이 글에서 살펴본 바는 다음과 같다. 1) ISO 10646-1 한글 부호계의 운용 방안은, 앞으로 얼마동안은 2,350 완성형 소리마디를 쓸 수도 있겠지만, 길게 보아서는 첫가끝 부호계 238 글자로 통일하는 것이 바람직하다고 본다. 2) ISO 2022 틀을 따르면서 한글을 완벽하계 지원하는 한 바이트 한글 부호계를 개발하여, 국제 등록부 (International Register) 에 등록하여, Escape Sequence을 받아서, ISO 2022 를 따르는 분야에서 쓸 수 있도록 하여야하겠다. 3) ISO 10646-1 을 개정하여 4,516 소리마디를 넣자는 안은, 완성형으로만 한글을 지원하게 되어 바람직하지 않다고 본다. 모아쓰기 글자를 지원하는 세계 추세가 조합방식이므로, 10646-1 을 현재대로 두고, 첫가끝 방식의 238 글자를 쓰는 것이 바람직하다고 본다. 4) 10646-1 을 재대로 지원할 수 있는 세벌식 자판을 정부의 복수 표준으로 채택할 것을 제안한다.

Objectives: This study identified the labor union associates' perception and participation status on SHEW and analyzed these two Constructs correlations with Safety and health education at work(SHEW) in manufacture and construction industries. Methods: Self-administered survey was successfully finished by 103 labor union associates (91 employed in 78 manufacturing companies and 12 employed in 12 constructing companies over 12 areas). Two questionnaires, survey direction slip, the official letter to ask survey participation from Korea Ministry of Labor, and a posted envelop to return were delivered to each workplace labor union office in conveniently selected companies. Most participants' companies were at least medium to large in manufacturing industry and most associates were men and married. A survey questionnaire examined demographic characteristics, SHEW status (participation status included), and perceptions of SHEW. Results: Overall, manufacturing companies had better infrastructures for SHEW, employer support for SHEW, and current educators' competencies than constructing companies. These infrastructures for SHEW were closely correlated with company labor union participation on SHEW and the correlation coefficients were greater than any other expectations or needs variables for SHEW. Conclusions: The primary strategies for better participation and support from labor union need to be developed in supporting for organizational infrastructures related to SHEW and strengthening safety and health education training programs for supervisors or educators at work.

This study presents a systematic procedure for developing a short-term prediction deep learning model of rebar price using bidirectional LSTM, Random Search, data combination, Dropout. In general, users intuitively determine these values, making it time-consuming and repetitive attempts to explore results with good predictive performance, and the results found by these attempts cannot be guaranteed to be excellent. With the proposed approach presented in this study, the average accuracy of short-term price forecasts is approximately 98.32%. In addition, this approach could be used as basic data to produce good predictive results in a study that predicts prices with time series data based on statistics, including building materials other than rebars.

It is unique from other financial institutions that credit unions in Korea have been developed as voluntary activity for enhancing the financial access of the poor in 1960s. However, currently some raise criticism that the cooperative identity as voluntary movement has been weaker. This paper endeavor to analyze the growth of credit unions during 2000s and explain what the implications of their growth are, using data from National Credit Union Federation of Korea. Our findings are as follows; firstly, the development of credit unions in 2000s are able to be regarded as a reflection of the rationale of advocate for quantitative growth. Secondly, the growth of credit unions are mostly dependant on non-taxable deposit, large loan, and collateralized loan which can lead to weaken the identity as voluntary cooperatives. Thirdly, the strategy of quantitative growth cannot be helpful for soundness of asset and profitability, eventually weakening their sustainability.

Producer and distributor of electrical and electronic equipment may directly collect waste electrical and electronic equipment that falls under the class to which the equipment they distributed belongs, or may join KERC(Korea Electronic Recycling Cooperative) and have KERC fulfill the duty to collect on behalf. In this study, the system of calculating the financial contributions is reviewed, and then the defined problems and improvement plan are proposed. First, the standard operation and time should be set for collection and transportation costs, taking into account the operation by collection type. Second, since there is a difference in the screening method of the recycling center, the standard cost for the allocation factor should be set by reflecting the difference in these methods and the characteristics of the product line being processed. Third, it is necessary to secure a budget of sufficient size by determining the median or average value rather than the minimum value in the forecast model for visit collection. This study is suggesting in that it examines the problems of the allotted contributions paid by the mutual aid members to KERC and suggests ways to improve them.

