This study focuses on resetting the direction of the universities' accountability introducing the notion of accountability which is a new paradigm in the setting of records management.. First, we analyze the notion and structure of accountability, and then demonstrate the need of accountability in the university. And we try to deduce factors for accountability through cases of foreign universities. Based on this, we analyze the present status of records management of domestic universities. Based on the results of analysis, this study suggests several proposals. First, university records need to be reset. Second, regulations related to tasks in the university should be improved. Third, the function of university archives should be strengthened. Forth, the process of university records management should be reset. Fifth, in order to settle down accountability of the university in a right way, proper systems and procedures to regulate it are necessary so that the university can perform accountability properly outside the university.

The demand on applying the performance-based logistics (PBL) in the operational phase of the weapon systems development is increasing these days. Therefore, the enhancement of the PBL concept and process needs to be done. This is the objective of the paper. As a method of approach, a modeling method is adopted to cover the whole life cycle of the weapon systems development from the concept development to the operation. The modeling results for the PBL process yield an useful suggestion for improvement. Also, by analyzing the interrelationship model between the PBL process and the integrated logistics support (ILS) procedure, it is possible to take advantage of the PBL concept in the ILS elements development, which is usually carried out from the beginning of the development phase, a lot earlier than the operational phase. Note that the PBL concept has been restrictively applied in only the supply support among many ILS elements up until now. However, the results obtained in the paper can make it also possible to consider the availability, reliability, logistics support, cost and so on from the early phase of the weapon systems development.

Combustion Toxic Effects among several factors of risk encountered during fire are important in the evacuation and final survival, and they are broader and fatal than the direct damages caused by flame. Most studies on fire toxicity until the present are limited to fatality, mainly deaths by fire through pathological research. In this study, it is conducted as a fundamental experiment to address 3 principles of animal experiment and to provide an alternative test to animal testing that is regulated by national building codes and it was conducted through approval by the animal testing ethics committee. Hence, in this study average time of activity stop was measured after directly inhaling toxic gases (HCN) to laboratory animals (mice) through gas toxicity test (KS F 2271) for major asphyxiating gases(HCN) which are produced during fire combustion. effects of Combustion toxic gases on body were quantitatively analyzed through changes in internal organs and hematological analysis, and electrophoresis of a single cell of these laboratory animals. Biological conclusion of combustion toxicology is drawn through approaches (pathological examination, blood test, blood biochemical test, electrophoresis analysis of single cell) which could not confirmed in existing gas toxicity test.

The purpose of this study was to evaluate the dance attitude differences between gender, majors, and grades. Attitudes-towards-dance inventory(Jadranka et al., 2004) which covered affective, cognitive, and action aspects of attitudes, as well as to reflect, in a similar number of items, both the positive and negative attitude towards dance was used to investigate dance attitude for 483 dancers who are collegian. Male students were more positive attitude in the affective area among dance attitudes than female students(p<.05). Dancers who major practical dances revealed more positive attitude in the affective area than dancers majoring ballet and Korean treditional dance(p<.05). In addition, freshmen have a more positive dance attitude in the affective area compared with seniors. It was suggested that more subjects should be studied from considering major, local university as future study.

In this study, a new cleaning method using carbon dioxide pellet in the part of underground pipe cleaning method was proposed and verified. First of all, the commentary of The Society for Protective Coatings was examined in detail to determine the quantitative cleaning effects. Also, field tests were carried out to confirm the application of the new method. In the test, the surface condition of inner pipe after the application of the new method was investigated and two types of nozzles were compared in the tests. Also, the tests to measure the final impact pressure of air and carbon dioxide pellet mixtures were performed to investigate the losses of air pressure were investigated. Through this verification on the new method, it was found that the new method is very efficient for the removal of the rust in the pipe cleaning works. Also, the nozzle with excellent cleaning effect was also selected. As a result, this method will be able to largely contribute to the recycling of $CO_2$ which is limited to the use as a cooling agent or the storage of waste.

