This study was to explore experiences of Female Ex-offender's re-entry process to socialization. For this, 9 female ex-offenders who receive housing support by the Korea Rehabilitation Agency were interviewed and the Strauss and Corbin's ground theory is used to approach to the data. In open coding, 88 concepts, 33 subcategories, and 15categories emerged from the data. In axial coding, central phenomenon were 'indulge in self pity', 'being isolated female ex-offender'. Intervention condition was 'human cooperation system'. Strategies were 'increase the receptiveness', 'establish the foundation'. Consequences were 'finding the stability in the life', 'changing the life direction'. In selective coding, main theme was 'overcome social stigma through changing life-direction and acclimate to society', and four phases were derived from the data. Based upon this results outcome, need of female ex-offender in the process of social transition and their experience were discussed.

This paper analyze technical review entry criteria and review process based on system property, and review checklist to conform technical review is also showed. The execution of review is determined according to the preparation of review item and identification for risk element. Risk level should be mitigated before technical review by appropriate plan. This paper described the entering condition of technical review for developmental phase, and tailoring consideration for technical review condition. Described technical review entry criteria, review process, and tailoring consideration is applied to development of test equipment for ground ant-air missile system. Applied system specific technical review process, tailored entry condition for test equipment for ground ant-air missile system and review check list is showed and the effectiveness of described system specific technical review process is presented.

Signalized intersections are widely used in urban street network. However, it was reported that a roundabout is better than a signalized intersection in terms of delay when the approaching traffic volume for each bound is low. The objective of this study is to develop entry capacity models of roundabout and establish the warrant for signalized intersection based on the delay. The entry capacity of a roundabout is determined by the circulating traffic volume and the geometric design of the roundabout such as the diameter of central island, entry lane widths, and the circulating roadway width. The traffic and geometric characteristics of four roundabouts were collected and analyzed. The study reveals that; i)among the geometric features, the diameter of central island and the circulating roadway width influence the entry capacity, and ii)even though it is difficult to compare the models of each country due to different geometric features considered in the models, the models developed in this study show higher capacity than the models from Israel or Germany. These seem to be attributed to the facts that; i)the outside diameters of the roundabouts selected in this study are larger than in the other studies, and ii)the acceptable gap in Korea is smaller than that in the other countries. In order to compare the performances of round- about and signalized intersection, the performance of roundabouts was evaluated with the SIDRA. The simulation was conducted only for the roundabouts composed of single lane. According to the result of the analysis, it may be concluded that when the approaching traffic volume for each bound is lower than 600pcph, a roundabout is better than a signalized intersection in terms of its operational performance.

The approach and landing phase of a re-entry vehicle is composed of Steep Glideslope phase, Circular Flare phase, Flare Maneuver phase. The trajectory planning algorithm with geometric parameters is studied in this paper for on-board trajectory planning. This algorithm generate reference trajectory rapidly considering safe landing of re-entry vehicle. In this paper, the Mamdani Fuzzy PD type controller for longitudinal and lateral control is designed which has robustness of nonlinear system. In addition, the simulation is performed including initial downrange and crossrange errors, and the results shows that the proposed fuzzy logic controller has good performance.

본 연구의 목적은 N사의 파트너스퀘어(광주) 이용한 경험이 있는 청년자영업자를 대상으로 e-커머스 창업생태계인 온라인쇼핑몰에 진입하는 과정과 성과를 근거이론(Grounded Theory) 방법을 활용해 규명해 보는 데 있다. 본 연구는 심층 면접 조사 자료를 활용했는데, 연구 참여자의 선정에 있어 이론적 표본 추출(Theoretical Sampling)방식을 사용했으며, 스트라우스와 코빈(Strauss & Corbin)이 제시한 개방코딩, 축코딩, 선택코딩 순으로 진행한 후 패러다임모형으로 분석했다. 주요연구결과는 다음과 같다. 첫째, 부모가 e-커머스에 대해 잘 알지 못하거나 부정적이라도 자녀의 창업에 대해서 긍정적이면 자녀가 온라인쇼핑몰을 통한 자영업에 진입하는 것으로 나타났다. 그러나 부모가 e-커머스에 부정적이고, 자녀의 창업에도 부정적이면 자녀는 온라인쇼핑몰을 통한 자영업에 진입하지 못하는 것으로 나타났다. 둘째, 청년층의 e-커머스를 통한 자영업 진입과 성과 창출조건으로 e-커머스 활용능력이 중요한 것으로 나타났는데, 특히 N사의 파트너스퀘어(광주)는 e-커머스 활용능력을 증대시켜, 청년층이 온라인쇼핑몰을 통한 자영업 진입에 긍정적 영향을 주는 것으로 나타났다. 셋째, 청년층은 온라인쇼핑몰을 통한 e-커머스 자영업에 진입한 이후 단순한 매출액 증가 이외에 자존감 상승, 기회발견, 창의성 역량이 강화되는 것으로 나타났다.

This paper deals with the world civil helicopter market scope, world market analysis based on the operating fleet ages, preconditions for market entry, and market forecast which are necessary for Korean industry to enter into world market. According to the analysis, the heavy single class demand is rapidly declined. The demand is moving toward the heavier class than that operated now. Korean industry had better have strategic positioning to heavy twin and light medium twin classes. A considerable amount of Korean civil helicopter based on Surion can be sold if there are appropriate efforts for price, specification, marketing strategy and so on.

The re-enty guidance design involves trajectory optimization, generation of a reference drag acceleration profile with the satisfaction of trajectory constraints. This reference drag acceleration profile can be considered as the reference trajectory. This paper proposes the atmospheric re-entry system which is composed of longitudinal, later and range control. This paper shows the a performance of a re-entry guidance and control system using feedback linearization control and predictive control.

This paper compares the relative performances of area and cordon tolls as opposed to the first-best congestion tolls with respect to alleviation of traffic congestion and social welfare. The comparison is done in the monocentric city where all the jobs are located at the city center. The study shows that the size of charging zones is similar in the two second-bests, but that the optimal toll level is higher in area pricing than in cordon pricing. Area pricing schemes turn out to perform better than cordon pricing schemes as measured by average speeds and daily average travel time. Accordingly, the former is shown to increase the social welfare more than the latter. In the case of the cordon tolls, the residents at the charging zones are exempted from the tolls. In this way, cordon tolls invite people into the most congested areas over the optimal level while partially negating the whole spirit of the congestion tolls.
