Objectives: The aims of this study were to quantify tug-back by measuring the pulling force and investigate the correlation of clinical tug-back pulling force with in vitro gutta-percha (GP) cone adaptation score using micro-computed tomography (${\mu}CT$). Materials and Methods: Twenty-eight roots from human single-rooted teeth were divided into 2 groups. In the ProTaper Next (PTN) group, root canals were prepared with PTN, and in the ProFile (PF) group, root canals were prepared using PF (n = 14). The degree of tug-back was scored after selecting taper-matched GP cones. A novel method using a spring balance was designed to quantify the tug-back by measuring the pulling force. The correlation between tug-back scores, pulling force, and percentage of the gutta-percha occupied area (pGPOA) within apical 3 mm was investigated using ${\mu}CT$. The data were analyzed using Pearson's correlation analysis, one-way analysis of variance (ANOVA) and Tukey's test. Results: Specimens with a strong tug-back had a mean pulling force of 1.24 N (range, 0.15-1.70 N). This study showed a positive correlation between tug-back score, pulling force, and pGPOA. However, there was no significant difference in these factors between the PTN and PF groups. Regardless of the groups, pGPOA and pulling force were significantly higher in the specimens with a higher tug-back score (p < 0.05). Conclusions: The degree of subjective tug-back was a definitive determinant for master cone adaptation in the root canal. The use of the tug-back scoring system and pulling force allows the interpretation of subjective tug-back in a more objective and quantitative manner.

Purpose: The purpose of this study was to investigate pain relief and functional recovery after total knee replacement. Methods: The treatment was performed by dividing individuals into a control group ($n_1=5$), ultrasound treatment group ($n_2=5$), and micro-current treatment group ($n_3=5$). The control group applied the hot pack for 15 minutes, Transcutaneous Electrical Nerve Stimulation (TENS) for 15 minutes, and Continuous Passive Movement (CPM) for 40 minutes. The ultrasound therapy group applied the frequency of 1 MHz, intensity of 1.0 $W/cm^2$ for five minutes following the same treatment as the control group. The micro-current therapy group applied the intensity of 25 ${\mu}A$, and pulsation frequency 5 pps for 15 minutes following the same treatment as the control group. After treatment, Visual Analogue Scale (VAS), Korean Western Ontario and McMaster Universities Arthritis Index (K-WOMAC), Berg Balance Scale (BBS), Range of Movement (ROM) and wound length was measured. Results: VAS showed significant effect in the control group and micro-current therapy group during the treatment period. According to the treatment of K-WOMACK, BBS, ROM, and Healing wounds showed main effects between groups. Conclusion: According to the results of this study, data showed improvement of pain relief, wound healing effects, and range of motion recovery. Thus, these selected treatments were effective after total knee replacement. In other words, electrical treatment continues to influence pain relief and functional recovery after total knee replacement.

Cleft lip and palate is one of the congenital anomalies which need comprehensive and multidisciplinary treatment plan because 1) oral cavity is an important organ with masticatory function as a start of digestive tract, 2) anatomic symmetry and balance is esthetically important in midfacial area, and 3) it is also important to prevent psycho-social problems by adequate restoration of normal facial appearance. There are many different protocols in the treatment of cleft lip and palate, but our department has adopted and modified the $Z{\"{u}}rich$ protocol, as published in the Journal of Korean Cleft Lip and Palate Association in 1998. The first challenge is feeding. Type of feeding aid ranges from simple obturators to active orthopedic appliances. In our department we use passive-type plate made up of soft and hard acrylic resin which permits normal maxillary growth. We use Millard's method to restore normal appearance and function of unilateral complete cleft lip. In consideration of both maxillary growth and phonetic problems, we first close soft palate at 18 months of age and delay the hard palate palatoplasty until 4 to 5 years of age. When soft palate is closed, posterior third of the hard palate is intentionally not denuded to allow normal maxillary growth. In hard palate palatoplasty the mucoperiosteum of affected site is not mobilized to permit residual growth of the maxilla. We have treated a patient with unilateral complete cleft lip and palate by Ajou protocol, which is a kind of modified $Z{\"{u}}rich$ protocol. It is as follows: Infantile orthopedics with passive-type plate such as Hotz plate, cheiloplasty with Millard's rotation-advancement flap, and two stage palatoplasty. It is followed by orthodontic treatment and secondary osteoplasty to augment cleft alveolus, orthognathic surgery, and finally rehabilitation with conventional prosthodontic treatment or implant installation. The result was good up to now, but we are later to investigate the final result with longitudinal follow-up study according to master plan by Ajou protocol.

