그동안 극예술연구회의 제10회 공연작에 대한 연구는 거의 시행되지 않았다. 특히 이서향의 <어머니>는 거의 연구되지 않았으며, 기껏해야 제10회 공연작 중 하나였다는 사실 정도만 기록되곤 했다. <어머니>의 희곡이 남아 있고, 제10회 공연이 상당한 의의를 지닌 정기공연이었음에도 불구하고, 이러한 연구 실태는 대단히 열악한 것이 아닐 수 없다. 그것은 단막극 <어머니>가 드러내는 공연사적 가치와 의미를 정밀하게 고찰하지 못한 결과로 보인다. 이러한 문제를 극복하기 위해서는 <어머니>의 공연 정황을 살펴보고, 당시 극예술연구회의 상황을 조사할 필요가 있다. 그리고 <어머니>의 선정 이유, 실제 무대 공연 현황, 연극적 요소, 무대 디자인, 관련 평가를 두루 살펴보아야 한다. 이 연구는 이러한 <어머니>의 공연 정황을 점검하고 그 의의를 살피는 데에 초점을 두었으며, 그 결과를 통해 극예술연구회의 한 맥락으로서 여성 연극의 흐름에 대해 논구하고자 한다.

The purpose of this longitudinal case study is to shed light on the reliability problems of IS performance evaluation by analyzing the discrepancy between ex ante evaluation in 2011 and ex post evaluation in 2012. Through an information system development project of a public enterprise, the gap between ex ante and ex post evaluation was ascertained and the causes as to why such gap occurs and the success factors that can solve the problems were derived. The ex ante evaluation of IS performance was performed based on both IS success model and BSC model and the ex post evaluation was carried out at the time after the target system has been built up by applying the evaluation measures and process that are similar to the ex ante evaluation. In the ex ante evaluation the business performance improved by the target system was estimated to 18.2%. On the other hand, it was seen as being low at 15.2% in the ex post evaluation and the differences were found to be statistically significant in 6 out of 10 measures. The reasons as to why such gap occurs were diagnosed as being of 2 types : (1) changes in the evaluation psychology according to the differences in the evaluation objectives; and (2) excessive expectation levels of the target system that is formed at the time of the ex ante evaluation. In other words, the users who have excessive expectations tend to overestimate in the ex ante evaluation and, in the ex post evaluation, tend to underestimate lower than the actual performance mainly due to disappointment on the results that do not meet the early expectations. As solutions to overcome the reliability problem of ex ante evaluation, 3 factors were derived : (1) the temperance of excessive expectation levels of the users; (2) a clear definition of the scope and functionality of the target system; and (3) actual commitments for the evaluations of IT performance.

Depression is one of the most common psychologic disorder and dealt as a major public health concern. School students have heavy school work loads and stress from various evaluations representing school performance. In this study, to examine the effect of school performance and stress on depressive symptoms, we assessed the frequency of risk factors for depressive symptoms among 2,717 high school students. From April 2001 to May 2001, using a self-reported questionnaire, we collected data on the frequency of occurrence of depressive symptoms and potential risk factors for depressive symptoms. Depressive symptoms were measured using Center Epidemiologlc Studies Depression (DES-D) index. Thirty-seven percent of high school students reported having high depressive symptoms for a week Female students had a higher prevalence of depressive symptoms than males (OR=1.44, 95% CI 1.22-1.70). In a multiple logistic regression model, we found that good perceived school performance (OR=0.43, 95% CI 0.31-0.60) had a negative association with depressive symptoms. On the contrary, we also found that stress from school performance (OR=2.03, 95% CI 1.69-2.44) associated with high depressive symptoms. In conclusion, high school students had a relatively high prevalence of depressive symptoms. Students with stress from school performance had the higher risk for depressive symptoms.

