The skin-tone in portrait photography is one of the most sensitive parts that need retouching by a photographer. To investigate the emotional reactions related to users' preferences for the skin-tone variations in portrait photography, two experiments were conducted. The first experiment included JND(Just Noticeable Difference) test to determine the general distribution of preferences with many photographs that varied in phases up to an extreme one, as a result, preferences for the brightest skin-tone and the red or magenta one were found. Based on the first experiment, we reduced the number of samples by adjusting their brightness to the brightest phase constantly. To intensify the second experiment, we reduced the number of the other colored samples to only one and made samples for five phases from green to magenta, namely the most preferred skin-tone in the first experiment. In the second experiment, the common preference for a neutral skin-tone and the partial difference between the two gender groups were found. In conclusion, the users' preference for a particular skin-tone was positively affected by emotions such as 'happiness' or 'comfortable'. With this investigation, we compiled some statistically meaningful facts to confirm that the preferences of the users depend positively on controlling the skin-tone in portrait photography.

Last year, the Moon Jae-In administration made an attempt to abolish the presidential security office overseeing the presidential security and to transfer the work to the presidential security service under the National Police Agency. Currently, all of the G7 nations maintain a security system spearheaded by the police, so the policy of transferring the presidential security to the National Police Agency may be discussed. However, it is necessary to focus on the following reality. First, the current presidential security system is consisted of the overlapping security organizations classified into (1) inner ring of the presidential security agency, (2) middle ring of the police agency, and (3) outer ring of the capital defense command. If the presidential security agency is abolished, a vacuum will result as per the principle of class. Second, for the efficient security guard of the President, currently, the presidential security agency at the Presidential Security Safety Measure Committee plays the role of coordinating the tasks. If the National Police Agency becomes the control tower of the presidential security, whether command will be available for the military and diplomatic aspects of the presidential security work should also be considered. Third, Korea is currently in a truce with North Korea, so there is a big difference in terms of the security environment with such G7 nations as the UK, Germany, France, and Japan.

National libraries have an obligation to meet the information needs of users by collecting as many various materials as possible. As legal deposit accounts for the highest percentage of the collection building methods of national libraries, they are trying to encourage the legal deposit of the publishers. However, the rate of legal deposit for the most publishers are pretty low. Therefore, in this study, the improvement plans of legal deposit system for the purpose of helping legal deposit of national libraries improve smoothly has been investigated by identifying the problems with the legal deposit system that publishers had and by suggesting the matters that should be improved based on the recognition of legal deposit by publishers. The plans for the revitalization of legal deposit for the publishers are as follows: promoting factors of legal deposit systems such as scope, deadline, compensation, fine and legal deposit libraries, simplification of legal deposit procedures, set-up of automated online system for legal deposit and strengthening of the method for promoting and educating the legal deposit.

