Some golf balls have wrong rotation axis owing to bad production and scratch. Dimples of golf ball make a golf ball higher and more straight flying. When we hit a golf ball by driver or iron club, the dimpled ball flies straight and rotates as well. While the ball flying, the rotating axis of the ball convergence. In this paper, we develop a control system to detect convergence axis and time of flying golf ball based on vision system.

Homogenization of quality was important in order to use herbal medicines as pharmaceuticals. To solve this problem, it was important to establish quality standards. Atractylodis Rhizoma Alba has no quantitative method in the Korean Pharmacopoeia. Thus, we have researched to improve the quality evaluation method of Atractylodis Rhizoma Alba with an HPLC. Atractylenolide Ⅲ and atracylodin were selected as potential marker compounds. This analytical procedure was subject to validation. According to validation guideline of South Korea’s Ministry of Food and Drugs Safety, the specificity, linearity, precision, range, quantitative limits, detection limits and accuracy were measured. Because the specificity, linearity, precision, range, quantitative limits, detection limits and accuracy meet criteria of the guideline, the analytic method was validated. With this analysis, Atractylodis Rhizoma Alba and Atractylodis Rhizoma analyzed. As a result, both atractylenolide Ⅲ and atracylodin appear to be suitable standard compounds. it confirmed that tractylodes Rhizome, similar to Atractylodes Rhizome Alba, could be distinguished.

Remuneration claims of unregistered mediation agent becomes a problem if the real estate contract of sale is signed after the arrangement of the intermediary remuneration between unregistered mediation agent and a client is made. The case where the unregistered mediation agent involves in the real estate is greatly diverse. There is a case where the unregistered mediation broker may be charged a brokerage remuneration for clients when signing the contract, such as real estate for sale as their work. Furthermore, there is also the case that unregistered mediation agent may be charged the brokerage remuneration for a licensed real estate agent when they enter into the contract, such as a joint meditation. According to the leading case, there are conclusions where the statutory arrangements for the remuneration of intermediaries between the unregistered intermediary agents and the client are in violation thus nulified. However, if unregistered mediation agent got the remuneration only once by chance from clients, the Supreme Court has determined that the remuneration arrangements do not violate the mandatory rules. Thus, the Supreme Court has different view about the same issues. In this research, the legal characteristics of remuneration claims of unregistered mediation agent with Japan’s precedents is discussed. In Japan’s case, remuneration problems is obligatio naturalis. Therefore, even if clients allow the payment of the intermediary remuneration to unregistered mediation agent without trial, and the unregistered mediation agent were received intermediary remuneration at the same time it won’t be an excessive profits. However, in the unregistered mediation agent’s case, check or payment of claims on maintenance claims in court could not be judged. This research agrees to the conclusion where the Japan’s precedent made, in the fundamental position. In other words, it is possible to make a well-balanced value judgment in on the concern between the purpose of regulations and judicial force. However, there are difficulties in applying this uniformly to Korea’s intermediation business as obligatio naturalis, unlike the cases of Japan. Therefore, we examined the basis of the doctrine and case law of Japan and review the question of obligatio naturalis, validity of the agreement of brokerage fees between unregistered mediation agent and clients, and if unregistered mediation agent gets the maintenance claims for clients, what will be the basis and foundation be.

수익형 부동산 개발사업의 리스크 관리방안 연구 - 분양형 호텔개발사업을 중심으로 -

이재웅 ( Lee Jae-woong ),박인 ( Park In ) 한국지역사회발전학회(구 한국지역사회개발학회) 2017 地域社會開發硏究 Vol.42 No.2

