The purpose of this study was to comprehend the cognition of Korean tradition and the required basic educational contents among interior architects. The survey had been made 277 designers and the major findings of this study are as follows. First. It is revealed that only a half of interior architect have been taught about Korean tradition in university and their level of knowledge is entry level. Therefore it is found that the education in university on the Korean tradition was not sufficient enough Second, it is believed that one ideal way of expressing Korean tradition is re-interpreting traditional motive with modern views and another way is to express abstractly about Korean traditional space arrangement, composition and space concept. It is found that substantial knowledge and information is required to express Korean tradition effectively. Third. it is found that a lot of interior architect has faced difficulties in carrying out projects because of not having sufficient knowledge related to Korean tradition. Therefore it is recommended to educate basic theory about Korean tradition first and then reinforce the program by including field trip In university curriculum. Fourth. it is necessary to re-educate to current Interior architect because of lacking knowledge about Korean tradition. The recommended area in priority order is traditional Interior space, traditional architecture, traditional color, traditional pattern and traditional furniture

In the course of this research, we developed FRIS(Food Replica Information System), which calculates calories and nutrient values of foods in a very simple and interesting manner, and experienced of application to some communities. We expect that individuals will have opportunities to raise their consciousness of food, nutrients, and healthy living by participating in FRIS. 154 kinds of commonly consumed Korean foods were selected and one serving sized food replicas, having the same shapes, size, and color as the real foods, were constructed with attached bar code labels. An application program with food replicas and bar code was also developed in order to provide information on calories and nutrient values for people's meals or selected foods based on survey results of housewives' requirements related to foods and nutrients. FRIS should be a basic tool in nutrition education and consultation. Its applicability would vary according to the nutritionist's flexibility and contents of developed application programs. Technical stability should be strengthened and more useful contents of application prograln be added to spread the use of the system. Additionally, in future research, more delicate models should be developed and an analytical method should be applied to examine the effects of FRIS to individual behavioral changes in their eating habits.

Objectives : The aim of this study was to determine whether children with Tourette disorder (TD) have functional impairment and executive dysfunction in comparison to children with attention-deficit hyperactivity disorder (ADHD) and non-affected controls. Methods : From January 2006 to December 2013, 45 children and adolescents with TD and 50 children and adolescents with ADHD diagnosed at the Soonchunhyang University Bucheon Hospital and 50 non-affected controls were enrolled in this study. Functional impairment of the subjects was assessed using the Child and Adolescents Functioning Impairment Scale (CAFIS), parent and teacher versions. In addition, neuropsychological tests including Stroop color-word Test, Finger windows Test (FWT), and Digit span were administered. Outcomes were compared across the TD, ADHD, and non-affected controls. Results : No difference in CAFIS-parent and CAFIS-teacher results was observed between children with TD and non-affected controls, whereas, children with ADHD showed more impairments relative to non-affected controls in the CAFIS-parent. According to the Stroop color-word Test, FWT, and Digit span, executive function in children with TD did not differ from non-affected controls. Children with ADHD had poorer performance in measures of the Stroop color-word Test compared to children with TD. Conclusion : Children and adolescents with TD but not ADHD were not significantly different from non-affected controls on most measures of functional impairment and executive function. These findings suggest that an education program and intervention for children with TD would be important to reducing the stigma of TD.

Ultrasonography is non-invasive and can give useful clues in the diagnosis of cervical lymphadenopathy, However, differential diagnosis is difficult in some situations even combined with color Doppler imaging. The present study was conducted to evaluate the clinical value of real time elastography in patients with unexplained cervical lymphadenopathy using a quantitative method. From May 2011 to February 2012, 39 enlarged lymph nodes from 39 patients with unexplained cervical lymphadenopathy were assessed. All the patients were examined by both B-mode ultrasound, color Doppler flow imaging and elastography. The method of analyzing elasto-graphic data was the calculation of the 10 parametres ("mean", "sd", "area%", "com", "kur", "ske", "con", "ent", "idm", "asm") offered by the software integrated into the Hitachi system. The findings were then correlated with the definitive tissue diagnosis obtained by lymph node dissection or biopsy. Final histology revealed 10 cases of metastatic lymph nodes, 11 cases of lymphoma, 12 cases of tuberculosis and 6 cases of nonspecific lymphadenitis. The significant distinguishing features for conventional ultrasound were the maximum short diameter (p=0.007) and absent of echogenic hilum (p=0.0293). The diagnostic accuracy was 43.6% (17/39 cases) and there were 17 patients with equivocal diagnosis. For elastography, "mean" (p=0.003), "area%" (p=0.009), "kurt" (p=0.0291), "skew" (p=0.014) and "cont" (p=0.012) demonstrated significant differences between groups. With 9 of the 17 patients with previous equivocal diagnoses (52.9%) definite and correct diagnoses could be obtained. The diagnostic accuracy for conventional ultrasound combined elastography was 69.2% (27/39 cases). There were differences in the diagnostic sensitivity of the two methods (p=0.0224). Ultrasound combined with elastography demonstrated higher rates of conclusive and accurate diagnoses in patients with unexplained cervical lymphadenopathy than conventional ultrasound. The quantitative program showed good correlation with the pathology of different lymph node diseases.

