국내 주택건설시장은 가격 경쟁의 심화와 함께 형태 구조적인 다양화가 동반되어 사업의 불확실성이 증가하고 있다. 이로 인해 건설사업 기획단계의 중요성이 강조되고 있으며, 점점 더 높은 정확도를 가진 개산견적을 요구하고 있다. 현재 초기 기획단계의 공사비 산정에 관한 연구나 프로그램 개발이 다수 이루어지고 있으나, 지역성을 고려하여 결과를 도출한 경우는 많지 않다. 비용 산정 시 지역적 보정이 함께 이루어진다면 보다 정확한 비용 추정이 가능하고, 이는 곧 성공적인 프로젝트 수행에 큰 역할을 할 수 있을 것이다. 따라서 본 연구의 목적은 공공아파트 실적데이터를 기반으로 하여 지역지수 산정 방법론 및 산정 모델을 구축하고, 공사비 추정 시 활용할 수 있는 지역지수를 도출하는 것이다.

Since 1982, the government of Korea has actively promoted vertical cooperative R&D programs between government-sponsored research institutes (GRIs) and private firms. A number of firms participated in the programs because cooperative R&D could lower the risk and could contribute to rapid commercialization of many technologies. This paper examines the effectiveness of vertical cooperative R&D projects by the modes of cooperation between GRIs and industrial firms, and analyzes the performance of participating firms' technology sourcing strategies for commercial utilization of cooperative R&D results at the project performed from 1982 to 1989 under the Government-Industry Cooperative R&D Program sponsored by the Ministry of Science and Technology(MOST) in Korea. The cooperative R&D projects are classified into 4 groups by two criteria, i.e., the level of participation of firms, and the breadth of cooperation. The findings suggest that firms should actively participate in cooperative R&D projects. In addition, in order to enhance commercial success, cooperation between GRIs and industrial firms should not be limited to R&D stage only. The breadth of cooperation should be extended to commercialization stage. Small- and medium-sized firms participating in vertical cooperative R&D projects in Korea usually lack internal technological capabilities that are needed to commercialize the results of cooperative R&D. Three different technology sourcing strategies - exclusive cooperative R&D strategy, in-house development augmented cooperative R&D strategy, and licensing-in supplemented cooperative R&D strategy - are empirically derived through cluster analysis of the relative usage rates cooperative R&D and of other supplementary technology acquisition methods. The findings suggest that the firms participating in vertical cooperative R&D projects should try to utilize other supplementary technology acquisition methods in order to achieve commercial utilization of the vertical cooperative R&D results.

This study investigates the potential components for academic research collaboration, and the factors that make it possible to achieve higher academic productivity. The components include collaboration factors and a collaboration model. We use two major collaboration factors to develop a framework for understanding the mechanisms that influence academic research collaborations: motivational factors and mediating factors. Motivational factors include self-motivation and trust whereas mediating factors are collaboration orientation and peer support. We analyze the effect for use of e-collaboration with research performance, reward, and satisfaction with e-research output. A survey of academicians was conducted, and by using the factor analysis and the structural equation model with SPSS 20 AMOS, we illustrate the possible influence of these factors on research performance and satisfaction. We discovered that both motivational and mediating factors play important roles on the success of academic research. This study offers several implications for academicians. We develop a parsimonious research model, which is related to e-collaboration in academic research. This unique model offers academicians to achieve good publication output from the research team. The motivational factor, self-motivation and trust, are important factors which has received positive impact of mediating factor collaboration orientation and peer support. Our research sheds light on the crucial factors for use of e-collaboration which offer the ultimate effect on performance and satisfaction with e-research output. Satisfaction motivates people to work more and more on the field of their interest, thereby influencing the performance of academicians. Rewards should be distributed according to performance of the individual, which will motivate the person to become more enthusiastic for his work of interest. Our evidence suggests that in understating the collaborative process, one must account for the context in which the collaboration occurs, the motivation of the collaborators, the scope and nature of the project, the roles and activities undertaken, and interpersonal processes such as trust. Researchers' motivations for engaging in collaboration were both instrumental and intrinsic.

Purpose: Magnetic resonance imaging (MRI) is a useful tool for evaluating brain injury and maturation in preterm infants and often requires sedation to acquire images of sufficient quality. Infant sedation is often associated with adverse events, despite extreme precautions. In this study, the swaddling technique was investigated as an alternative non-pharmacological strategy to obtain brain MRIs of sufficient quality. Methods: We applied the feed and swaddle technique during routine brain MRI as a quality improvement project and compared its morbidity with that of sedation in a historic age-matched group. Seventy-nine very low birth weight infants in the neonatal intensive care unit of Ajou University Hospital (Suwon, Korea) were enrolled. Thirty-two (40.5%) infants were in the feed and swaddling group, and 47 (59.5%) were in the sedation group. Results: The morbidity associated with the cardiopulmonary system (swaddling group vs. sedation group: 53.13% [n=17] vs. 63.83% [n=30], P=0.723) and central nervous system (40.63% [n=13] vs. 29.79% [n=14], P=0.217) were not significantly different between groups. The MRI failure rate was not significantly different (swaddling group vs. sedation group: 12.5% [n=4] vs. 4.3% [n=2], P=0.174). The MRI scanning time was longer in the swaddling group than in the sedation group (76.5±20.3 minutes vs. 61.5±13.6 minutes, P=0.001). Cardiopulmonary adverse events were significantly less common in the swaddling group than in the sedation group (3.13% [n=1] vs. 34.04% [n=16], P=0.002). Conclusion: The success rate of MRI was comparable between the swaddling technique and sedation. Furthermore, despite the drawback of prolonged scan time, cardiopulmonary adverse events are fewer with swaddling than with sedative agents. Therefore, swaddling can be an alternative to sedation or anesthesia when performing neonatal MRI scans.

