Background (Purpose): The objective of this study was to investigate regulations on pharmacist and other healthcare professional license examination in Korea. Specific aim was focused on the implementation of new regulatory system governing pharmacist license examination particularly on naming of the subjects, method of the examination, and discrimination of pass or fail. Method: Laws and regulations of Korea on the examination system were retrieved from sources posted in Ministry of Government Legislation. Results: Two major regulatory differences were found between pharmacist and other healthcare professionals license examination systems. Firstly, the regulation on pharmacist license examination was ruled by the enforcement ordinance of parent law (Pharmacy Law) while it was ruled by enforcement regulation of parent law (Medical Law). Secondly, minimum grade requirement for pharmacist and other healthcare professionals was differently set up: 40% for each single subject in pharmacist and average of 40% for each group of several subjects in other healthcare professionals. Conclusion: Since pharmacist profession has drastically changed from drug-makers to drug-users during the recent decades, it is desirable to have the regulations on pharmacist license examination system amended in harmony with other laws and regulations of Korea and other major developed countries. Two-step examination for pharmacist license appears worthwhile to implement for balancing the two key functions of the pharmacist being drug-makers and drug-users.

본 논문에서는 위성원격탐사의 제도적 정비와 향후 입법 과정에서의 사전 참고로서 이와 관련한 법적 문제들을 검토해 보았다. 위성원격탐사와 관련해서는 광범위한 법적 논점들이 제기될 수 있으나, 본 논문에서는 위성원격탐사에 관한 운용규제와 위성데이터의 거래규제 문제들에 논의의 중심을 두고, 우리법상의 본격적인 입법론적 방안을 위한 선행 연구로서, 비교법적 검토를 시도하였다. 먼저 위성원격탐사와 관련한 국제우주법 체제를 우주조약 체제와 UN원격탐사원칙으로 구분하여 개관하였고, 위성원격탐사에 관한 주요국의 입법례를 살펴보았다. 입법 연혁에 따라 미국, 캐나다, 독일, 프랑스, 일본의 순서로 각 법규들의 성립 배경과 구체적인 입법적 구조 및 주요 내용 등을 구체적으로 분석해 보았다. 이후, 비교법적 검토를 토대로, 위성원격탐사 법제 정비와 관련한 몇 가지 논점들을 상정하여, 시사점 내지 개별적인 의견 등을 제시하였다. 2020년 현재까지 '국내 입법'으로 위성원격탐사에 관한 법제 정비를 시도한 국가들로는 미국, 캐나다, 독일, 프랑스, 일본이 유일하다. 이들 국가들은 자체적인 위성 운용시스템과 위성데이터보호에 관한 입법적 체계를 마련하여, 위성원격탐사에 관한 법률적 규율을 실시하고 있다. 우리나라도 2010년부터 '천리안 위성'을 운용하며 해양·기상 관측을 행하고 있는 위성원격탐사 수행국이라 할 수 있는데, 아직 그와 관련한 법제는 몇 가지의 정부 훈령을 제외하고는 마련되지 않은 상황이다. 그러나 위성데이터의 활용 플랫폼이 큰 폭으로 변화하고 있고, 소형 관측위성의 개발도 고려할 수 있는 지금, 데이터에 대한 접근성과 활용도는 향후 큰 폭으로 상승할 것이다. 이러한 점들을 고려할 때, 우리나라에서도 관측위성시스템과 위성데이터를 종합적으로 관리할 수 있는 입법 추진이 필요할 것으로 보인다. 특히 국가안보와 정보보안의 측면에서도 위성데이터에 대한 일정한 보급규제가 제도적으로 필요할 것이다.

