Four species of green hairstreak butterflies, namely Ahlbergia ferrea, A. tricaudata, A. frivaldszkyi, and A. leei, belonging to the genus Ahlbergia Bryk, 1946 (Papilionidea: Lycaenidae), are examined in Korea. It was discovered that Ahlbergia frivaldszkyi, which was previously incorrectly reported in Korea, is actually A. leei. We report two species, A. frivaldszkyi and A. tricaudata as new additions to the Korean fauna. Detailed diagnoses of these four species are provided, including descriptions of both male and female genitalia, along with a key for identifying the four species found in Korea.

인터넷과 스마트기기의 발달은 시간과 장소에 구애 받지 않는 다양한 분야의 학습이 가능한 환경을 제공하고 있으며 이는 새로운 매체에 최적화된 학습컨텐츠를 필요로 하고 있다. 현재 다양한 IT관련 교육 중 가장 많은 온오프라인 교육이 이루어지고 있는 분야는 오피스 SW 분야이다. 그러나 교수자는 단순한 기능 전달에 중점을 두어 개념을 설명하고, 실무활용과는 무관한 형식적인 예제를 실습한 후 예제에 대한 풀이를 반복함으로써 효과적인 실무활용 교육이 이루어지지 않고 있다. 우리는 RTE(Real Training Environment)시스템이 적용된 LET(Live EduTainer)를 활용하여 학습능력을 극대화할 수 있는 새로운 방법을 제시하고, 단순한 지식전달을 넘어 '재미'와 '흥미'를 유발하여 교육에 대한 '몰입'이 가능하도록 GBL(Game Based Learning)을 접목한 교육시스템을 개발하였다. 본 논문에서는 시스템을 제작하는데 필요한 교수-학습법과 구체적인 솔루션 구성 및 설계과정에 대하여 기술한다. 이를 통해 획기적인 오피스 S/W 교육에 대한 새로운 대안을 제시하고자 하였다.

A planned access method on constantly-changing-community unit plan changes and develops based on the periodical situation and also plan theory. In this research, it is to present the link between the theory of complex city change and the plan factor of it, and to show how Korean residential complex plan has changed as time passed and how new concept of city plan came up and by applying new methods how can this affect our real world and the past plan. In the phase of analysis, it analyzed the flow of 'community unit plan' and its theory and investigated the factor of compositional space and built a analysis frame. The factors of community unit plan are space structure, size and shape of block, population, distribution of facilities and movement system. It chose the place that can represent the flow of community unit plan trand and that indicates the obvious development leading to Jamsil (1975), Gwa Chun (1980), Mok Dong (1983), Sang Ge (1985), Ilsan (1989), Dong tan (2001) and Eun Jung (2003) total of 7 places. And to compare a similar size of the city, it selected a small community unit. Based on the result of theoretical study and prior research, it can be said that the space composition style has change from a whole complete complex area to a linked-cross over community unit and the access of urban level was on set. Also, a pedestrian walking area was secured and the dense of building structure and pleasant environment wanting need was in balance. For facility plans, the usage of facility and functional change brought change of type, size and disposition. The walking area for pedestrian became a huge matter. Therefore, market, education, public facilities and green system collaborated to co-build a whole community unit and activated the walking environment. Also, public transportation, environment friendly city organization was built.

These days, the business environment such as Information Technology (IT) is rapidly changing, and organizations are consistently trying to change themselves for the survival and success under the changing environment. In this situation, change management is very important because it draws the change behaviors of organization members for the success of organizational change. The purpose of this study is to investigate the effect of the organization members' psychological factors on the performance of the acquisition of new IT, which is one of the most important organizational change. Based on previous studies in the area of organizational change, organization members' resistance to change, self-congruity theory, change activities and organizational performance, the research model is developed for validating the effect of organization members' self-congruity on the performance of the acquisition of new IT. Statistical analyses show that self-congruity has a significant effect on the change activities. In particular, private self-congruity has more impact on the change activities than public self-congruity. In addition, self-leadership, rewards and recognitions, and the diffusion of change activities have significant effects on job satisfaction. Self-leadership has a significant effect on organizational commitment.

Slush hydrogen containing liquid and solid hydrogen is expected to achieve zero boil-off by suppressing boil-off gas because heat of fusion for solid absorbe the heat ingress from atmosphere. In this paper, quantitative analysis on storage cost considering specific energy consumption between 1,000 m³ class liquid hydrogen storage system with re-liquefaction and slush hydrogen storage system during equivalent zero boil off period. Even though approximately 50% of total storage capacity should be converted into solid phase during the initial cargo bunkering, total energy consumption to convert into slush hydrogen is relatively 25% less than re-liquefaction energy for boil off hydrogen during zero boil off period. That's because energy consumption of slush phase change take up only 1.8% of liquefaction energy. moreover, annual revenue requirement including CAPEX, OPEX and electric cost for slush hydrogen storage could be more reduced approximately 32.5% than those of liquid hydrogen storage and specific energy storage cost ($/kg-H₂) could also be lowered by about 41.7% compared with liquid hydrogen storage.
