역운동학 알고리즘은 다관절체의 엔드 이펙터를 제어하기 위한 매우 유용한 방법이다. 대부분의 역운동학 처리 과정에서 주된 관심사는 다관절체가 가지는 자세의 형태 자체가 아니라 제어되는 다관절체의 엔드 이펙터의 위치와 방향이다. 그러나 삼차원 캐릭터 애니메이션과 같은 종류의 응용 분야에 있어서는 엔드 이펙터의 정확한 위치와 방향보다는 다관절체의 전체적으로 자연스러운 자세 자체가 훨씬 더 중요한 요소이다. 실제로 애니메이터가 기존의 역운동학 기법을 사용해서 인체와 같이 다수의 물리적인 제약조건을 가지는 인간형 삼차원 캐릭터의 자세를 자연스럽게 제어하기 위해서는 많은 시행착오를 겪어야만 하기 때문에 이를 보완하는 특별한 알고리즘이 요구된다. CCD(Cyclic Coordinate Descent) 알고리즘은 기하학적인 검색을 통해 원하는 위치에 엔드 이펙터를 위치시키는 해를 구하는 역운동학 방식의 하나로서 사용자 상호작용을 통한 다관절체의 자세 제어에 적합하다. 그러나 CCD 알고리즘의 해는 초기 자세에 강력하게 종속되어 있기 때문에 초기 자세에 따라서 서로 다른 많은 해들을 얻게 된다. 본 논문에서는 인간형 캐릭터의 자세 제어를 위해 균등 자세 지도를 이용한 귀납적 역운동학 알고리즘을 제안한다. 균등자세 지도의 학습 알고리즘은 인간의 다양한 자세를 왜곡 없이 양자화하기 때문에 균등 자세 지도를 이용해서 기술되는 모든 자세들은 사실적인 자세임을 보장한다. 그러므로 균등 자세 지도를 통해 계산된 다관절체의 엔드 이펙터가 원하는 삼차원 위치와 가장 가까운 자세를 추출해 냄으로써 자연스러운 자세를 가지는 역운동학의 결과를 얻을 수 있다. 이러한 방식은 키 프레임 기반 삼차원 캐릭터 애니메이션의 제작과 3차원 게임, 그리고 가상 현실 등의 분야에 유용하게 적용될 수 있다.

본 연구의 목적은 대학 교양과목으로 개설된 '유튜브 영상을 활용한 대학생들의 인성교육'을 수강한 대학생들에게 인성을 주제로 한 UCC를 과제로 제작하는 것이다. 최근 학습자 교육의 패러다임 전환 속에서도 여전히 교수자 중심의 교육이 학습자의 참여의욕을 저해한다. 이를 해결하기 위해서 학습자주도의 UCC 제작과정은 효과적인 학습자 중심교육의 실천을 위해 필요하다 할 것이다. 연구목적을 달성하기 위해 현상학적 연구방법을 적용하였다. 연구 참여자들은 10명이고 자료수집을 위해 심층면담을 실시하였으며. 수집된 자료는 Colaizzi의 연구방법으로 분석하였다. 분석 결과, 9개의 주제와 4개의 주제 묶음, 그리고 2개의 범주로 도출되었다. 연구 결과는 다음과 같이 나타났다. 첫째, 연구 참여자들은 UCC 과제가 바른 생각과 행동으로의 실천 그리고 인성 개념의 재정립 등 성숙의 장으로 인식하고 있었다. 둘째, 그들은 UCC 제작 과정이 자존감을 높여주는 기회가 되었다고 하였다. 셋째, 그들은 UCC 과제가 자신을 넘어 타인에게 관심을 기울이는 계기가 되었다고 인식함으로 보다 성숙해진 인성을 보여주었다. 넷째, 그들은 UCC 과제를 수행하면서 주제 선정에 가장 큰 어려움을 겪었고, UCC 제작의 기술적인 미숙으로 인해 질 좋은 과제의 한계를 경험하고 있었다. 이러한 결과는 학습자들이 주도하여 제작하는 과제개발의 필요성과 이를 공유할 수 있는 상호작용의 장이 마련될 때, 보다 효과적인 인성교육을 기대할수 있다는 시사점을 제공한다.

This investigation aims at the optimum mixing of flexible flowable-fill made of Bottom-ash as an industrial waste. Flowable-fill refer to self-compacted, cementitious material used primarily as a backfill in lieu of compacted fill. The two primary advantages of flowable fill over traditional methods are its ease of placement and the elimination of settlement. Therefore, in difficult compaction areas or areas where settlement is a concern, flowable fill should be considered. This study compares Bottom-ash with fine aggregate in physical character. The mixing design indicates a various mixing-rate.