Design and syntheses of four red phosphorescent heteroleptic cationic iridium(III) complexes containing two substituted phenylquinoxaline (pqx) or benzo[b]thiophen-2-yl-pyridin (btp) main ligands and one 2,2'-biimidazole (H2biim) ancillary ligand are reported: [$(pqx)_2$Ir(biim)]Cl (1), [$(dmpqx)_2$Ir(biim)]Cl (2), [$(dfpqx)_2$Ir(biim)]Cl (3), [$(btp)_2$Ir(biim)]Cl (4). Complex 1 showed a distorted octahedral geometry around the iridium(III) metal ion with cis metallated carbons and trans nitrogen atoms. The absorption, emission and electrochemical properties were systematically evaluated. The complexes exhibited red phosphorescence in the spectral range of 580 to 620 nm with high quantum efficiencies of 0.58 - 0.78 in both solution and solid-state at room temperature depending on the cyclometalated main ligands. The cyclic voltammetry of the complexes (1-3) showed a metal-centered irreversible oxidation in the range of 1.40 to 1.90 V as well as two quasi reversible reduction waves from -1.15 to -1.45 V attributed to the sequential addition of two electrons to the more electron accepting heterocyclic portion of two distinctive cyclometalated main ligands, whereas complex 4 showed a reversible oxidation potential at 1.24 V and irreversible reduction waves at -1.80 V.

Three novel phosphorescent 2-phenylpyridine-based iridium(III) complexes, $[(ppy)_2Ir(P\^{}N)]PF6\;(1),\;[(dfppy)_2Ir(P\^{}N)]PF_6$ (2), and $[(dfmppy)_2 Ir(P\^{}N)]PF6$ (3), where $P\^{}N$ = 2-[(diphenylphosphino)methyl]pyridine (dppmp), were synthesized and characterized. The absorption, photoluminescence, cyclic voltammetry and thermal stability of the complexes were investigated. The complexes showed bright blue luminescences at wavelengths of 448 $\sim$ 500 nm at room temperature in $CHCl_3$ and revealed that the $\pi$-acceptor ability of the phosphorous atom in the ancillary dppmp ligand plays an important role in tuning emission color resulting in a blue-shift emission. The single crystal structure of $[(dfmppy))_2Ir(P\^N)]PF_6$ was determined using X-ray crystallography. The iridium metal center adopts a distorted octahedral structure coordinated to two dfmppy and one dppmp ligand, showing cis C-C and trans N-N chelate dispositions. There is a $\pi-\pi$ overlap between π electrons delocalized in the difluorophenyl rings.

As part of the SPVS (Short-Period Variability Survey) which is a wide-field $(90'{\times}60')$ photometric monitering program at Bohyunsan Optical Astronomy (BOAO), we performed V band time-series CCD photometric observations ofthe young open cluster NGC 129 for 11 nights between October 12, 2004 and November 3, 2005 using the 155mm refractor equipped with $3K{\times}2K$ CCD camera. From the observation we obtained 2400 V band CCD frames and color-magnitude diagram of the cluster. To transform instrumental magnitude to standard magnitude, we applied ensemble normalization technique to all observed time-series data. After the photometric reduction process, we examined variations of 9537 stars. As a result, sixty six of the new variable stars were discovered. To determine the periods of the sevariables, we used DFT(Discrete Fourier Transform) and phase-matching technique. According to light curve shape, period, amplitude and the position on a C-M diagram, we classified these variables as 9 SPB type, 9 ${\delta}$ Scuti type, 29 eclipsing, 17 long term variables. However, two of them were not classified. From this study, we learned that small telescopes could be a very useful tool to observe variable stars in the open cluster in survey program.

This study was carried out to provide the improvable way of foodservice management to dietitian in the elementary schools. For this purpose the serving pattern of food, menu planning, nutrition education, leftover management and difficulties in foodservice were investigated. The survey was conducted through questionnaires, which were collected from 249 dietitions randomly selected in Taejon and Chung Nam. Data were analyzed by SAS program. The main results of this study are as follows. The children in Taejon took foods in the class room(65.7%) and those in Chung Nam in the dinning hall(89.9%)(p<0.01). In menu planning the balance of nutrition(42.6%) was mainly considered and then food preference(19.7%), variety of menus(16.1%), food cost(16.1%), composition of food color, taste and texture(3.2%), skills of food making(1.6%) and the number of students(0.8%). They referred cooking magazines(47.7%), the previous menu(42.2%), children's opinion(7.2%) for planning menu. The insufficiency of implements and devices for food(24.1%) and lack of season's food(20.4%) were indicated as difficulties in their job. 34.5% of dietitians used a standard menu, 79.5% investigated food preference of children, 74.3% evaluated taste of foods before serving, and 80.7% regularly checked leftover. The major reason for leftover was careless of the teacher in charge in Taejon and bad taste of foods nutrition in Chung Nam(p<0.001). 98.5% of them answered that they had the responsibility for nutrition education in elementary school. They had a hard time in relationship with the staffs in school(40.6%) and employees for food(39.8%), and lack of market information(38.2%). To efficiency of dietitian's work can be enhanced by reflecting the results of children's food preference and leftover, by using standard cooking method and proper cooking utensil, and by performing nutrition education for children by themselves.