In recent years, the web services composition search has become an issue of great interest. The web services composition search is the process of integrating individual web services to yield desired behavior. Through the web services composition search, more sophisticated functionalities can be provided. Current solutions can be classified into three main classes: forward chaining approach, backward chaining approach and two-phase approach. However one-way chaining approaches, such as forward chaining approach and backward chaining approach have limitations of searching irrelevant web services. And two-phase approach has limitations of including redundant web services. In this paper, we propose an unredundant web services composition search based on the two-phase algorithm. The algorithm consists of a forward phase and a backward phase. In the forward phase, the candidate web services participating composition will be found efficiently by searching the Link Index. In the backward phase, unredundant web services compositions will be generated from candidate web services by using the Token Manager. The experimental results show that our proposed algorithm is more efficient than one-way chaining approaches. The experimental results also show that our algorithm can provide more solutions than previous two-phase approach and is comparable to previous one in execution time.

This study examines labour market and unemployment protection policies as a configuration in 12 OECD countries in order to investigate how countries from different regime conform to or diverse from previous welfare state regime discussion, and to examine its relationship with poverty and inequality. In analyzing the combination of the unemployment insurance, the unemployment assistance, and active labour market policy, firstly, fuzzy scores of unemployment insurance was calculated by analyzing the strictness of eligibility, duration of benefit and the generosity of income replacement rate. For unemployment assistance, the ratio of public assistance expenditure to the GDP in each country and the ratio of unemployment benefit level to the average wage in each country have been considered. As for the active labour market policy, the total expenditure per GDP of this policy was converted into fuzzy points and analyzed. As a result, 5 types in 2005 and 6 types in 2010 were generated. Specifically, 'assistance type(iAp)', 'insurance type (Iap)', 'comprehensive safety net type (IAP)', 'weak safety net type(iap)' were analyzed. This paper suggested policy implication for South Korean case, which consistently had high score for weak safety net type(iap).

Semantic service can be defined as the service providing search API or reasoning API based on ontology and Web Services. It performs a pre-defined task by exploiting URI, classes, and properties. This study introduces a semantic service composition method based on a semantic broker referring ontology and management information of semantic services stored in a semantic service manager with requirements of the user. The requirements consist of input instances, an output class, a visualization type, semantic service names, and property names. This composition method provides dynamically generated semantic service pipelines including composit semantic services. The user can execute the pipelines provided by the semantic broker to find a meaningful semantic pipeline. After all, this study contributes to develop a system supporting human service planners who want to find composit semantic services among distributed semantic services.

This paper, using the sample of male workers in manufacturing industry from the HCCP (Human Capital Corporate Panel) data, analyzes the effects of trade union on the level and dispersion of wages. One of the advantages of the HCCP data is that it enables a researcher to control the effect of individual firm's 'ability to pay' on wage. All relevant variables controlled, the union effect is estimated to be 5-8%. Yet this figure seriously underestimates the wage advantage enjoyed by union workers, because union sets the "price" for experience low and the price for tenure high and at the same time extends tenure of workers by adopting strong employment protection policy. The paper also analyzes the effects of union on the wage inequality. The results are mixed: overall wage inequality is smaller in union sector while standard deviation is larger when all the personal characteristics are controlled.

In order to investigate the heating performance of multi-heat pump applying an inverter compressor, the experiment on heat pump with 3 indoor units was performed under the heating standard and heating low-temperature conditions. The performance data of heat pump with 3 indoor units were measured by the multi-psychrometric calorimeter. The operation characteristics and the behavior of the refrigerant cycle of the heat pump with 3 indoor units were understood from the heating capacity, heating COP, and P-h diagram by indoor-unit combination. The present experimental results show that the operating load and performance of the multi-heat pump depends on the indoor-unit combination. The heating capacity and heating COP of the low temperature condition were smaller than those of the standard one. Also the refrigerant cycles on indoor-unit combination were analyzed by using P-h diagram.
