In order to assess the relative importance of providing rural life services for the sustainability of rural communities and determine their prioritization, this study employed Analytic Hierarchy Process (AHP) to derive the relative importance of sectors and items in the realm of life services influencing the quality of rural life. A survey was conducted with three groups of experts. Group I consisted of experts in rural life services and rural environmental research (22 individuals), Group II included government officials responsible for implementing rural agreements in pilot areas (18 individuals), and Group III comprised executives from the Rural Life Improvement Association and 4-H organization working towards improving rural life and society (20 individuals). The analysis results revealed the following facilities as top priority in their respective categories: ‘National and Public Childcare Centers’ for ‘Childcare,’ Elementary and Middle Schools for ‘Education,’ Senior Welfare Facilities for ‘Welfare,’ Cultural Centers and Local Cultural Facilities for ‘Culture,’ Public Sports Facilities for ‘Sports,’ Emergency Medical Services for ‘Healthcare,’ Commercial Facilities in daily routines for ‘Commercial and Residential Services,’ Emergency Safety Agencies for ‘Administration and Security,’ and rural village Shelter for ‘Leisure and Rest.'

PURPOSES : This study aims to examine actual cases of providing detour information in accidental situations such as traffic accidents and road construction through a VMS installed on national highways in metropolitan areas with alternative routes, as well as cases of simultaneously providing travel time information on parallel paths such as national and regular highways. For each case, we analyzed whether the provision of VMS traffic information leads to route changes and substantial effects. METHODS : To analyze traffic changes on the main and detour roads based on the detour information provided on traffic accidents in actual cases, the traffic volume and speed on the accident day were compared with those on the same days and at the same time of the day (regular days) based on the VDS data of the main and detour roads. Cases providing more detour information on road construction were investigated by examining three time periods: one week from construction initiation and one week before and after the construction period (regular days). The traffic volume and speed on the main road were compared based on the VDS data, and those on the detour road were compared based on data made available by private entities. Regarding the cases of simultaneously providing drivers with comparative information on travel time over parallel sections of national and regular highways, traffic situation changes in highways were analyzed in the following special traffic control periods (New Year's Day, NY Day), during which congestion is expected due to heavy traffic: before and after the provision of comparative information for 2015 New Year's Day and 2016 NY Day. RESULTS : The detour rate related to route changes based on the detour information for traffic accidents was 35%. On the detour route, the traffic volume increases as traffic from the main road is absorbed. However, the average travel speeds did not differ significantly. When further detour information regarding a road construction project was provided, the detour rate from the main road was 21%. The travel speeds were similar, except on the first day of construction. Almost no changes were observed in the first section of the detour. The speed slightly decreased in the second section but did not significantly hinder the traffic flow. When comparative traffic time information on parallel routes (national highways and expressways) was provided, the traffic volume increased to some extent after the report was provided for every case. However, the data frequency rate in the 5-min unit, which was still under the congestion speed standard (40 km/h), decreased. This indicates that traffic congestion was significantly relieved. CONCLUSIONS : Previous studies on detour rates or route changes based on VMS traffic information have focused on VMS instruments on expressways. Although their estimates were based on simulated situations, this study used actual VMS installed on national highways. In addition, this study utilizes the existing case records of national highway ITS centers, covering traffic situation monitoring, measures for accidental situations, etc., in regular times or special traffic control periods, as well as statistical data, including ITS real-time traffic information. The analysis results of this study accurately represent situations on actual roads and can be utilized to analyze future ITS operation and installation project effects.

Consumers visiting platforms that host user-generated content (UGC) not only consume content but also generate content by investing time and effort. This paper seeks to examine a UGC platform's content provision strategy: how a UGC platform can motivate consumers to generate UGC and how it can manage the balance between UGC and platform's own content. As UGC and the platform's own content perform the same function, one may be inclined to think that the two types of content are substitutes. Our analysis shows that they could function as strategic complements. This is because increasing the platform's own content provision raises the quality of content on the platform, motivates more consumers to join the platform, and increases the total UGC provision on the platform. The fact that consumers dislike advertising could lead us to believe that consumers will be less motivated to generate UGC if ad space increases. On the contrary, we find that consumers may be motivated to increase UGC provision to make up for the loss in enjoyment and increase the overall quality of contents on the platform. The public good characteristics of UGC could prompt us to think that UGC provision on the platform will be less than the socially optimal level. Our analysis identifies conditions when the total provision of UGC can be more than the social optimum. One may wonder whether it is profitable for a UGC platform to completely dispense with its own content. We find that it is always profitable for the UGC platform to offer some of its own content. This is because when consumers spend more time consuming the content, the platform can monetize their attention and earn higher ad revenue.

