For underpasses in Yeongjong Sky City business district, the guided drainage system, as a buoyancy prevention system has been designed, and is under construction. This paper investigates the safety of the guided drainage system for underpass structures being constructed in Yeongjong Sky City business district. This paper also calculates the amount of outflowing groundwater generated by the guided drainage system, and proposes alternative usages of the water. In order to investigate safety and field applicability of the guided drainage system for underpasses, characteristics of the surface flow for the area of interest have been analyzed, and the flow change of groundwater following the underpass structure construction has been evaluated using the 3-dimensional groundwater program MODFLOW. The influence of ground water on safety of the underpass structures has been calculated by FLAC2D analysis. For alternative usages for the outflowing groundwater generated by the guided drainage system, utilization methods of the outflowing groundwater in national and international resources have been researched. The amount of an outflowing groundwater to be generated in the area of interest has been analyzed, and efficient potential usages of this groundwater have been researched. When guided drainage technique is applied, the change in flow of groundwater must be evaluated and considered as safety factor relating to the buoyancy of the structure. As a result, safety factor demonstrated more than 1.2, meaning that the underpass structure is safe. The amount of subsoil drain generated by the guided drainage system was also analyzed. The quality and amount of water satisfied the standards and volume requirements, so as to make it applicable for a number of uses, such as X, Y, and Z, and should prove to be a valuable resource as the circumstances of the neighboring area change over time. These resources can be used as basic data for future urban water circulation studies, as well as generating research of alternative water usages.

A pendulum of industrial education begins to shift from one based on industrialized society to one on information-based age. To produce an effective result in this situation, It is necessary that an accurate estimate of a change in the circumstances of industrial high schools of Gyeonggi-do. This study researched the province's characteristics and countermeasures on industrial education adjusting the change of industrial environments by regional groups and suggested the solutions as follows. First, This study classified Gyeonggi-do into 9 regions considering the region's respective industrial structure and suggested the structure adjustment plan. Second, This study suggested '3-type curriculum management plan' based on the structure adjustment plan of industrial high schools. It includes employment-centered curriculum which provides the human resources required by industrial community, foundation-centered curriculum which revitalizes starting up a enterprises and clears up the manpower problems, college preparation-centered curriculum which meets the need of the students who are much interested in going to the next stage of education. Third, this study suggested a solution to a problem of surplus industry teacher. It includes 3 methods: Increasing practical training from 2 ours to 3 hours, assigning teachers for a task of academic-industrial collaboration and career counseling, qualifying industrial teachers for another course by minor. An amicable settlement on these matters requires a systematic administrative and financial support based on closely connected governmental-academic-industrial collaboration.

Purpose - In a difficult time for a firm, it seems impossible to change circumstances by a firm. Nevertheless, the firm must do whatever it can do by however it can do. Therefore, the purpose of this study is to analyze the effect of HRM practice on organizational effectiveness with the status quo of the firm as a moderator. Based on the result of this study, the managerial implication could be suggested as a contextual response to each status quo of the firm in improving and managing organizational effectiveness by HRM practice. Research design, data, and methodology - This study measured organizational effectiveness with employee satisfaction and organizational commitment. HRM practice includes two HR management areas, HR system, and HR attitude. HR system includes education & training and additional wage welfare. HR attitude includes employee stress and empowerment. As for the status quo of the firm, this study considered three construct; firm feature, strategic feature, environment change feature. This study analyzed 397 employees of 24 company data from the 7th HCCP of KRIVET. Result - Hypothesis 1 through Hypothesis 3 were partially supported. The results of this study suggest that to increase organizational effectiveness(job satisfaction and organizational commitment), employee stress and education & training participation need to be managed. And circumstance of an organization as given the Status Quo of the firm needs to be managed differently like firm size, environment change in demand, and technology. Conclusion - This study suggests best-practice implications based on the result between HRM practice and organizational effectiveness. And also suggest differentiation in management to increase the best-fit in management.

The rapid change in the administrative environment is bringing about changes in the civil service society, and the civil service society is also aware of the difficulty in responding to the changing circumstances of the existing recruiting system, and is attempting to change the new recruiting system. However, in a civil service society that emphasizes stability, it is not easy to change the recruiting system, and it is necessary to examine whether the recruitment of public official in the future is possible by the current recruitment method. Therefore, this study presents the talented people required for the future society through the literature and examines the current recruitment method for recruiting a talented people who meet the future required officials. In this paper, we suggest a four talents in the future : flexible pioneering talents, fused collaborative talents, creative information union talents, and emotional sympathetic talents. And also we will present a direction for the development of the approach.

Most of all the transfer of undertakings in such a service provision business as labour-intensive operation creates uncertainty of employment, aggravates terms of employment and breaks a trade union. However there are no regulations in Korea to protect employees from these undesirable situations. On the other hand Great Britain has introduced the concept of a transfer of undertakings by service provision change in 2006. It was intended to remove or at least alleviate the uncertainties and difficulties created by the need under TUPE 1981 and EU Directive to establish a transfer of a stable economic identity which retained its identity in the hands of the alleged transferee. In contrast to the words used to define transfer in the 1981 Regulations 'service provision change' is a wholly new statutory concept and distinguished from the economic entity. The new provisions seems to be straightforwards and the circumstances in which service provision change is established are clearly set out in Regulations. In this context there is no need for a judicially prescribed multi-factorial approach, as advanced by European Court of Justice like Spijkers test. The new concept of service provision change apply even though there are some minor difference or differences between the nature of the tasks carried on after service provision change as compared with before it. A commonsense and pragmatic approach is required and It is enough only to ask whether the activities carried on by the alleged transferee are fundamentally or essentially the same as those carried out by the alleged transfer. TUPE 2006 of Great Britain far exceeding the scope of the Acquired Rights Directive is full of suggestions as a model of legislation to secure a stable employment itself and favorable and fair conditions of employment. More active efforts are needed for lawmaking to prohibit a dismissal and vary conditions of employment for the reason of the transfer of undertakings itself.

