The overseas military education, which began in 1948, and the commissioned education of professional degrees, which was implemented in 1958 to obtain a degree for a professor at the Korea Military Academy, are expected to be expanded further in order to nurture talent who will lead the future and transformation of the Army in the era of the fourth industrial revolution. However, the Army's commissioned education system has been criticized for being high-cost and low-efficiency, and the systematic evaluation of the performance of commissioned education has also been insufficient. Therefore, this study examined the transition process of commissioned education by the ROK Army. The validity of the assessment area the CIPP evaluation model for the performance evaluation of commissioned education in the Army was verified through expert Delphi survey. According to the Delphi survey, the validity of the assessment area for the performance evaluation was all appropriate and various opinions on commissioned education were obtained.

Jeongrimsaji as temple remains of Baekje Sabi period, its re-excavation has been carried three times in full scale. As a result, the buildings in left and right of lecture hall was largely identified in 3 forms. First, layout of small buildings in left and right of lecture hall. Second, layput of corridor in left and right of lecture hall. Third, layout of construction site in the north of corridor in left and right of lecture hall. Above second is included into remains of Gorye, the third is included into remains of Baekje - the remains were almost ruined then. The first form and third form in above is different each other in size of buildings, form of layout, and location. It is important to investigate these points: the time of constructing the buildings; what position have the use and function of the buildings in the temple? ; transition process of layout of the Buddhist temple. In this context, of temple remains in Baekje during the 5~7th century, the cases where construction sites in left and right of lecture hall and construction site in the north of corridor are identified, have been reviewed. Based on this review, the use and function of buildings, their transition process were investigated. The survey results show that small buildings in left and right of lecture hall existed in the middle and later period of the 6th century. During the later 6th century ~ the 7th century, construction site in narrow and long square shape was located in left and right of lecture hall instead of small buildings in the north of corridor. Therefore, it is identified that the aforementioned thing is earlier stage and the latter thing is later stage.

The main purpose of this paper is to understand the process of the poverty exit across generations through the live experience based on the grounded theory analysis of the in-depth interview. We find that poverty means a lack of achievement and freedom of agency that is a level of control about resource and situation. So exit of poverty across generations is the state that is not only to achieve functioning but also to recover capabilities. Based on this result, central phenomena of the intergenerational exit process of poverty are support from relation and continuous transition at each stage in life. Even if this central phenomenon is an important event, it has the incomplete attribute. Because support from relation is beyond individual scope of control and participants can't escape second labor market as they don't have enough time in the process of transition. Therefore, this paper suggests that the expansion of state welfare and strategy should support transition as policy priorities to minimize limitation of relation and risk of income loss.

For the transition to the low carbon society, it is inevitable but difficult journey that the new energy technology spread co-exists with formal social system. The objective of offshore wind power plant that has been implemented by the government is to connect large capacity new renewable energy to the central electric power system. Therefore, for the successful introduction of offshore wind power system, the transition of the formal social technology system should be companied. This study analysis the energy system transition about niche strategy adjustment using Multiple Level Perspectives & Strategic Niche Management. It also multi level analyzes and structuralizes the process that new technology, as a research result, evolves through connecting and communicating with formal regime and landscape. Also, adjusting Strategic Niche Management, it diagnoses the obstructive factors in the initial stage of niche experiment and found the major reasons why offshore wind power test plant had been delayed. Through this study, it reaches to the practical implication that offshore niche technology could grow stably in the energy system and various policies.

A mechanistic model for forced convective transition boiling has been developed to predict transition boiling heat flux realistically. This model is based on a postulated multi­stage boiling process occurring during the passage time of an elongated vapor blanket specified at a critical heat flux condition. Between the departure from nucleate boiling (DNB) and the departure from film boiling (DFB) points, the boiling heat transfer is established through three boiling stages, namely, the macrolayer evaporation and dryout governed by nucleate boiling in a thin liquid film and the unstable film boiling. The total heat transfer rate during the transition boiling is the sum of the heat transfer rates after the DNB weighted by the time fractions of each stage, which are defined as the ratio of each stage duration to the vapor blanket passage time. The model predictions are compared with some available experimental transition boiling data. From these comparisons, it can be seen that the transition boiling heat fluxes including the maximum heat flux and the minimum film boiling heat flux are nil predicted at low qualities/high pressures near 10 bar.

In this paper, we consider a multistate survival model which incorporates covariates and contains two illness states and two death states. The underlying stochastic process is assumed to follow nonhomogeneous Markov process. The estimates of survival, transition and competing risks probabilities are given via the methods of partial likelihood and nonparametric maximum likelihood. Our discussion is based on the statistical theory of counting process. An illustration is given to the data of patients in a heart transplant program. The goodness of fit procedures are also discussed to check the adequacy of the model.

This study deals with the development of wire path searching module as a part of automobile wire harness design system. Wire path searching module manages the free space, finds transition locations, and creates bundle paths to dramatically reduce a tedious iterative routing process which results in easy optimization of the bundle paths. A prime policy in the system configuration is to compromise between man's and computer's ability, and make it possible a designer's leading role in designing process. Human input is indispensable to cope with the special cases which were not considered in the initial design stage of the system. In this study, we improve the previous shortest-path-finding algorithm, (VGraph and RCA method) into a new method called Extended RCA. Bundles, connectors and transitions are handled as objects so one can manage and modify physical properties of the objects easily. Therefore a verification is allowed at any desired stage of design. The reuse of previous result is facilitated by using Dependency Structure, which represents the mutual relations among connectors, transitions, and bundles. Dependency Structure makes it possible the elimination of redundant calculating process, and consequently shorter routing time.

We propose an approximate algorithm to analyze the queuing system with n bursty and heterogeneous arrival processes. Each input process is modeled by Interrupted Bernoulli Process(IBP). We approximate N arrival processes by a single state variable and subsequently simplify the transition probability matrix of the Markov chain associated with these N arrival processes. Using this single state variable of arrival processes, we describe the state of the queuing system and analyze the system numerically with the reduced transition probability matrix. We compute the queue length distribution, the delay distribution, and the loss probability. Comparisons with simulation data show that the approximation algorithm has a good accuracy.

Purpose: The purpose of this study was to identify the effectiveness of smoking cessation education using the transtheoretical model on the process of change, smoking temptation, decisional balance and stage change transition. Methods: A nonequivalent control group non-synchronized design was used for this study. The study population was 44 male college students in the experimental group and 66 students in the control group. Smoking cessation education was administered to the experimental group at one university. Descriptive analysis, t-test, and ANCOVA were used with the SPSS 19.0 program to analyze the data. Results: After providing a smoking cessation program, the experimental group showed significantly higher scores for self-efficacy for smoking cessation, process of change, and a lower score in decisional balance for pros of smoking and nicotine dependancy compared to the control group two weeks after the pre-test. However, no significant differences were found at four weeks after the pre-test. Conclusion: The findings indicate that this program could have a positive effect on process of change, decisional balance and stage transition for college student smokers.