As the consumption of fishery products continues to increase, aquaculture industry has emerged instead of fishing industry facing limitations of fish stock resources. Recently, smart fish farming industry has rapidly developed through convergence with 4th Industrial Revolution technology. Accordingly, it is important to derive a future model of smart fish farming platforms in order to secure the superiority of the aquaculture industry and the technology standard hegemony. In this study, the future direction of smart fish farm platform was derived through the analysis of environment related to politics, economy, society, and technology related to smart fish farming by applying PEST methodology of macro-environment analysis. It is expected that it will help the public and industrial circles in planning and implementing related projects by including the entire process of value chain of aquaculture industry of breeding, production, management and distribution, and by presenting advanced models based on artificial intelligence and digital twin.

최근 3차원 반도체의 물질적인 한계를 극복하기 위해 2차원 전이금속 칼코게나이드(TMD)에 대한 연구가 활발히 진행되고 있다. 하지만 TMD 물질의 도핑 방법에 대한 수많은 연구에도 불구하고 대부분이 n채널 물질인 MoS2에 대한 것에 국한되어 있다. 게다가 이전의 TMD 도핑 기술 연구 결과는 채널이 도체화 될 정도의 매우 높은 농도의 도핑 현상만을 보여주었다. 이 연구에서 우리는 WSe2로 만든 p형 채널 트랜지스터에서 Octaecyltrichlorosilane(OTS)층의 농도 조절로 제어가 가능한 약한 농도의 p형 도핑기술을 보여준다. 이 p형 도핑 현상은 OTS의 메틸기(-CH3)그룹에 의한 양성 쌍극자모멘트가 WSe2내의 전자 농도를 낮추는데서 기인한다. 제어가 가능한 p형 도핑은 $2.1{\times}10^{11}cm^{-2}$ 사이에서 $5.2{\times}10^{11}cm^{-2}$로 degenerate되지 않은 정도로 WSe2 기반의 광, 전기적인 소자에서 적절한 농도로 최적화 될 수 있다. (도핑 정도에 따른 문턱전압 상승, 전류 on/off율 상승, 전계효과 이동도 상승, 광응답성 하락, 광검출성 하락) 또한 OTS에서 비롯한 p도핑 효과는 대기중에서 오랜시간이 지나도 작은 성능 변화만을 보여주며(60시간 후 18~34% 문턱전압 감소변화량) $120^{\circ}C$의 열처리를 통하여 저하된 성능이 거의 완벽하게 회복된다. 이 연구는 Raman 분광법과 전기적, 광학적 측정을 통하여 분석되었으며 OTS 도핑현상이 WSe2 박막의 두께와 무관함 또한 확인했다.

Although the strengthening effect of deteriorated concrete bridge decks has been studied by various authors, most researches are focused on the experimental works on the pulsating loading in laboratory in spite of deterioration of deck caused by moving vehicle loads. In this research, a theoretical live load model that was proposed to reflect an effect of moving vehicle loads is formulated from a statistical approach on the measurement of real traffic loads for various time periodsin Korea. Fatigue life and strengthening effect of strengthened bridge decks strengthened with either Carbon Fiber Sheet or Grid typed Carbon Fiber Polymer Plastic by the probabilistic and the reliability analyses are assessed. As a results, secondary bridge deck (DB18) strengthened with FRP ensures a sufficient fatigue resistance against the increased traffic loads as well as load carrying capacity in life cycle.

A variety of wireless devices are commercially available now. Most of studies, however, have been directed to the biological effects of mobile-phone EMF. In this paper, dosimetric analysis for wireless devices of head-mounted display type and a wristwatch type were made to investigate possible biological effects of these devices. SAR(Specific Absorption Rate) distributions were calculated using FDTD(Finite Difference Time Domain) method, for adult human models such as standard Korean human model and VHP(Visible Human Project) model, as well as scaled child models. Measurements were also performed for SAM phantom wearing a simplified prototype for a wireless device for validation of the simulation results. It has been found that children are more vulnerable to such exposure, and these devices could cause some biological effects even for relatively lower power compared to conventional mobile pones.