Recently, the Korean real estate market has become more interested in the profitable real estate market than the financial market due to the prolonged low interest rate and economic recession. In particular, interest in condominium hotels, which can continuously provide operating income due to increased tourism demand and leisure time, is increasing. However, as Korea's accommodation property market becomes more intense, the risk of investment in development of condominium hotel projects is increasing. Therefore, this study aimed to establish a plan for the successful development and operation of the condominium hotel by deriving the risk factors of the condominium hotel development project based on the multiple decision making technique (AHP). First, in order to reduce the risk of condominium development projects and increase the likelihood of project success, it is the most important to provide a favorable environment to attract tourists and guests considering accessibility and location. Various types of accommodation including hotels in Korea has become seriously competitive. Second, in order to reduce the risk of condominium hotel development projects, it is important to consider delays in obtaining permits and resolving complaints. Real estate development projects are characterized by getting approval and reducing the economic aspect. In general, it is important to consider the feasibility of financial costs and proprietary conditions. Third, as the condominium hotel development business generates profits through the management and operation based on rooms, it is considered to be the greatest risk to reduce profit due to vacancy and customer stagnation. Therefore, thorough preparation and planning are required. Finally, it was important to consider the cultural infrastructure of the surrounding environment and the environmental characteristics related to the hotel that can attract tourists and guests as a major revenue source for condominium hotels.

환경기 초시설의 성공적인 민영화를 위하여 환경보전이라는 사회적 동기와 이윤추구라는 기업의 경제적 동기를 동시에 만족시킬수 있는 정책이 필요하다 환경기초시설은 영리목적이 아니므로 양질의 환경서비 스를 달성하기 위한 민간경영마인드를 도입하여야 할 것이다 외국사례를 보면 지역의 안정된 경제적 바탕 위에 철 저한 경쟁을 통해 비용우위의 사업자를 선택하여 민영화를 실시하였다 따라서, 민관의 협력과 업무분담이 효율적이었고, 이들 위해서 는 무엇보다도 지자체의 독립적 예산 마련이 필수적임을 알 수 있었다. 그러나 국내 환경기초시설의 중요한 문제점으로 운영관리상의 낮은 효율과 기술적용에 있어 국산화율이 5 0%로 정부국고를 낭비하는 등 해결해야할 문제점이 많은 것으로 나타났다. 이를 해 결 하기 위해 민자유치촉진법 미비점 보완 시범 민영화 플랜트 운영과 효율적인 민영화를 위한 연구사업추진, 외국의 사례연구 및 현장시찰, 환경기초시설을 지방자치의 경영수익사업으로서 확대발전을 통한 환경예산의 관리 및 지원체계를 마련하는 방안을 강구할 수 있었다. For succes:privatization privatization of environmemal facillity, a sound environmental policy is required to satisfy social motivation and economic. The prrmary purpose of environmental facility is not profit, but to supply a good quality service, an efficient management tool is needed to run the facility. In foreign countries, the privatization policy was originally based on the princile of complete competition achievingeconomic dffiency. There were effciet cooperation and division of Iabor between civillian and public sector. Firsr of all, the local govemmem had independant budget. But, we found that rhe envitonmental facility have two importanr problerns, the fìrst is Iow effiency of operation and rhe second is comswned to govemmem fìnances as a homemade rate 50% in the technic application For a successful privatization of rhe environmemal facility, The law of private capiral introduction should be amended to promote fund raising. There are some other sttategies; overrcoming of Nimbyism, research development of rhe privatization, field trip to rhe successful foreign environmental facilities. To suppon an efficient privatization policy, the environmental budget should be managed by cost-benefuit analysis.

이재웅(Jae-Woong Lee),남충희(Chunghee Nam) 한국자기학회 2020 韓國磁氣學會誌 Vol.30 No.5

AlFe₂B₂ is one of good candidates for the magnetic refrigerator with the magnetic cooling effect. In this study, we investigated the change of magnetocaloric properties by doping 1.5% and 5.0% of B in AlFe₂B. Structural phase analysis through X-ray diffraction was carried out to find the optimal conditions for the synthesis of AlFe₂B by arc-melting, and then analyzed AlFe₂B phase after posttreatment, such as acid-treatment and annealing. As a result of the structural phase analysis, the presence or absence of FeB impurities was determined according to the amount of doping in the post-treated AlFe2B2. Each sample was measured using Magnetic Properties Measurement System (MPMS) for magnetic properties. The magnetization and saturation magnetization in terms of temperature were measured, and the difference in magnetization value was observed according to the amount of B doping. The magnetic entropy change (˗ΔS) was calculated from the measured M-H data. ˗ΔS at 2 T has 2.01 J/kg∙K and 2.24 J/kg∙K for boron 1.5% and 5.0% doped samples, respectively. The difference between the magnetization values and ˗ΔS was due to the amount of FeB impurities produced by B doping.