Purpose: Some of the most representative approaches are to apply next generation technologies to save energy consumption, fully automated control system to appropriately maintain environmental conditions, and autonomous assistance system to reduce labor load and ensure operator's safety. Nevertheless, improvement of upcoming method for soil cultured greenhouse has not been sufficiently achieved. Geometrical complexity of ground in protected crop cultivation might be one of the most dominant factors in design of autonomous vehicle. While there is a practical solution fairly enough to promise an accurate travelling, such as autonomous sprayer guided by rail or induction coil, for various reasons including the limitation of producer's budget, the previously developed sprayer has not been widely distributed to market. Methods: In this study, we developed an autonomous sprayer considering travelling performance on geometrical complexity of ground in soil cultured greenhouse. To maintain a stable travelling and to acquire a real time feedback, common wire with 80 mm thick and body frame and sprayer boom. To evaluate performance of the prototype, tracking performance, climbing performance and spraying boom's uniform leveling performance were individually evaluated by corresponding experimental tests. Results: The autonomous guidance system was proved to be sufficiently suitable for accurate linear traveling with RMS as lower than approximately 10 cm from designated path. Also the prototype could climb $10^{\circ}$ of ground's slope angle with 40 kg of water weight. Uniform leveling of spraying boom was successfully performed within $0.5^{\circ}$ of sprayer boom's slope. Conclusions: Considering more complex pathways and coarse ground conditions, evaluations and improvements of the prototype should be performed for promising reliability to commercialization.

PURPOSES: The liquid-type chemical warm-mix asphalt (WMA) additive has been developed. This study evaluates the basic properties of the additive and the mechanical properties of WMA asphalt and mixture manufactured by using the newly developed chemical additive. METHODS: First, the newly developed WMA additive was applied to the original asphalt by various composition of additive components and dosage ratio of additive. These WMA asphalt binders were evaluated in terms of penetration, softening point, rotational viscosity, and PG grade. Based on the binder test results, one best candidate was chosen to apply to the mixture and then the mechanical properties of WMA mixture were evaluated for moisture susceptibility, dynamic modulus, and rutting and fatigue resistance. RESULTS : According to the binder test, WMA asphalt binders showed the similar properties to the original asphalt binder except the penetraion index of WMA additive was a little higher than original binder. From the Superpave mix design, the optimum asphalt content and volumetric properties of WMA mixture were almost the same with those of hot mix asphalt (HMA) mixture even though the production and compaction temperatures were $30^{\circ}C$ lower for the WMA mixture. From the first set of performance evaluation, it was found that the WMA mixture would have some problem in moisture susceptibility. The additive was modified to improve the resistance to moisture and the second set of performance evaluation showed that the WMA mixture with modified chemical additive would have the similar performance to HMA mixture. CONCLUSIONS : Based on the various laboratory tests, it was concluded that the newly developed chemical WMA additve could be successfully used to produce the WMA mixture with the comparable performance to the HMA mixture. These laboratory evaluations should be confirmed by applying this additive to the field and monitoring the long-term performance of the pavement, which are scheduled in the near future.

The sodium-cooled fast reactor is among the innovative nuclear technologies selected in the framework of the development of Generation IV concepts, allowing the irradiation of uranium-plutonium mixed oxide fuels (MOX). A fundamental step for the safety assessment of MOX-fuelled pins for fast reactor applications is the evaluation, by means of fuel performance codes, of the integral thermal-mechanical behaviour under irradiation, involving the fission gas behaviour and release in the fuel-cladding gap. This work is dedicated to the performance analysis of an inner-core fuel pin representative of the ASTRID sodium-cooled concept design, selected as case study for the benchmark between the GERMINAL and TRANSURANUS fuel performance codes. The focus is on fission gas-related mechanisms and integral outcomes as predicted by means of the SCIANTIX module (allowing the physics-based treatment of inert gas behaviour and release) coupled to both fuel performance codes. The benchmark activity involves the application of both GERMINAL and TRANSURANUS in their "pre-INSPYRE" versions, i.e., adopting the state-of-the-art recommended correlations available in the codes, compared with the "post-INSPYRE" code results, obtained by implementing novel models for MOX fuel properties and phenomena (SCIANTIX included) developed in the framework of the INSPYRE H2020 Project. The SCIANTIX modelling includes the consideration of burst releases of the fission gas stored at the grain boundaries occurring during power transients of shutdown and start-up, whose effect on a fast reactor fuel concept is analysed. A clear need to further extend and validate the SCIANTIX module for application to fast reactor MOX emerges from this work; nevertheless, the GERMINAL-TRANSURANUS benchmark on the ASTRID case study highlights the achieved code capabilities for fast reactor conditions and paves the way towards the proper application of fuel performance codes to safety evaluations on Generation IV reactor concepts.
