Purpose: The purpose of this study was to explore preceptees' experience among nursing students in the Clinical Nursing Practice program as integral practice. Specific aims were to identify problems students face as preceptees at a clinical practice and how they interact with preceptors and others. Methods: Grounded theory methodology was utilized. Data were collected from interactive field notes and transcribed notes with individual in-depth interview from 12 senior nursing students who had experiences as a preceptee in the Clinical Nursing Practice. Results: Through constant comparative analysis, a core category emerged as "Being refined while taking a firm stand with lack." The process of "Being refined while taking a firm stand with lack" consisted of four phases: sailing phase, adaptation phase, achievement phase and wistful returning phase. Conclusion: The findings of the study indicate that there is a need for nursing students to understand the limitations and strengths to learning experiences in preceptorship. In addition, the Clinical Nursing Practice as an integral practice program is needed to improve nursing capacity and for proper adaptation to real clinical environment among graduating students.

The block-unit housing renewal project was presented as an alternative method to overcome the side effects of large-scale renewal projects while improving poor residential conditions. However, projects implementation is prolonged and even the pace of projects, which was considered an various incentives, is being delayed for the most part. In this study, delay factors are drawn by eight; conflict among association members, contract delay of joint implementation, participation paucity of constructor, inadequate project guidelines, alteration of project plan, lack of renewal project professionals, stricter loan restriction of HUG, lack of capacity of project operator. We categorized those eight factors to three aspects such as implementation, participants and proposition and suggested improvement alternatives according to three aspects.

As metropolitan areas are rapidly growing in both population and physical size, so too has the problem of traffic congestion. Magnifying this is the limited financial resources and lack of road corridor space available to juggle the many competing demands. High Occupancy Vehicle (HOV) facilities have been implemented in an attempt to alleviate the problem of growing congestion while considering the issue of limited funding and lack of physical space. HOV lanes may increase the efficiency of a road corridor by maximising its person carrying capacity. These facilities are meant to provide priority treatment to HOVs, thereby luring people to choose a transport mode with a higher occupancy than the single occupant vehicle (SOV), such as buses or carpools. This paper analyze the issues surrounding HOV lanes, their effect, problems and their evaluation by using Intergration, that is Traffic Simulation Software, when HOV lanes be implemented in the Olympic Highway.

This study applied elastic supports in order to evaluate load carrying capacity using measurement data obtained from load tests actively and utilizing various evaluation methods. In order to confirm the adequacy of structural analysis based on elastic supports and to improve the reliability of experiment results, we conducted a deflection test with flexural beams prepared as overhanging beams and, based on the results, performed precision safety diagnosis for real bridges under public service for improving the load carrying capacity evaluation method for bridges under public service. In the results of the bending test, compared to deflection calculated by the existing method, deflection obtained by applying elastic supports was closer to the actually measured deflection. In the results of evaluating load carrying capacity for a 3 span continuous steel box girder bridge just after its completion, load carrying capacity by elastic supports was smaller by up to 39% than that by the existing method. When the load carrying capacity of bridges is evaluated by the existing method the results vary among engineers due to lack of guidelines for evaluation such as the application of stress modification factor. This study was conducted as an effort to solve this problem through active research.

