculture family support center to the local mental healthcare center is needed to care those with poor screening outcomes.

The purpose of this project is to create small parks in elementary schools in order to improve the educational environment and also to increase the amount of greenspace in the city. Above all, the main goal is to create space for local residents in which they can enjoy their leisure time. During a basic investigation and document investigation of elementary schools in Daegu, I placed the priority on choosing the schools that showed the most promise. Also, by doing a survey about the present conditions at schools, I verified, compared, and analyzed the validity of creating small parks in elementary schools. The summary of the results are as follows. The average area available for building small parte in Daegu elementary schools is $7,447m^2$. Even though this area is not as large as a neighborhood parti the difference is not that great. Therefore, I assumed that building small parks in schools would be as effective as building neighborhood parks. The standard size for a children's parks is $1,500m^2$, and if small parks were to be constructed in all school areas with available space larger than a children's park (i.e., larger than $1,500m^2$), the amount of added park greenspace would equal $1,217,953m^2$. The number of schools with areas under $1,500m^2$ is only 3% of all schools in which small parte can be created(5 schools). Schools that have between $1,500m^2$ and $8,000m^2$of greenspace make up 59.7% of all schools in which small parte can be created (98 schools). Schools that have greenspace of more than $8,000m^2$ make up 37% of all school in which small parks can be created (61 schools). The standard area for neighborhood parte is $10,000m^2$ (building-to-land ratio 20%). Schools that have areas that are larger than the standard area for neighborhood parte make up 31% of all elementary schools in Daegu (61 schools). Therefore city greenspace would increase to a total of $694,805m^2$ by making use of these schools, which would represent 7% of the park greenspace in Daegu.

According as mobile computing environment is generalized by development of wireless networking technology and communication device, mobile host uses local cache for extensibility and early response time. and reduction of limited bandwidth. This time, between mobile host and mobile support station cache need consistency interested person of done data accordingly much techniqueses propose. Existent consistency techniques because detection based techniqueses are used mainly and broadcast periodic invalid message considering frequent disconnection. However, these techniqueses increase abort step through increase or delay of transmission message number by accuracy examination of data. Therefore, because mobile host deletes cached data, and extensity are decreased. Techniques that is proposed in this paper did to perform refering update frequency about object that page request or when complete update operation happens to solve these problem. Therefore, have advantage that response is fast because could run write intention declaration or update by update frequency electively asynchronously when update operation consists and abort step decreases. Also, improved extensity running delete or propagation electively according to update frequency about periodic invalid message gone since disconnection.

Mobile Edge Computing(MEC) is a emerging technology to cope with mobile traffic explosion and to provide a variety of services having specific requirements by means of running some functions at mobile edge nodes directly. For instance, caching function can be executed in order to offload mobile traffics, and safety services using real time video analytics can be delivered to users. So far, a myriad of methods and architectures for personalized service recommendation have been proposed, but there is no study on the subject which takes unique characteristics of mobile edge computing into account. To provide personalized services, acquiring users' context is of great significance. If the conventional personalized service model, which is server-side oriented, is applied to the mobile edge computing scheme, it may cause context isolation and privacy issues more severely. There are some advantages at mobile edge node with respect to context acquisition. Another notable characteristic at MEC scheme is that interaction between users and applications is very dynamic due to temporal relation. This paper proposes the local service recommendation platform architecture which encompasses these characteristics, and also discusses the personalized service recommendation mechanism to be able to mitigate context isolation problem and privacy issues.

This study analyzed factors that should be considered in the process of export diversification strategy formulation and priorities of strategies. We reviewed the extant literature and interviewed six experts. Cross-sectional analysis of a literature review and interview results were used to determine the influencing factors of export. The data for this study were collected from a survey of 68 export experts in Automotive Parts enterprises. Data were analyzed using AHP. As a result of the analysis, the order of importance appeared in the order of internal capacity, correlation buyer effect, entry barriers, technology response, and competition environment. The regions with a high overseas level were product differentiation, centralization, and low cost, whereas those with a low level were in the order of low cost, product differentiation, and concentration. It is meaningful to review the alternatives for adoption of the export diversification strategy and establish a strategy appropriate to the situation. It is necessary to establish a customized strategy considering the characteristics of the global region, and not only internal competence but also mutual relationship with local buyers are important.

The wireless low-floored tram is an innovative transportation system which is environment-friendly and highly energy-efficient. In addition, the system has various advantages such as low construction cost, improvement of urban landscape, revitalization of surrounding commercial area, elevated convenience for passengers, etc. Therefore, more than ten local governments have proposed tram construction projects in Korea. Accordingly, many research and development projects are ongoing funded by government including the developments of tram vehicle, tram trackway, signal system, etc. The embedded rail system are commonly used in order to provide leveled roadway surface in urban area. It is effective to reduce the noise and vibration, caused at the interface between the wheel and track, to minimize the construction period, and to lower the maintenance cost. This paper investigated the design and construction processes for tram trackway and figured out the constructability for the test track with embedded rail system for the first time in Korea. The performance to reduce the noise and vibration were quantitatively measured in the test track with embedded rail system. In addition, the results were compared to the ones for track with conventional rail system.
