  • Labor market participation and occupational status for workers majoring in(natural) science and engineering are estimated and compared with workers of other majors at three levels: employment, prestigious occupations, and good occupations. For this, we utilized 2% Public Use Sample of 2000 Korea Census. The results of two-stage probit models, which adjust sample selection bias, do not support the argument that graduates of science and engineering majors are relatively disadvantaged. Workers of engineering majors are more likely to have 'good occupations' at their early job careers, but their advantages fade away quickly as they are aging. Especially at their 40s, their probability of having 'good occupations' start to be likely lower than workers of social science majors. This may be due to low human capital accumulation rates at work places along with quickly outdated skills which are acquired in colleges.

  • 본 연구의 목적은 충북대학교 부속농장에서 2009년 영농기간을 중심으로 담수된 논에서의 산화환원전위(Eh)의 변화와 시비에 따라 영양물질인 인(P)의 농도변화 특성을 파악함으로써, 논으로 부터의 인의 유출제어에 관한 기초 자료를 제공하는데 있다. 이 연구는 2009년 5월부터 11월까지 논에서 담수의 총인(T-P)과 인산염 인($PO_4$-P)의 농도변화와 토양의 산화환원전위(Eh)와의 관계 특성을 파악하였다. 관개기의 논에서 인은 분얼비 시기에 인성분이 시비되지 않았는데도 불구하고 T-P농도가 0.68 mg/L로 높게 나타났다. 이는 담수의 영향으로 논이 환원상태로 되어, 논바닥에 침전된 철이온에 흡착되어 있던 인이 철이온의 환원으로 함께 용출하기 때문이라고 생각된다. 높은 Eh는 산화경향을, 낮은 Eh는 환원경향을 나타낸다. 본 연구기간 동안의 Eh 값은 연속적으로 담수되었던 7월 중순까지는 74~112 mV 가량 나타냈고, 그 이후에는 담수상태가 아닌 경우가 많아 179~636 mV로 높게 나타났다. 논 담수의 T-P와 $PO_4$-P 농도는 분얼비 직후 1주일후까지 같이 상승하다가 T-P농도는 약 2주일까지 더 상승한 반면 $PO_4$-P 농도는 하강하였는데 이는 논 토양이 환원상태로 되면서 바닥에 있던 입자성 인이 논 표면으로 떠올랐기 때문으로 사료된다. 그 후에는 담수가 끝나는 시점까지인 농도는 낮아졌다. 관개초기에 인의 농도는 비교적 높게 나타났지만, 7월 이후로는 작물의 생장에 필요한 영양물질 섭취 등으로 인 농도가 낮게 나타났는데 이는 7월 이후의 논은 인의 유출을 억제하고 있는 것으로 추정된다. 또한 논 담수위의 증감에 따른 $PO_4$-P 농도와 Eh 값을 회귀분석 한 결과 각각 정의 상관관계와 부의 상관관계가 있는 것으로 나타났다. 이와 같이 논 담수 및 시비에 따른 인의 유출부하 특성과 산화환원전위(Eh)의 변화 특성이 규명된다면, 향후 환경부하가 작은 물관리가 가능해 질 것으로 판단된다.

  • Das ursprngliche menshiche Verlangen nach Erotik hatte trotz der Unterdruckung und des Verbots seit der Anfang der Zeit bis heute stets das menschliche Interesse auf sich gezogen. Diese Erotik drckte nicht nur die knstlerische Handlung aus, sondern sie hat auch eine enge Beziehung zur kubischen Darstellung von Mode. Sie beschreibt die innere menschliche Welt und ist der Motor der individuellen Mode. Die Erotik entsteht wesentlich aus der Tiefe der menschlichen Psyche, ist sowohl erzeugende und starke schpferische Krfte als auch der Antrieb zur Annhrung der unsterblichen Welt. Darberhinaus ist sie auch der Wunsch jedes Individums, sich selbst zu entdecken. Diese Erotik beruht sich in unserem Unterbewutsein und Sie bricht nur dann aus, wenn der Mensch von der rtselhaften Leidenschaft beherrscht wird. Dardurch werden gewisse Krfte frei und sie motivieren den Menschen durch verschieden knstlerische Darstellung diese Erotik auszudrcken. Dieser ganz natrliche Ausdruck menschlicher Begierde wurde durch Kleidung nach Auen signalisiert. Damit drckte der Mensch seine Individualitt aus, und versuchte sich den anderen gegenber so reizvoll wie mglich zu zeigen und wirkte sehr anziehend. Schlilich hat er sich als Sex-Appeal zur Schau gestellt. Solches menschliche Sehnsucht nach Erotik wurde seit dem Altertum bis heute durch verschiedene erotische Kieidungen zum Ausdruck gerbracht.