Conservation is the optimum sustained use of natural resources; therefore, cave conservation must provide not only for the protection of the character, decoration and biota of caves, but also for the means whereby people might enjoy and understand the caves that are their heritage. A cave is a natural subterranean cavity into which a man can enter to a point where daylight cannot be seen. Caves are not only interesting physical entities that provide distinctive sensory and perceptual experiences and invoke a variety of responses, but they also provide unique opportunities for scientific study. Speleology is the study of caves, and in New Zealand it attracts workers from many disciplines of the universities and government research establishments.(omitted)

The crystals of ${\beta}-and\;{\beta}'-(ET)_2ICl_2$ have a modified structure of organic superconductor ${\beta}(ET)_2I_3$. These salts possess strictly different physical properties : the ${\beta}$ phase is a metal but the ${\beta}'$ phase is a semiconductor. Our band electronic structure calculations show that the ${\beta}$ phase is somewhat anisotropic 2D metal and the ${\beta}'$ phase with the 1D character in electronic structure is magnetic insulating, in good agreement with experimental indications.

Efficient space plans are built upon relations of both human and physical compositions, and the standard of the interaction is basically the human scale. Especially in medical areas, the character of the users within human scale design environment is quite significant. Unlike large hospitals with great plans and scalability performed by experts, mid-sized clinics tend to have limited space, designed by non-specialists who highlight aesthetics over functionality in floor plans which leads to poor quality in medical service. For this reason, this study will include the application of human scale based therapy rooms within the clinic from a physical standpoint and will further analyze and pinpoint any room for improvement to further enable more efficient ergonomic space planning. In this study, theoretically will contemplate over human scale, mid-sized clinic, therapies, and therapists, while the case study will include status of the recent human scale based mid-sized clinic from a physical viewpoint, classification and analysis amongst human and physical compositions chosen by discretion from either a newly opened or a newly re-modeled clinic within the last 2 years, which has 15 beds or more, minimum 3 physical therapists, with more than 5 different therapy facilities in the metropolitan area in order to measure the human scale of therapy rooms in a mid-sized clinic. As a result, the area where improvement can practically be applied is the physical composition, which does not include human scale like human composition factors as therapists and patients, and hence, I suggest the human scale applied efficient medical space plan become the base of this study and look forward to subsequent improvement in the quality of medical services.

This study is search for analyzed the primary factor of psychological characters of crippled person toward psychological rehabilitation that is the most foundmental to all rehabilitation for a crippled person. The research is, make a comparative analyze to personality character, value character, and motion, and then examined the relation of among then, by applies to high school's crippled students. First. in the personality character aspect, a group of crippled student's is shown that the factor of family relations is lack harmony than normal group, that is, shown up that a parents and family members is oversensitiveness to crippled person, So sometimes they overprotectiveness, unconcered, and not accept it is. Also, in the factor of confrontability aspect, a group of crippled person's average is shown to high as compared with normal group, and then, it shown that they are irresponsible, have a weak self-control, and show a marked trend toward self-control. This is means that crippled person have scruples about psychological and social adaptation. But friendship, adaptability, cheefulness. and emotonal stability is shown no difference with normal person. Accordingly, in the personality aspect, the falter of family-relation and confrontability can be know that the object of psychological rehabilitation. Second, in the sence of value aspect, crippled students is show that the average score had higher than normal group toward the factor of variety, therefor we can know that they have purpose to more pursur of variety in the living. This is consideration that a raise from the limited of social contact chance and badly informed and experience. Also, the factor of purpose-intention is shown that crippled students had low non than normal group, then, that means that they have a weak will toward cope with various problems in daily living. Crippled student is, in contrast to lacked fixed purpose with self-living, and also insufficient tring to accomplish their objects. Third, crippled students motion shown that related to low level of personality character and a sence of value factor. Daily living activity is show that related to the factors of confrontability and cheerfulness. This means that rehabilitation service given a change to confrontability and cheerfulness that can be effect is related. And the activity of home is related with confrontability, psychological rehabilitation for the change of activity is can say that it should be contribute to strengthen toward responsibility and self-control from self-central to intention at rho others. Fourth, the relation between an motion and a value of crippled student is shown low level of regulations that can be ignore. In sum, in the rehabilitation of crippled person, hereafter, a study subject is if which search to character factor and to find out effect inter-factors within the the factor of psychological rehabilitation as medical, occupational, social rehabilitation, then probably more effective development toward rehabilitation programs. Conseguently, hereafter for the crippled person's rehabilitaton, the study should be rquirement for establish a character and factors each filed of rehabilitation. The study sibject toward crippled person's rehabilitation for the fature is search for character factor toward medical. occupational, and social rehabilitation. and find out inter-relation among then like as search of this study for psychological rehabilitation. For the rehabilitation of crippled person, if is not preceding of study like this, it ought to be difficult to creation service as well as development to effective program.

The multi-year production cycle for ginseng can be rapidly depreciated by inferior post-harvest activities. This research examines the character of high temperature drying regimes for North American ginseng root to assist management decision making. The objective is a very rapid drying regime, that will not result in physical or chemical damage to the root and that would not alter the actual dry root weight. Research is presented using drying temperatures of 55, 70 and 105 C. Temperatures above these rapidly cause substantive physical damage to the root samples and seriously compromise the dry root values determined. Temperatures below these behaved quite similar to actual dryer regimes (approximately 38 C). Laboratory results indicate that there are differences between the three temperature regimes tested. Careful usage of the 70 C regime, over a period of two to three days in a convection drying oven, has distinct merit.