본 논문에서는 스윕곡면(sweep surface)을 기반으로 복잡한 3차원 물체의 형상을 변형하는 새로운 자유형상 변형(free-form deformation)기법을 제시한다. 본 논문에서 제시한 방법은 기존의 격자점(control lattices)을 조정하는 체적기반의 방법에 비해 스윕기반의 절차적 (procedural) 모델링 기법의 직관성을 활용하여 사용자에게 보다 효율적인 형상변형 기법을 제공한다. 3차원 물체의 정점들은 스윕곡면의 단면(cross-section)에 바인딩(binding) 되어 곡면의 변화에 따라 형상변형을 한다. 본 논문에서 제시한 스윕기반 형상변형 기법은 3차원 물체를 부분적으로 변형하는 기법과 계층구조를 기반으로 전반적인 형상을 변형하는 기법으로 구분된다. 부분적인 형상변형 기법은 스윕곡면을 구성하는 성분의 다단계(multi-level) 표현을 통하여 사용자에게 다중해상도(multi-resolution) 형상변형 기능을 제공한다. 계층구조에 기반한 형상변형 기법은 복잡한 3차원 물체를 위상구조에 따라 여러 계층으로 분할하고, 각 부분의 형상을 근사하는 스윕곡면들을 생성한다. 분할된 각 부분의 정점(vertices)들은 해당 스윕곡면에 바인딩 되어 스윕곡면의 단면의 변화를 따르게 된다. 이러한 상황하에서 스윕곡면들은 3차원 물체의 계층구조에 따라서 서로 상호작용(interaction)을 하게 되고, 결과적으로 3차원 물체의 각부분은 상호반응적 형상변형을 한다. 이러한 계층구조에 기반한 상호반응적 형상변형 기법은 사용자의 의도에 부합하는 보다 사실적이고 기능적인 형상변형을 가능하게 한다. 본 논문에서는 다양한 3차원 물체에 대한 실험을 통해 제시된 방법의 효율성을 입증한다. 결과 막성 사구체병증과 같은 신질환이 발견될 수 있으므로 신조직검사의 적응증에 합당한 경우 적극적인 신조직검사를 시행하여 원인 질환을 찾는 노력이 필요할 것으로 사료된다.. 남아가 75명으로 남녀비는 3.6:1을 보였다. 임상병리학적 분류상 일차성 신증후군이 89명(92.7%), 이차성 신증후군이 7명(7.3%)이었으며 일차성 신증후군에서 minimal change nephrotic syndrome이 71명으로 79.8%, focal segmental glomerulosclerosis 11.2%, mesangial proliferation 4.5%, membranoprolifrative glomeulonephritis 3.4%, membranous nephropathy 1명 1.1%이었으며 2차성 신증후군은 $Henoch-Sch\"{o}nlein$ nephritis가 3례로 가장 많았다. 미세변화 신증후군 71명 중 비재발군이 16명으로 22.5%, 비빈발 재발군 49.3%, 빈발 재발군 18.3%, 스테로이드 의존군 9.9%를 보였다. 결론 : 대전시에서의 신증후군 환아의 발생빈도는 15세이하 소아 10만명당 약 5명으로 추정되었으며 10여 년전과 비교하여 큰 변화를 보이지는 않았다. 또한 저자들의 임상병리학적 연구결과가 다른 문헌에서 보고된 소아 신증후군의 연구결과와 큰 차이를 보이지 않음을 알 수 있었다. 자극에 차이가 있지 않나 추측되며 이에 관한 추후 연구가 요망된다. 총대장통과시간의 단축은 결장 분절 모두에서 줄어들어 나타났으나 좌측결장 통과시간의 감소 및 이로 인한 이 부위의 통과시간 비율의 저하가 가장 주요하였다. 이러한 결과는 차가운 생수 섭취가 주로 결장 근위부를 자극하는

This study is the first part of the investigation of the students' and teachers' understanding of ideal conditions in physics. To do this, here, we provided the theoretical basis for the above study by discussing the meaning and characteristics of idealization. Idealization, introduced and elaborated by Galileo therefore characterized the nature of modem science, can be generated by four procedures: neglecting the minor variables, giving without any description about the minor variables, assuming the limit case, assuming constancy or uniformity. Idealization generated by these procedures can produce models and laws from the sensory informations about real world. And physics world is constructed by formalization or mathematization of these models and laws obtained through idealization about real world. Therefore, it can be said that idealization have a major role in the context of discovery. By this aspects, physics world can be viewed as the approximation of the real world, and this view, again, give rise the philosophical debate about the reality in nature. Idealization take an important role in the process of application of physics world and the understanding the real world. That is, physicists accept the discrepancies between real world, and physics world and make a great effort to explain, moreover, reduce these discrepancies by modifying or eliminating idealization involved in physics world. Continued from this study, we will proceed to obtain the implications of idealization on the physics learning and investigate the students' and teachers' understanding of the ideal condition involved in the theoretical explanation and the experiment in physics.