The Smart AtoN(Aids to Navigation) project aims to upgrade the facilities of AtoN to provide new additional information to nearby ships and unmanned ships. This paper deals with methods for collecting various sensor data through standardized interfaces; the NMEA-0183(serial line), the NMEA-2000(CAN), and the NMEA OneNet(IPv6). The AIS(Automatic Identification System) and the AIS-ASM(Application Specific Message) are considered as communication means for providing sensor information to nearby ships. In this paper, we summarize existing NMEA sentences for collecting sensor data and AIS-ASM messages that can be used to deliver sensor data to ships. Information provided from the smart AtoN through AIS, ASM, etc. may be presented on the shipborne displays that complies with the IEC62288:2021 standard.

Under Article 17 of the Radioactive Waste Management Act and Article 12 of the Enforcement Decree of the Radioactive Waste Management Act, KHNP shall reserve the cost for the decommissioning of NPPs as provisions. To preserve the value, an additional amount considering the discount rate is to be added annually. The initial provision is decided by estimating the decommissioning cost of NPP at the time of commercial operation, calculating the future cost by applying the inflation rate to the expected start date of decommissioning, and then discounting it at a discount rate to the present value. According to the current notice, the period for applying inflation and discount rate is defined as the period of 5 years added to the design life of NPP, which is presumed to be due to the assumption that all decommissioning costs are incurred at once 5 years after the permanent shutdown of the power plant. However, assuming that the actual decommissioning period of a domestic nuclear power plant is generally planned for 15 years, it can be expected that most of the decommissioning activities will begin after the decommissioning preparation and transition period, or 5 years after permanent shutdown of the plant. Considering this, it can be said that the current period (5 years + design life) for applying inflation and discount rate is set a little conservatively. In this paper, the initial provision is calculated by appropriately distributing the decommissioning costs of overseas NPPs categorized by International Structure for Decommissioning Costing (ISDC) during the planned decommissioning period of domestic NPPs, and then adding up the decommissioning cost each year by separately applying the inflation and discount period, which was compared with the results calculated using the current method. Through this, it was confirmed that the revised method had the effect of reducing the initial provision by 2.2% to 5.7% compared to the current method depending on the gap between inflation rate and discount rate, which can be converted to about 8 years of inflation and discount period used in the current method. It is expected that this paper will be used in the future as a basic reference for developing a more accurate method for calculating the initial provision of decommissioning cost.

This study was conducted to investigate the potential of toy provision for stress reduction, welfare improvement and toy preference in finishing pigs. Toy shape was expected to exert effects on stress related behaviors including fighting, bothering, and feed competition. Three different toy shapes (i.e. square, round, and oval) were given to groups of finishing pigs. A no toy control group was also included. The duration and frequency of abnormal behaviors and use time for toy preference were compared among groups. The duration and frequency of stress related behaviors was higher (p<0.01) among the non-toy-using finishing pigs on 20 minutes and 118 times than 16 minutes and 57 times of toy-using finishing pigs. Toy shape exerted no significant effects, however, toy use displayed a clear ability to reduce stress related behaviors among finishing pigs. Toy use time and shape both displayed no clear effect on the duration of stress related behaviors. These behaviors were most frequently displayed in the afternoons when the finishing pigs become most active, and were not affected by toy shape. Overall, the square shaped toy was used much longer (9.7 hours) and more frequently (566 times) in a 24 hour period by the finishing pigs (p<0.01). In conclusion, providing toys to finishing pigs reduces stress and stress related behaviors. This finding is expected to positively impact welfare and improve finishing pig productivity. Square shaped toys were most preferred by the finishing pigs, therefore adopting toys with square features is recommended.

1. 본 연구는 베트남 쌀 농장의 농업 기계화 서비스 제공의 재무 성과를 분석하였다. 2. 2014년 베트남 가계생활수준조사 결과를 활용하여 타 농가의 쌀 생산에 농업 기계화 서비스를 제공한 164명의 농가를 추출하였으며, 분석한 결과 해당 서비스의 제공이 농가당 약 1700 만 VND / 년의 수익을 발생시켰다는 것이 발견되었다. 3. 자산 감가 상각, 노동 아웃소싱, 농업 신용 및 쌀 토지 면적의 경우 그 값이 커질 수록 농업 서비스 제공자의 재정 효율성을 저하시키는 것으로 발견되었다. 4. 한편, 남성이거나 주 수입이 쌀 생산인 농부들은 재정적 효율성이 더 높은 것으로 분석되었다. 5. 본 연구는 베트남 농민들이 쌀 생산의 재정적 효율성 향 상에 농업 기계화가 긍정적인 영향을 주고 있음을 시사하지만, 농업 기계의 짧은 운용시간을 고려하였을 때 농업 기계 구입을 위한 신용 대출 정책에 있어 베트남 정부가 신중하게 접근할 필요가 있음을 제시하고 있다.

