  • This paper reports a comparative review of the service quality attributes of Electronic Customs Clearance (UNI-PASS) by applying the Kano model, Timko's BW coefficients, and IGA model, as reported by Tontini et al. in terms of a service quality evaluation of electronic customs clearance as the comprehensive national customs administration information system. In addition, this study examined which quality attributes should be focused on to improve the service quality and enhance customer satisfaction using the electronic customs clearance service. The Kano, Timko, and IGA models were classified into the four common quality attributes: attractive quality, one-dimensional quality, must-be quality, and indifferent quality. Because the integrated approach was used, one-dimensional quality was included in the area for critical improvement, while the must-be quality was included in the area for intensive maintenance. In addition, the indifferent quality was included in the area of carefree, while the attractive quality was included in the area of competitive advantage.

  • 본 연구에서는 소유역에서 발생하는 오염물질의 정량화를 위해 오염원 그룹별 발생부하와 배출부하를 분석하고자 하였다. 대상유역은 경기도 가평군 일대이며, 소유역을 8개의 세유역으로 구분하여 발생부하와 배출부하를 산정하였다. 오염원 현황자료는 2012년 전국오염원 조사자료를 기초로 하였으며, 행정구역 단위의 오염원 조사 및 행정구역과 유역의 경계가 일치 하지 않는 경우의 오염원별 점유율은 토지종합정보망(Land Management Information System, LMIS)의 연속지적도 자료를 이용하여 면적비로 산정하였다. 또한 발생원 단위는 실측자료를 우선으로 하되 실측자료가 없는 경우 수질오염총량관리기술지침에서 제시하는 발생원단위를 적용하였다. 대상유역 내에는 산업계, 양식계, 매립계의 오염원은 없었으며, 생활계와 축산계, 토지계 중 축산계의 발생부하량이 BOD, T-N, T-P 모두 가장 높은 것으로 분석되었다. 대상유역의 BOD 발생부하량은 총 891.51kg/day로 산정되었으며, 이 중 축산계가 포함되어 있는 유역의 BOD 발생부하량이 전체의 76.4%에 해당하는 680.70kg/day로 가장 높게 나타났다. 반면, 배출부하량은 생활계, 축산계, 토지계 중 BOD와 T-N은 토지계 배출부하량이 차지하는 비율이 가장 높았으며, T-P의 경우 축산계의 발생부하량이 가장 높은 것으로 나타났다. 유역의 BOD 배출부하량은 총 89.84kg/day로 산정되었으며, 이중 유역 하류에 위치하고 있는 세부 소유역의 BOD 배출부하량이 전체의 30.5%에 해당하는 27.4kg/day로 가장 높게 나타났다. 그러나 총 T-P 발생부하량은 14.12kg/day로 산정되었으며, 축산계가 포함되어 있는 소유역의 T-P 발생부하량은 전체의 64.3%에 해당하는 9.08kg/day로 가장 높았다. 이는 대상유역 내 축산농가의 분뇨가 위탁 처리됨에 따라 발생 부하량에 비해 배출부하량은 상당량 감소하는 것으로 분석되었다. 특히, BOD와 T-N의 경우 축산농가의 영향이 적었지만, T-P의 경우 자연농도가 낮기 때문에 축산농가의 배출부하량이 높은 비중을 차지하는 것으로 판단된다. 그러나 오염원의 정량적인 발생원 규명을 위해서는 오염원 그룹이 포함되어있는 지역에 대하여 장기적인 실측 모니터링 결과를 바탕으로 오염부하를 산정하여 비교?분석하는 연구가 필요할 것으로 판단된다.

  • Economic analysis predicts that the drone market will grow, and the growth of the toy and hobby drone market is expected to gradually expand. Drone expectations are rising due to the net economic function of drone market growth, but accidents due to improper management and operations are also increasing. The difference in toy drone performance is incomparably small compared to industrial drone performance, but the ordinary buyer can not know whether the difference can cause an accident during use. The toy drones used in this study were obtained from KC and CE certification, and 20 kinds of drones were used. The flight time ranged from a minimum of 3 minutes to a maximum of 12 minutes, and the control distance ranged from a minimum of 20m to a maximum of 380m. Therefore, it is necessary to secure product safety through sampling inspection of the radio wave output of toy drones, and it is also necessary to mount an algorithm that automatically lowers the altitude or hover when exceeding the limit flight distance. For future research, we will build data to establish toy drone safety standards through a altitude testing and impact testing of toy drone.

  • This study was conducted to empirically analyze the prevalence and risk of chronic diseases in the family history of chronic diseases using data from the Korea National Health and Nutrition Examination Survey 2019. Based on 5,691 people, after controlling for socio-demographic variables that were related to family history of chronic diseases, logistic regression analysis was performed to verify the odds ratio, which was the risk of family history of chronic diseases for the prevalence of chronic diseases. The main results were founded that Odds ratio, which was the risk of chronic diseases in groups with a family history compared to those without a family history, was statistically significant at hypertension(2.623), dyslipidemia(1.868), diabetes(1.964), and arthritis(1.435) when gender, age, income status, education level and residence were controlled. These results suggest that it is not only necessary to develop a standardization tool for family history tests, but also a health and disease management system for members with a family history in terms of preventive medicine in health care. This study is significant in that it proposed a practical plan in terms of health care by controlling variables that affect the prevalence of chronic diseases and empirically identifying the risk of family history of chronic diseases.

  • A fixed reflectivity-rainfall relationship approach, such as the Marshall-Palmer relationship, for an entire year and different seasons, can be problematic in cases where the relationship varies spatially and temporally throughout a region. From this perspective, this study explores the use of long-term radar reflectivity for South Korea to obtain a nationwide calibrated Z-R relationship and the associated uncertainties within a Bayesian inference framework. A calibrated spatially structured pattern in the parameters exists, particularly for the wet season and parameter for the dry season. A pronounced region of high values during the wet and dry seasons may be partially associated with storm movements in that season. Overall, the radar rainfall fields based on the proposed modeling procedure are similar to the observed rainfall fields. In contrast, the radar rainfall fields obtained from the existing Marshall-Palmer relationship show a systematic underestimation. In the event of high impact weather, it is expected that the value of national radar resources can be improved by establishing an active watershed-level hydrological analysis system.

  • Related to the previous paper on the typical crack pattern of tunnel lining with NATM, the characteristic defects in reinforced cement concrete lining of NATM tunnel have analyzed with the precise inspection with safety and diagnosis (PISD) by KISTEC. Depending on the reinforcing materials, steel rebar, steel fiber, and glass fiber have been implemented to reinforcing lining in various NATM tunnel constructions. Reinforcing lining with rebar are prevailed on NATM tunnel to countermeasure the weak geological circumstances, to pursuit the economical tunnel sections, and to resist the risk of tunnel deterioration. By the special act on the safety control of public facilities, the reinforced NATM tunnels for more than 1 km length are scrutinized closely to characterize defects; crack, reinforcement exposure, and lack of lining. Crack resistance by reinforcing is shown in comparison with the normalized crack to the length of tunnel. Typical exposed reinforcements in lining have exemplified with various sections. The lack of lining due to the mal-construction, spalling, fire, earthquake and leaching has been analyzed. The cause and mechanism with the field inspections and other studies has also been verified. Detailed cases are selected by the above concerns as well as the basic information from FMS (Facilities Management System). Likewise the previous paper, this study provides specialized defects in reinforced lining of NATM and it can be widely used in spreading the essential technics and reporting skills. Furthermore, it would be advised and amended for the detail guideline of Safety Diagnosis and PISD (tunnel).