This study was conducted to improve the insufficiency of fruit vegetable grafting system developed by National Institute of Agricultural Sciences, Rural Development Administration. When the rotary blade cut the stem of scions and rootstocks, the grafting failure at curved cutting surfaces happened. The cutting depth of a tomato seedling by a rotated cutter was calculated 0.11 mm even when the cutting arm length and the maximum stem diameter were 50 mm and 5 mm, respectively. Mathematical analysis and high-speed photography showed that there was no problem by cutting in straight the stem of scions and rootstocks. The compression test of seedling stems to design the optimal shape of gripper showed that stems were not completely restored when they were compressed above 0.8 mm and 0.6 mm in case of rootstocks and scion, respectively. This study found that the bending angle of stem of tomato seedlings at the grafting period was 10 degree on average. The optimal gripper finger was the edge finger type which could be precisely set center point by adjusting the distance between fingers. In addition, it was found that most of seedling could be grasped without damage when the finger-to-finger distances is set to 2.5 mm for scion and 3.0 mm for rootstocks and finger are coated by 1 mm-thick flexible material.

질적 보장은 전문직 종사자에 의하여 수혜받는 대상자를 보호하기 위하여 전적으로 필요한 프로그램이다. 이러한 질적보장을 통하여 전문직의 자율성과 책임을 튼튼히 할 수 있는 의무는 전문직 종사자 모두의 관심사가 되어야 한다. 미국에 있어서 질적 간호에 대한 관심은 이제 새로운 이유가 아니다. Beyers(1988)는 건강체계 지도자 사이에 가장 중요한 문제로 강조하는 것이 수혜자의 이용의 용이성(Access), 숫가(Cost) 그리고 질적인 제공(Quality)이 라고 피력 하였다. 미국 건강사업 평가자와 조정자(Regulator)들은 질(Quality)을 위한 자율적인 프로그램에 많은 에너지를 투입하여 전반적인 건강사업 즉 의료계의 질보장, 더 나아가서는 간호의 질을 향상 시키기 위한 많은 프로그램을 분석 연구한다. 이 논문은 간호에 있어서 질적 보장을 위한 내용으로 주요점은 질적 보장에 사용되는 용어, 역사적 배경, 질적 보장을 강조하는 이유, 질적 보장제도의 개발, 질 사정(euali assessment)과 질적 보장에 있어서 간호 전문직 개입을 차례대로 설명하였다. 구미의 경우 1970년대부터 간호직에 있어서는 질적보장제도개발에 우선순위를 두게되어 미 간호협회에서는 Professional Standards Review Organizations (PSRO)에 근거하여 간호실무를 위한 표준을 내어놓았다. 질적보장을 위한 평가방법으로 구조, 과정, 결과 그리고 수혜자가 간호계획을 세우는데 사정에 참여하는 방법 등 4가지를 간략하게 설명하였다. 질적 보장을 향상시키기 위해서는 전문직과 공공의료기간이 서로 협동체가 되어 중추역할을 해야함을 강조하고 이렇게 서로 협력하므로써만이 비로서 우리의 목적을 성취할 수 있다고 생각된다.구 등이 이용된다. $^{166}$ Ho, $^{198}$ Au, $^{32}$P, $^{90}$ Y, $^{169}$ Er, $^{186}$ Rc, $^{131}$ I, $^{211}$ At 등 의 방사성 핵종의 교질, 미소구 또는 단세포군 항체표지 형태로 직접 종양내 또는 공동이나 체강에 투여하는 치료법이 있다. 류마치스 관절염의 슬관절에 $^{165}$ Dy colloid를 주사하는 $^{166}$ Ho-MAA도 활발히 이용되고 있다. and computed groundwater levels. 본 논문에서는 가파른 산사면에서 산사태의 발생을 예측하기 위한 수문학적 인 지하수 흐름 모델을 개발하였다. 이 모델은 물리적인 개념에 기본하였으며, Lumped-parameter를 이용하였다. 개발된 지하수 흐름 모델은 두 모델을 조합하여 구성되어 있으며, 비포화대 흐름을 위해서는 수정된 abcd 모델을, 포화대 흐름에 대해서는 시간 지체 효과를 고려할 수 있는 선형 저수지 모델을 이용하였다. 지하수 흐름 모델은 토층의 두께, 산사면의 경사각, 포화투수계수, 잠재 증발산 량과 같은 불확실한 상수들과 a, b, c, 그리고 K와 같은 자유모델변수들을 가진다. 자유모델변수들은 유입-유출 자료들로부터 평가할 수 있으며, 이를 위해서 본 논문에서는 Gauss-Newton 방법을 이용한 Bard 알고리즘을 사용하였다. 서울 구로구 시흥동 산사태 발생 지역의 산사면에 대하여 개발된 모델을 적용하여 예제 해석을 수행함으로써, 지하수 흐름 모델이 산사태 발생