Background: Stroke patients experience multiple dysfunctions that include motor and sensory impairments. Therefore, new intervention methods require a gradational approach depending on functional levels of a stroke patient’s activity and should include cognition treatment to allow for a patient’s active participation in rehabilitation. Objects: This study investigates the effect of integrated revision of electrical sensory stimulation, which stimulates somatosensory and action observation training, which is synchronized cognition intervention method on stroke patients’ functions. Methods: Twenty-one stroke patients were randomized into two groups. The two groups underwent twenty minutes of intervention five times a week for three weeks. This study used an electromyogram to evaluate symmetric muscle activation of lower extremities and muscle onset time when performing sit to stand before and after intervention. A weight-bearing ratio was used to evaluate the weight-bearing of the affected side in a sit to standing. To evaluate sit to stand performance ability, this study performed five timed sit to stand tests. Results: The two groups both showed statistically significant improvement in muscle onset time of lower extremity, static balance ability in a standing position, and sit to stand performance after the intervention (p < 0.05). In addition, the action observation and synchronized electrical sensory stimulation group showed significant improvement in symmetric muscle activation of lower extremities and weight–bearing ratio of the affected side (p < 0.05). Conclusion: action observation and synchronized electrical sensory stimulation (AOT with ESS) can have positive effects on a stroke patient’s sit to stand performance, and the intervention method that provides integrated AOT with ESS can be used as new nervous system intervention program.

This paper tries to show the efficiency of water financing between central and local governments. From the year of 2017, the operation and maintenance costs for change water pipes has been provided by central government as block grants system(RDSA: Regional Development Special Account). Even though the water financing is responsible for local government, water drought and high production cost in poor area affects the quality of life nowadays. Then, fiscal transfer through block grant for water financing has been decided to invest regional SOC. The purpose of the paper sheds light on the function of the block grant for public provision by water financing. The firstly tried empirical results are based on the survey from local governments and ministry of environments. The point of the empirical analysis shows that the local governments does not have proper measurement for unexpected water leakage and termination until now. In a policy manner, the paper raises the issues about benefit principle for water users by the increase of tariffs. In order to do so, the paper investigates the relationship between the water provision and fiscal status of each local governments.

Risk information may be one of the most important factor for worker's safe behavior because that safe behavior can be oriented by attitude based on risk information. Traditionally KAP(knowledge, attitude and practice) model was useful frame for the change of human behavior. Knowledge is formed by information through experience and education. Worker's health may be prevented by his or her own active safe behavior based on risk information. This paper is to investigate the effect of labor union on the provirion of risk information by labor union. Data for analysis is the third Korean Working Conditions Survey done by Occupational Safety and Health Research Institute in 2011. The sample size is 50,032 economic active person surveyed by household interview survey with structure questionnaire by trained interviewer. The difference of risk information provision among employees was tested by mean difference test. The level of risk information of employees of companies with labor union is higher than that with non labour union. This paper has some implication for the promotion of safe behavior of employees through risk information provision mediated by labor union. Some limitation of this study may be considered because of using the cross sectional survey data.

입증책임이란 요건사실의 진위가 불명한 경우에 대처하여 요건사실의 부존재의 경우와 마찬가지로 취급하여 소송당사자 일방에 대하여 그에게 유리한 법규부적용의 불이익을 부담시켜서 판결을 가능하게 하는 것이다. 따라서 소송당사자의 승패에 결정적 역할을 한다. 이와 관련하여 상속이나 증여의 경우에는 납세자에게 자료가 편중되어 있어서 즉 증거의 거리와 증거의 지배를 대부분 납세의무자가 하고 있어서 과세관청에 입증의 곤란을 초래하기 때문에, 이러한 입증책임의 곤란의 문제를 해결하기 위해 다른 세법의 규정과 달리 많은 추정규정과 의제규정 두고 있다. 하지만 추정규정과 의제규정은 과세관청의 입증책임을 완화 또는 입증필요의 전환을 시키는 점에 있어서 입증책임분배원칙에 대한 예외에 해당할 수 있다. 따라서 이와 같은 입법은 되도록 제한할 필요가 있고, 그 해석도 엄격할 필요가 있다. 즉 납세의무자의 헌법 제23조의 재산권과 헌법 제27조의 재판받을 권리를 침해할 가능성을 내포하고 있는 점에서 국민의 예측가능성을 고려한 입법이 요구된다. 궁극적으로 조세법률주의를 실질적으로 잠탈 할 가능성이 있으므로 충분한 고려를 통한 입법이 요구된다. 특히 의제규정의 경우에는 추정규정과 달리 반증을 통한 번복 가능성이 존재하지 않으므로 국민의 구제가능성 어렵기 때문에 신중한 입법이 요구된다. 특히 명의신탁의 증여의제규정인 상증법 제45조의2와 관련하여 위헌가능성과 최근 대법원 판례의 ‘조세회피의 목적’과 관련된 변화된 입장을 고찰할 필요가 있다. 그리고 추정규정 중 재산취득자금의 증여추정 규정인 상증법 제45조 1항에서의 입증의 범위에 관하여 종전의 규정과 달리 ‘다른 자로부터’의 문구가 삭제되어 기존과 다른 입증책임론이 필요한 것이 아닌지 고찰할 필요가 있다.