As many critics do, this article starts from the premise that Charles Waddell Chesnutt wrote The Conjure Woman with a distinct socio-ethical view to ameliorating white readers' racism. For this purpose of social activism, first, the author uses a racially submissive genre and narrator- antebellum plantation-dialect fiction and an old ex-slave Julius-in order to win the attention of white racists, who constituted the majority of the reading public of postbellum America. Chesnutt then allows this seemingly submissive ex-slave consecutively to wage narrative battles against a Northern white capitalist, John. This fiction's structure is thus based on interracial narrative conflict. Granted, the result of these narrative battles is Julius's defeat. Even though he sometimes has narrative success through his manipulation of either his white female auditor's sentimentalism or the white capitalist's racial prejudice, it does not lead to any fundamental change in the white audience members' awareness: John still regards Julius's tacitly reformoriented tales merely as nonsensical ghost stories invented by the absurd imagination of a subservient, entertaining, and exploitable black coachman. Admitting his defeat, Julius relinquishes his original goal of deterring John's capitalist exploitation of both racial Others and the natural environment of the South and finally decides to serve the economic power of white capitalism. This self-defeating conclusion, however, should not be identified with Chesnutt's failure as an author. Rather, it should be understood as an interim result of the black author's earnest experiment with literary media best suited to his reform project. In fact, this narrative failure reveals Chesnutt's accurate diagnosis of the postbellum literary world: a black voice is still feebly heard and even easily buried by the whites' capitalist ambition and consequently intensifying racism. Conclusively, Julius's narrative failure should be positively evaluated as Chesnutt's one step further in his gradual and lifelong progress to a narrative goopher effectively to engage whites' imagination and sympathy for a vision of equal interracial coexistence.

In the core of the WWR-K reactor, a long-term irradiation of tristructural isotopic (TRISO)-coated fuel particles (CFPs) with a UO₂ kernel was carried out under high-temperature gas-cooled reactor (HTGR)-like operating conditions. The temperature of this TRISO fuel during irradiation varied in the range of 950-1100 ℃. A fission per initial metal atom (FIMA) of uranium burnup of 9.9% was reached. The release of gaseous fission products was measured in-pile. The release-to-birth ratio (R/B) for the fission product isotopes was calculated. Aspects of fuel safety while achieving deep fuel burnup are important and relevant, including maintaining the integrity of the fuel coatings. The main mechanisms of fuel failure are kernel migration, silicon carbide corrosion by palladium, and gas pressure increase inside the CFP. The formation of gaseous fission products and carbon monoxide leads to an increase in the internal pressure in the CFP, which is a dominant failure mechanism of the coatings under this level of burnup. Irradiated fuel compacts were subjected to electric dissociation to isolate the CFPs from the fuel compacts. In addition, nondestructive methods, such as X-ray radiography and gamma spectrometry, were used. The predicted R/B ratio was evaluated using the fission gas release model developed in the high-temperature test reactor (HTTR) project. In the model, both the through-coatings of failed CFPs and as-fabricated uranium contamination were assumed to be sources of the fission gas. The obtained R/B ratio for gaseous fission products allows the finalization and validation of the model for the release of fission products from the CFPs and fuel compacts. The success of the integrity of TRISO fuel irradiated at approximately 9.9% FIMA was demonstrated. A low fuel failure fraction and R/B ratios indicated good performance and reliability of the studied TRISO fuel.

This study is conducted to provide an empirical review on how schools play a pivotal role in the regional communities. For this, the use of closed schools, activities to revive small-scale schools, and activities related to nearby schools outside the village were analyzed for villages that have participated and have been awarded in the Contest for Making Happy Rural Communities by the Ministry of Agriculture, Food and Rural Affairs. The results of this are as follows. Out of 204 villages that won the contest, there were 19 cases of school closures. Of these 19 cases, there are 17 cases in which the closed school facilities still exist. For the two remaining cases, there are no buildings and only the site remains. To summarize the use of these schools, the functions are being combined and are determined within the range that local residents can operate. The impact or success factors on the region can be summarized into five main categories through the revival of schools in the crisis of closure. First, it was an opportunity to lay an organizational foundation for village projects in the future by reorganizing the village's organization, such as the formation of a village promotion committee to revive the schools. Second, it did not just introduce outsiders to increase the population, but supported housing and jobs for them to successfully settle down. Third, a cultural community was created with senior and junior residents, and finally, the residents became teachers or formed a village education communities such as lifelong education. In the relationship with schools existing outside the village, activities with members of the surrounding schools and linked activities are being carried out in the sense of "school".