Our country has been consuming a huge amount of energy in the course of industrialization and its demand is expected to increase enormously in the future. However, the deposits of energy resources are so limited that the settlement of energy problem comes up the essential subject. To solve the energy problem, it is requested that new resources to gain energy stably should be developed and also energy should be economized and used effectively. The effective use of energy and an the wisdom of economy in energy are requested to everybody and these things should be habitualized from very young age through education. Nevertheless, almost every school in our country hasn’t been concerned about energy education. Even though they have a concern, they are very short of the energy education materials and the quality of the materials is not so good. Therefore it is very meaningful to the settlement of energy problem of the country to make the students who will lead our country to make the students who will lead our country in the future realize the seriousness of energy problem and to provide them the necessary knowledge and methods to solve this problem so that they practice those things in everyday life. Having these necessities, this research, supported by The Korea Energy Management Corporation(KEMCO), was performed for 8 months from April 17, 1994 to December 17, 1994. Many peoples participated in this study such as 30 staffs of researchers and authors, 5 staffs of photographers and illustrators, and 3 VCR program producers developing an energy education material set for middle school students that includes a printed material for student, a diskette for computer simulation, a teacher's guidebook, VCR material and its guidebook. The following main development direction was established : First, the material for student should be consisted of units that let students know the seriousness of energy problem. Second, the focus should be put on the necessary method and practice to economize energy actually in real life based on the basic knowledge learned in elementary school. Third, material for student should be consisted of modules to be student activity-oriented teaching-learning rather than lecture-oriented one. The activity, to maximize student's interests, should be presented in various forms such as experiments, investigation, play, data interpretation, computer simulation, visits, expression and appreciation, etc. To develop the energy education materials for middle school students, a research plan was made first. After literature review about domestic and foreign energy education materials, several research trips home and abroad, and discussion meetings, the basic theory of energy education such as the principle, objective, contents, teaching-learning method, and evaluation method was established. Material for student was developed through the following procedures : The activities in the existing energy education materials were analysed and were divided into four categories related to energy using places of home, school, community, and country, and which were again divided into three categories related to time of past, present, and future, Considering these division, nine modules which are structure units of material for student were chosen, Each module comprises 2-4 activities. Totally 31 activities were designed in this way. The syllabi were made out for each activity and writing was asked for to experts related to each activity after several discussions and revision. To complement the draft, another several discussions and revision were also made on it and then pictures and illustrations were asked for. All these procedures complete the material for student, titled ; Energy Inquiry of Middle School Students', which totals 129 pages and is all in color. As the manuscript of material for student was fixed, writing for teacher's guidebook was asked for to the same writers. The draft of teacher's guidebook was also complemented through the several concentrated works and discussions. Teacher's guidebook focused on the teaching-learning principle and methods of energy education and on the concrete instruction cases for effective instruction of material for student. It is organized with two parts : the one is 'general outline' which introduces theoretical contents and the other is 'details' which are practically helpful to teaching-learning. It is totally 131 pages including both 'general outline' and 'details'. The VCR material and its guidebook consist of contents that cultivate the good attitude trying to economize energy and raise student's interests with a purpose of strong motivation to recognize the necessity of economy and practice it. After establishing development direction of VCR material through discussion meetings and research trips, its script was made by relevant experts. Then the script was also reviewed two times. The drafted VCR material made by a video material developing expert was examined and modified by previews twice. After completion of VCR material, the VCR guidebook was made. All these procedures led to the development of VCR material which runs 20 minutes in VHS type. The VCR guidebook shows a production purpose of the program, structure of contents, evaluation methods, and contents of the program in detail to give help to instructors when they use this VCR material, When these energy education materials are used, it is desirable that the VCR material should be presented first to induce student's motive, and then material for student is introduced Since the material for student is composed of activity-oriented modules and each module is independent one another in general, and each activity is, too. the necessary module or activity can be chosen and utilized in any order according to school or class conditions. This energy education materials will contribute to the development of student's ability to solve energy problem in everyday life and teacher's ability to teach the fundamental knowledge and method in solving energy problem.