An integrated assessment model of climate and the economy (IAM) has been a standard tool for the economic analysis of climate change and policy recommendations. Since policy measures to address climate change take places at a national level, a regional integrated assessment model of climate and the economy (RIAM) is gaining more importance. A RIAM is a useful tool for the assessment of regional (or national) impacts of climate change. This paper investigates the main features of the currently available RIAMs. The focus is social welfare functions and the regional aspects of climate change. The comparative analysis shows that there is a huge gap between the economics of climate change and its applications to RIAMs. As an application, this paper examines the effect of social welfare functions on optimal solutions of the RICE (Regional Integrated model of Climate and the Economy) model. It is found that optimal climate policy such as carbon tax or emissions control rate is very sensitive to the assumptions on social welfare functions of RIAMs. It is better for each country to have their own RIAM as a basic tool for national climate policy-making and for international bargaining in greenhouse-gas mitigation. This is because a country's own preferences such as efficiency, equity, and sustainable development as well as national circumstances can be reflected in RIAM. The Republic of Korea has not developed its own RIAM yet. The comparative analysis and the numerical model in this paper can be a stepping stone for the development of such a national model.

Climate change is the variation of long term weather pattern based on statistical diversities in terms of natural and artificial factors. Recent numerous extreme weather phenomena have increasingly obtained people's awareness of climate change. Since water resources field especially has higher vulnerability caused by climate variation, the major part of future preparation should be focused on risk minimization of water resources. However, in reality validation of water resources vulnerability is not well built up. For this research, Delphi Method was applied to evaluate middle/small size rivers in Korea with respect to the degree of vulnerability due to the climate change. Delphi Survey is based on iterative, anonymous characteristics with experts' opinion sharing on the given issues. For this study, three iterative surveys were operated for the degree of vulnerability. First round was for selecting vulnerability indicators in terms of the magnitude of total score, and second and third rounds were for collecting experts' idea with opinion convergence. Per the variance of standard deviation of 2nd and 3rd surveys divergence, we clearly see the achievement of opinion agreement. For the future study, we may need to find an applicable field using delphi indicators with various circumstances.

This research was performed to examine changes in the timing of the growth of crops along with changes in temperatures due tochanges and to analyze the change of water-supply-reliability by adding an analysis of the change of agricultural water supply patterns in the basin area of Miryang dam in Korea. Had-CM3 model from U.K. was the tool adopted for the GCM model, a stochastic, daily-meteorology-generation-model called LARS-WG was alsoused for downscaling and for the climate change scenario (A1B) which represents Korea's circumstances best. First of all, to calculate changes in the timing of the growth of crops during this period, the theory of GDD was applied. Except for the period of transplanting and irrigation, there was no choice but to find the proper accumulated temperature by comparing actual temperature data and the supply pattern of agricultural use due to limited temperature data. As a result, proper temperatures were found for each period. $400^{\circ}C$ for the preparation period of a nursery bed, $704^{\circ}C$ for a nursery bed's period, $1,295^{\circ}C$ for the rice-transplanting period, $1,744^{\circ}C$ for starting irrigation, and $3,972^{\circ}C$ for finishing irrigation. To analyze future agricultural supply patter changes, the A1B scenario of Had-CM3 model was adopted, and then Downscaling was conducted adopting LARS-WG. To conduct a stochastical analysis of LARS-WG, climate scenarios were generated for the periods 2011~2030, 2046~2065, 2080~2099 using the data of precipitation andMax/Min temperatures collected from the Miryang gauging station. Upon reviewing the result of the analysis of accumulated temperatures from 2011~2030, the supply of agricultural water was 10 days earlier, and in the next periods-2046~2065, 2080~2099 it also was 10 days earlier. With these results, it is assumed that the supply of agricultural water should be about 1 month ahead of the existing schedule to meet the proper growth conditions of crops. From the results of the agricultural water supply patterns should be altered, but the reliability of water supply becomes more favorable, which is caused from the high precipitation change. Furthermore, since the unique characteristics of precipitation in Korea, which has high precipitation in the summer, water-supply-reliability has a pattern that the precipitation in September could significantly affect the chances of drought the following winter and spring. It could be more risky to make changes to the constant supply pattern under these conditions due to the high uncertainty of future precipitation. Although, several researches have been conducted concerning climate changes, in the field of water-industry, those researches have been solely dependent on precipitation. Even so, with the high uncertainty of precipitation, it is difficult for it to be reflected in government policy. Therefore, research in the field of water-supply-patterns or evapotranspiration according to the temperature or other diverse effects, which has higher reliability on anticipation, could obtain more reliable results in the future and that could result in water-resource maintenance to be safer and a more advantageous environment.