Purpose: Although the number of cancer survivors is increasing because of early diagnosis and better treatment, they are worried about relapses and metastasis. This study examined the dietary safety management awareness, capacity, and behavior of cancer survivors. Methods: Data were collected from 233 cancer survivors in Daegu and Gyeongbuk areas using a self-administered 5-Likert questionnaire from March to May 2018. Frequency analysis, one-way analysis of variance, factor analysis, reliability analysis, and correlation analysis were analyzed using the SPSS. Results: The average score for each factor was as follows: importance of weight management (3.83), education requirement (3.79), unhealthy diet (reverse, 3.64), food safety anxiety (3.34), lack of awareness of over and malnutrition (reverse, 3.26), obsession (3.23), cooking capacity (3.16), health-function pursuit (3.04), balanced diet (2.93), and chronic disease anxiety (2.64). The average dietary safety competency factors were significantly lower among the male survivors, aged 60-80 years, lower economic condition, and less nutritional supplement intake. Female survivors comprised the highest proportion with high health management and cooking capacity, while men had the lowest of all the factors (p < 0.001). The group that was low in all three capacity factors had a significantly lower average score of difficulty in acquiring knowledge (reverse), lack of awareness of over- and malnutrition (reverse), importance of weight management, education requirement, knowledge, balanced diet, and health-functional pursuit compared to the other groups (p < 0.001). Conclusion: To effectively manage health, dietary safety management education should be differentiated and actively conducted according to sex, age, cancer diagnosis time, economic status, nutritional supplement intake, and the capacity cluster of cancer survivors.

The numbers of occurrences and the amount of spills of marine oil pollution have increased, and accordingly, it is necessary to secure additional control capabilities. Therefore, it was intended to present an empirical basis for improving the overall idle capacity through the relocation of control ships existing in each region. First, the marine pollution index was derived and the control capability compared to the marine pollution index of each region was compared to examine the appropriateness of the deployment of control ships. The marine oil pollution risk index was derived by multiplying the nine items that cause marine pollution by the weight derived by experts. We checked the control capacity (A) compared to the marine pollution risk index (F) for each sea area. Mokpo (F:13.4, A:1.9), Busan (F:14.3, A:6.4), and Yeosu (F:21.5, A:16.6) are the areas that lack control capabilities compared to the marine pollution risk index. On the other hand, the areas that have room for control compared to the marine pollution risk index for each sea area are Masan (F: 5.9, A:13.3), Gunsan (F:1.7, A:8.3), and Jeju (F:2.7, A:6.9). Therefore, for improving the standardized control capacity proportional to the risk of marine pollution nationwide, it is suggested that the control ships of Masan, Gunsan, and Jeju should be relocated to Mokpo, Busan, and Yeosu, which lack control capacity.

To cope with increasing power demand in metropolitan area, the power system in Korea has equipped with unit generator of large capacity, high density and uneven distribution, and transmission line of long distance, large capacity and high voltage. As the power system growing up enormous, it has become difficult to maintain the standard voltage in case of radical fluctuation of load or severe change of voltage by power system fault for its weakness of responsive characteristics although the power condenser has been installed to solve the unstability by lack of reactive power. Consequently, we review harmonic wave production and control characteristics to solve unstability problem of voltage in northern metropolitan, to reduce transmission restriction cost and to minimize load shedding by relocation of SVC (Static Var Compensator), which is highly effective for improvement of responsive characteristics for radical voltage fluctuation.

Large dams are managed with operation standard and flood forecasting systems, while small dams do not have management method generally. Shortage of water resources and natural disasters due to drought and flood raised public concerns for management of small dams. Most of small dams are irrigation dams, which need diversified water uses. However, the lack of systematic management of small dams have caused serious water wastage and increased natural disasters. Storage management method and system were developed to solve these problems in small dams. The system was applied to Seongju dam for effective management. The storage management method was established considering hydrology simulation and statistical analysis using the system. This method can bring additional available water, even in the same conditions of the water demand and the supply conditions of watershed. It can improve the flood control capacity and water utilization efficiency by' the flexible operation of storage space.

This paper presents The performance analysis of inverter control type-industrial cooler with respect to refrigeration load and outdoor temperature. Aside from materials about simulations and foundation data regarding inverter control compressors, currently, data about commercial coolers with inverter control still lack information for performance comparison. Thus, in this paper, the experiments are done to see characteristics of condensation capacity, evaporation capacity, compressor power and COP with respect to outdoor temperature and load by using a commercial inverter control cooler model. As a result, COP difference of the inverter control cooler with respect to load is 30% at the outdoor temperature of $35^{\circ}C$, 29% at the outdoor temperature of $30^{\circ}C$, 34% at $25^{\circ}C$, respectively.