The purpose of this study was to develop a curriculum for the oriental clinical nurse specialist program based on the understanding of Korean human beings so as to develop nursing as a profession and promote the client's health. The design of this study was based on literature review and nominal group study. The research was managed by East-West Nursing Research Institute of nursing science college at Kyung Hee University. The research team was composed of 17 professors of nursing departments of oriental medical colleges. We obtained opinions from Oriental Nurses Association, Oriental Nursing Research Association, and professors in oriental medical college. We reviewed articles, curriculums of other clinical nurse specialist programs, medical laws and the curriculum development plan for the oriental clinical nurse specialist program from Korean Nurses Association. We discussed a curriculum thoroughly in numerous meetings. We developed a following curriculum: 1. Educational philosophy was founded on the oriental human view which was based on Chun-In union theory. It was founded on the oriental health view which recognized health being in harmony with nature and the balance of body function with the harmony of Yin-Yang in the five elements. In addition, it was founded on oriental nursing view to promote these health states. 2. Educational goals were to train oriental clinical nurse specialists, oriental nursing educators and oriental nursing researchers who developed knowledge of oriental nursing theory, nursing practice and created a leadership. 3. Curriculum consisted of 48 credits, of which 36 credits are based on lectures and laboratory classes and 12 credits are based on clinical practice. 36 credits consisted of 5 general subject credits and 31 core subject credits. General subjects consisted of nursing theory, nursing research, law and ethics. Students who had earned master's degrees are not required to take the general subjects. Core subjects consisted of 11 subjects such as advanced physical examination and laboratory, oriental nursing theory, original text of oriental nursing, oriental medical nursing, oriental pediatric nursing, oriental gynecologic nursing, oriental gerontologic nursing, oriental pharmacology, oriental constitutional nursing, advanced nursing of channels and acupuncture points and laboratory and oriental rehabilitation nursing and laboratory. In addition, clinical practice in a hospital ward, out patient department, herb prepation room, department of physical therapy and health promotion center in oriental medical hospitals for 12 weeks. To admit this program, students should complete prerequisites of introduction to oriental nursing and nursing of channels and acupuncture points. 4. Course contents of each subjects were developed to include the course's goal and objectives and specific items. 5. Evaluation involved lecture, laboratory and in field practice. We applied various evaluation systems and methods that were based on both knowledge and skills of the students to ensure full credibility and validity.

Since Korea disclaimed to open the ports, Korean architecture has met the impetuous transformation. Although there would be various factors of this transformation, the new-coming architecture by missionary seemed to be a significant one, and many researches have been carried out on this theme in diverse viewpoints. However, because these researches have preponderated on the Catholic tradition, it is deficient for clarify the whole history of mission architecture. Therefore, this research has the meaning to enrich the history of Korean modern architecture by making balance. First of all, this paper is focused on the activities of one missionary, Graham Lee. He is a practical missionary at the beginning, his architecture made a critical influence in Korean traditional architecture. Graham Lee was born in Rock Island, Illinois, 1861, and he determined to become a missionary through grown up. He spent his boyhood by working as a plumber for his purpose and studied in a university afterward. Graduating of McComick Theological Seminary, he was nominated as a pioneer of Pyeng Yang Mission Station and set foot in Korea, September of 1892. Since then he started to erect missionary facilities in Pyeng Yang, such as Well House(1898), Pyeng Yang Central Church(1900-1901), Pyeng Yang Academy(1902). These all his works are designed with eclectic style which shows western and Korean traditional style intermingled. This unique characteristic made a profound influence to the Korean mission architecture afterwards. Especially, the L-type plan of Pyeng Yang Central Church, which is first shown by him, is recognized very unique, and this plan type had been spread all over the country. Therefore the L-type plan became the peculiar feature of the early Korean churches. Furthermore, working with Korean carpenters, he taught them new skills of modem buildings. After that, they were expanded out northern part of Korea and took the roles of master builders. According to this expansion, his particular style had got spread and had been settled as a unique eclectic style in Korean modern architecture. In the conclusion, he is evaluated to be a critical pioneer missionary, who left a big influence on the frame work of Korean modern architecture in the transitional times.