  • FRBR family models, which is published from 1998 to 2010, will be restructured in 2016 and the new name of the model is "FRBR Library Reference Model (LRM)." FRBR LRM is a consolidated model based on the legacy FRBR family of conceptual models - FRBR, FRAD, FRSAD and the two ontological models - FRBRCore and FaBio, as well as FRBRoo, the cooperated model with museum field. In this study, therefore, FRBR LRM is analyzed in respect to background information, characteristics of the model, such as user tasks, entities, attributes, and relationships. Experimental adaptation to $prot{\acute{e}}g{\acute{e}}$ for the LRM's entities and relationships is also conducted. Through this test, the differences between the original models and the consolidated model was reviewed and the applicability of the FRBR LRM model to the semantic web is also discussed. From now on, we have to select and modify among the various FRBR related models to meet our information needs. It will be difficult to find only one Implementation Methodology for every information needs.

  • Compared to the past, the number of disabled people in Korea is continuing to increase. As for the scope of the disability, it is expanding as well since it now includes all types of illnesses, car accidents, complications resulting from aging, industrial accidents and others accidents. Attempts are made in terms of applying sports game method that grafts IT technology in order to ensure that the disabled people participate continually in sports. While casting away the notion of play which was the role of a game in the past, new roles and domains were developed. In fact, serious game genre is what leads this change. Because serious game is leading the game industry fast, centered on education, sports, fitness and medical use, its market value can be considered very significant since it can be both fund and effective as it targets the disabled who cannot enjoy sports easily in reality. Accordingly, this research seeks to present the direction for the application of serious game for the disabled people by analyzing the current situation pertaining to the integrated and converged cases applied to the field of sports for the disabled when it comes to the serious game that uses contents based on the IT technology.

  • This research is aiming to specify the requirement of the investment such as initial cost, running cost earning rate to make effective investment considering the purpose of remodeling and economical value of store building enough to meet the initial purpose of remodeling. The review of earning rate for economical evaluation was performed by the on-site auditing on the structure and function of the building and applying the assessment simulation program, which is to find the possible business model to identify the requirement of building owner through case study. After the research, the following results are obtained. First, it is important that many aspects should be carefully analysis and the best method should be selected as characteristics of remodeling can tie defer each other in their implementations. Second, though the remodeling of exist buildings to promote the functions has been applied. no suitable assessment tool has bee developed for deriding the level of remodeling in the view of economical efficiency so far. Third, the economical benefit was evaluated by analysing annual earning rate which is applied by investment items and recovery period for the investment. More specific data base should be established to apply the suggested economic accession in business enough to forecast the future circumstances. More researches should be promoted on this area continuously as well as the integrated economic evaluation of remodeling on existing building.

  • Total Project Cost Management System(TPCMS) was introduced with the purpose of increasing the efficiency of cost control for public construction project in 1994. In this paper, general perception of participants of the public construction project on the TPCMS was examined, and the problems in implementing the TPCMS was figured out through expert interviews and survey. Then better ways to implement the system were drawn based on the problems. To effectively manage the cost of public construction project, basically project cost should be estimated accurately in planning stage and managed based on it to have a project complete within the budget. In addition, the cost need to be managed in more systematic ways in terms of data collection and analysis, and the autonomy in managing the project cost given to the project owner needs to be expanded. Most of all, proper budget should be provided to prevent a project from delay through setting the priority of projects and proper budget allocation based on the priority.

  • New & renewable energy becomes a crucial subject to solve the problems inherent in the current energy resources, which results in the fast development of the new & renewable energy industry worldwide. However, not only its base is still weak but the high initial investment for technology development and certain scale of an energy market are required in many cases. For this reason, many countries in the world, including Korea, run the energy policies to foster the new & renewable energy industry such as RSP and FIT. In general, a policy should be established to take various, intertwined interests as well as a number of variables related to economic, social, environmental, and international matters into comprehensive consideration. For new & renewable energy industry, there are many variables to be considered and indexes necessary for evaluation but it is hard to take all of them into account. Even though they were considered, no criteria are available for use in a consistent manner. Therefore, this study plans to develop an evaluation model for the Korean new & renewable energy policy.

  • In this study, we investigated how a jumping strategy changes with an increase in the vertical jump height for a resultant ground reaction force (GRF) vector. We expected that the resultant force vector between two sequential motion phases (i.e., countermovement and push-off) of the countermovement jump would significantly change with the vertical jump height to take advantage of the resulting supportive force (i.e., an initial push-off force larger than the body weight) through the countermovement phase. Nine healthy young subjects were instructed to jump straight up to five different height levels ranging from 191 cm to 221 cm, and the kinematic and kinetic data were obtained in regular trials. The results showed that a lower center of mass position and larger resultant force vector were clearly observed in a higher jump, implying that the countermovement strategy changed with the vertical jump height to prepare for sufficient joint deviation and obtain a force advantage for larger push-off work.