This study demonstrated the effect of IT Ssupports for Iintegration Ccompetency(ITSIC) on organizational performance by using organizational temperance and absorption capacity as medium. The research model was verified with Smart PLS 3.0 based on the survey conducted overa total a total of of 126 pparticipantseople's surveys for the employees. First, the ITSIC had a positive effect on both the alignment and adaptability and also on absorption capacity. Second, it was confirmed that organizational temperance hads a positive effect on absorption capacity. Third, when the organizational temperance was mediated in the relationship between ITSIC and absorption capacity, it had a indicated a positive effect. Fourth, absorption capacity had a positive impact on organizational performance. The implications of this study differ from the existing studies through by validating validation of correlations correlations by extending IT technology and organizational performance to organizational ethical factors. In addition, it has been established that the ethical factors of the organization also act as leading factors of absorption capacity. ITSIC helps managers make balanced decision-making, which can contribute to improving absorption capacity by giving members a positive perception, ultimately having a positive impact on organizational performance. It suggests the importance of building appropriate IT infrastructure and cultivating organizational virtues in order to improve the performance of organizations in which absorption capacity is essential.

Recently, adipose mesenchymal stem cells (AdMSC) that are similar to bone marrow MSC and blood derived MSC are thought to be another source for stem cell therapy. However, the diseases that can be applied for stem cells therapy are age-dependent degenerative diseases. Accordingly, the present study investigated the growth and differentiation potential to neural cells of human AdMSC (hAdMSC) obtained from aged thirty, forty and fifty. The growth of cells and cell viability were measured by passage and neural differentiation of hAdMSC was induced in neural differentiation condition for 10 days. Our results demonstrated that cell number, viability and morphology were not different from hAdMSC by age and passage. Immunofluorescence analysis of neural cell marker (TuJ1, NSE, Sox2, GFAP or MAP2) demonstrated no significant differences in neural cell differentiation by age and passage. As the number of passage was increased, the mRNA level of MAP2 and Sox2 was decreased in hAdMSC from age of 50 compared to hAdMSC from age of 30. In conclusion, the present study demonstrated that ability of neural cell differentiation of hAdMSC was maintained with ages, suggesting that autologous stem cells from aged people can be applied for stem cell therapy with age-dependent neural disease with the same stem cell quality and ability as stem cell derived from young age.

The aim of this paper is to evaluate policy impact of Inno-biz verification and Venture verification, especially focusing on the complementarity effect according to the overlapped support in Korean ICT industry. Alongside the implementation of various government innovation policies, discussions regarding evaluations of such policies have been consistently undertaken in economics, because it is very important to evaluate whether public policies have played a proper role. However, one of the distinguished point of this research from previous studies is that this paper not only includes evaluations of a single policy, but also the discussion about interaction between different innovation policies. The main result of this paper is that, in the case of overlapping homogeneous policies such as Inno-biz and venture verification, the complementarity effect is negative. Compared with previous studies, the uniqueness of this research is as follows. First, deviating from the view of previous studies that focused on the evaluation of a single policy, this paper has considered interactions and the complementarity effect of innovation policy through "policy mix," an economic term. Second, based on this concept, the paper suggests an analysis framework for the evaluation of interactions and the complementarity effect of innovation policy.