80년대 초 GIS의 개념이 국내에 도입된 후, 1988년 대구광역시를 필두로 지자체의 GIS 구축이 시작되어 국가에서는 GIS 구축의 체계적인 관리의 필요성에 따라 1995년 제1차 국가GIS 기본계획을 수립하고, 2000년 ‘국가지리정보체계의 구축 및 활용 등에 관한 법률’을 제정, 공포하여 각 지자체의 실정에 맞는 GIS 기본계획을 수립하도록 유도하고 있다. 그러나, 바람직한 지자체 GIS 기본계획 작성의 표준이 제시되지 않아 지자체 GIS 기본계획이 개인의 안목이나 타 지자체의 내용을 참조로 만들어져 형식적이고 획일적인 결과물이 산출되고 있다. 그리하여 기존에 수립된 지자체 GIS 기본계획이 일부의 지자체를 제외하고는 해당 지자체의 GIS 구축 사업에 활용되지 못하고 책장속의 책으로 존재하고 있다. 따라서, 본 논문의 목적은 지자체 GIS 기본계획 표준안을 제시하여 향후 해당 지자체에서 GIS 기본계획을 수립할 때, 구성적인 측면의 틀을 제공하여 일정수준을 만족할 수 있는 지자체 GIS 기본계획의 수립을 지원하고자 한다. 지자체 GIS 기본계획 표준(안)을 도출하기 위해서 정보화전략계획과 해외 관련 연구, 국가GIS 기본계획의 검토를 통하여 지자체 GIS 기본계획의 구성요소를 도출하고, 기존지자체 GIS 기본계획의 목차를 중심으로 분석하여, 문제점을 도출하고, 그에 따른 시사점을 제시하여 지자체 GIS 기본계획 표준(안)의 기반이 되도록 하였다. 제안된 지자체 GIS 기본계획 표준(안)은 향후 각 지자체의 활용가치가 높은 GIS 기본 계획의 수립에 도움이 될 수 있도록 하며, 나아가서는 수립된 지자체 GIS 기본계획이 지자체의 성공적인 GIS 구축을 유도하는 가이드의 역할을 수행할 것으로 기대된다.가 있다. 본 연구의 결과를 통해 지방자치단체 GIS 기본계획에 있어 조직 측면의 장기적 비전의 제시가 가능하며 이를 통해 보다 성숙된 GIS 사업의 추진과 효율적인 시스템의 운영이 가능할 것이다.. 이상의 결과를 종합해볼 때, ${\beta}$-glucan은 고용량일 때 직접적으로 또는 $IFN-{\gamma}$ 존재시에는 저용량에서도 복강 큰 포식세로를 활성화시킬 뿐 아니라, 탐식효율도 높임으로써 면역기능을 증진 시키는 것으로 나타났고, 그 효과는 crude ${\beta}$-glucan의 추출조건에 따라 달라지는 것을 알 수 있었다.eveloped.

This is an analytical study on Munheongak (文獻閣) and it's catalogue. The major objective of the study is to get a recognition of Munheongak under the culture of Sukjong (肅宗) period in Korean library history. Most of early studies made on such a category have been concentrated on Jiphyunjeon (集賢殿), Hongmungwan (弘文館), Kyujanggak(奎章閣) and their backgrounds. In this study, the author has invest gated Kungwolji (宮闕志), Munheongakseomg (文獻閣書目) and other materials related to this subject. The findings of the study can be summarized as follows: 1. Munheongak was established by king Sukjong in the 26th year of his reign. According to some records of Kungkwolji, the reason of establishment of the library was to arrange the collection in the Sango (相庫) consisted of various kinds of materials. In case of books, most of them turned out to be Korean books. 2. Munheongak was sited to the estern side of Kyunghyundang (景賢堂), which was located on the Kyungdeokgung (慶德宮). After Youngjo (英祖) the place was called Kyungheuigung (慶熙宮) so as to avoid the name of the precedent king. But these days, both the buildings are not to be found. 3. After its establishment, the library could not play the role as a library because of the then political situation and sectionalism. During the period of the revival of the learning from Youngjo till Jeongjo(正祖) the function of the library was in a stagnant state. Kyujanggak played the part in its place. 4. Referring to the collection management, the Munheongakseomog is equipped with 101 titles, 2,525 volumes, which are arranged by means of the traditional Chinese classification system. 5. The classification scheme is based on the traditional Chinese classification system which might divide all subjects into four categories such as: Confucian classics division, Historical documents division, Master's division, and Collection of literature division. Some illustrations reveal that the classification system was directly influenced by Seogoseomg (書庫書目) : the influence reflected in the classes for the translated literature and writings, poems, genealogy about kings, etc. But some subdivisions such as a class of Annals, Historical Epcerpts were omitted in the classification scheme, which did not strike the balance in the system in terms of the present theory of classification. Most of bibliographical descriptions were also influenced by Seogoseomog but some elements were partly omitted. 6. The special feature of the collection building is the absence of books in Collection of literature division except only three kinds of books in examining the Munheongakseomog. Since this is rather a comprehensive study for such aspects as historical backround, catalogue, and cultural environment of Munheongak and its related record, it is advised that further and additional research should be made.

The designers pursue the thoughtful and wide thinking through the accumulation of knowledge and cultivation of insights for making use of high-level design philosophy and language. The purpose of this study is to investigate characteristics of concept figuration types based on designer's 'memory' in landscape design. The results of this study are as follows. First, the design idea starts to be based on the language and image memory of the designer. The figuration types are composed of the verbal and visual view which are representative communication means. Second, the verbal concept figuration of landscape design consists of two types. The symbolic language of the title as a design theme can be a 'phrase', and it should have a hierarchial balance between the master and the sub. 'Descriptive shape of conceptual scenario' is a text that expresses the concept narratively in order that the reader virtually experiences designed landscapes. Third, visual concept figuration of landscape design is divided into three types. 'Simple visualization of a diagram' is easily embodied through a simple graphic using symbols, comments, images and key words. 'Concept sketch and shape of core idea' is useful to grasp the core of the idea such as physical element, form attribute of space and spatial relation at the initial phase of the concept. 'A collage and montage that create a new shape with a combination of images' are a collection of materials and images that provide a new perspective. These are tools to depict them in a compressed way after recording landscapes phenomenon.