The purpose of this study is to find out a way to apply the strength of American homeowners association to Korean housing management system through literature review on the legal basis, organizational composition and functions, and management models of homeowners association. Following is distinctive characteristics of American homeowners association. 1) Homeowners association is a juridical entity which 'Condominium Act' obliges residents to join. 2) The board of directors is decision maker. The covenant, however, gives residents right to act in committees. 3) Homeowners association has self-governing functions such as management of common spaces, permission of new construction and taxation. 4) Types of management are volunteers' self-management, association-employed management, full agency management, and some mixed types. Residents pay management charge by month or by quarter. This study suggests as follow. 1) It is needed for Korea to legislate the law to regulate the management system of detached houses. 2)Management system of Korea can be more efficient with volunteers' committees for active participation. Above all, architectural control committee is essential in the circumstance that reform of apartment is popular these days. 3) The management entity is recommended to have some self-governing function to talk about taxation policy with local governments.

Based on a reduced displacement field, a layer-wise (LW) formulation is developed for analysis of thick shell panels which is subjected to axial tension. Employing the principle of minimum total potential energy, the local governing equations of thick panel which is subjected to axial extension are obtained. An analytical method is developed for solution of the governing equations for various edge conditions. The governing equations are solved for free and simply supported edge conditions. The interlaminar stresses in the panel are investigated by means of Hooke's law and also by means of integration of the equilibrium equations of elasticity. Dependency of the result upon the number of numerical layers in the layerwise theory (LWT) is studied. The accuracy of the numerical results is validated by comparison with the results of the finite element method and with other available results in the open literature and good agreement is seen between the results. Numerical results are then presented for the distribution of interlaminar normal and shear stresses within the symmetric and un-symmetric cross-ply thick panels with free and simply supported boundaries. The effects of the geometrical parameters such as radius to thickness and width to thickness ratio are investigated on the distribution of the interlaminar stresses in thick panels.

In the present work, free vibration of beams made of imperfect functionally graded materials (FGMs) including porosities is investigated. Because of faults during process of manufacture, micro voids or porosities may arise in the FGMs, and this situation causes imperfection in the structure. Therefore, material properties of the beams are assumed to vary continuously through the thickness direction according to the volume fraction of constituents described with the modified rule of mixture including porosity volume fraction which covers two types of porosity distribution over the cross section, i.e., even and uneven distributions. The governing equations of power law FGM (P-FGM) and sigmoid law FGM (S-FGM) beams are derived within the frame works of classical beam theory (CBT) and first order shear deformation beam theory (FSDBT). The resulting equations are solved using separation of variables technique and assuming FG beams are simply supported at both ends. To validate the results numerous comparisons are carried out with available results of open literature. The effects of types of volume fraction function, beam theory and porosity volume fraction, as well as the variations of volume fraction index, span to depth ratio and porosity volume fraction, on the first three non-dimensional frequencies are examined in detail.

The scaling laws for vibration response of anti-symmetrically laminated plates are derived by applying the similitude transformation to the governing differential equations directly. With this approach, a closed-form solution of the governing equations is not required. This is a significant advantage over the method employed by other researchers where similitude transformation is applied to the closed-form solution. The scaling laws are tested by comparing the similitude fundamental frequencies to the theoretical fundamental frequencies determined from the available closed-form solutions. In case of complete similitude, similitude solutions from the scaling laws exactly agree with the theoretical solutions. Sometimes, it may not be feasible to select the model which obeys the similarity requirement completely, therefore partial similitude is theoretically investigated and approximate scaling laws are recommended. The distorted models in stacking sequences and laminated material properties demonstrate reasonable accuracy. On the contrary, a model with distortion in fiber angle is not recommended. The derived scaling laws are very useful to determine the vibration response of complex prototypes by performing the experiment on a model with required similarities.

A solution is presented for the computation of the elastic-creep stresses in a hollow cylinder subjected to nonaxisymmetric temperature distribution. The creep problem is treated by the Maxwell creep model. Laplace transformation is used for reformation of the governing equation of elastic problem and Hooke's law in a function of .gamma. , .theta. , and creep constant. The governing equation is set up using the Airy stress function which leads to the biharmonic equation. The solution is obtained by using Fourer series method and Laplace inverse method used to obtain the stress components which include the variation of time. This solution shows excellent agreement with Lamkin's and Boley & Weiner's solution. The viscoelastic stresses are also obtained for the fuel rob tube subjecting nonaxisymmetric thermal load.
