Objectives : The purpose of this study is to understand the anatomical basis of the facial muscles and to apply this knowledge on the clinical practice of facial acupuncture. Methods : We searched both contemporary and the latest literatures on the practical application of facial muscle anatomy on Facial Acupuncture. Conclusions : Facial Acupuncture improves skin tone, texture and wrinkling by assisting the circulation of Ki. It stimulates the facial muscles directly to undo the stagnation of the meridians. To practice Facial Acupuncture, thorough understanding of facial anatomy is required. In this study the muscles of the head and neck, appropriate depth and angle of acupuncture needle, etc. were reviewed. The upper facial muscles including frontalis, procerus, corrugator supercilii and orbicularis oculi, the mid facial muscles including auricularis, nasalis, levator labii superioris, zygomaticus and so on, and the lower facial muscles including orbicularis oris, depressor labii inferioris, depressor anguli oris, mentalis and platysma etc. were reviewed in this study. For safer and more effective use of Facial Acupuncture, further study on the objective outcome of the technique should be done.

This study is made on the royal lady's dress In late Joseon dynasty according to the King Heon-jong and Lady Kyung-bin's Wedding Diary in the year of Jung-mi(1847) and summarised as follows: Girls' full dress was a set of a red skirt, a violet undo. jacket, and a light yellow jacket and a green Gyeon-ma-gi(a kind of top jacket) with he. hair Saeng-meo-ri hanging Do-tu-rak-daeng-gi(a kind of hair ribbon). At the big ceremony, girls wore a green Dang-ui instead of Gyeon-ma-gi. A girl picked up as a royal concubine wore a green Won-sam, which was decorated with gilt letters meaning longevity, patched emblems of gilt letter meaning longevity on the breast and on the back, belted with Bong-dae(a red sash with gilt phoenexes), like a princess's full dress. At the Kyung-bin's installation of Crown Princess and her first greeting ceremony with royal elders, she wore a green Won-sam as a formal dress, which had an embroidered emblem of phoenix, the belt with crystal ornaments, Pae-ok(佩玉), Kyu(圭) of blue jade, Shou(綬) with an phoenix. At a Dong-wrae-yun(drinking ceremony after bride and bridegroom's bowing to each other), she wore the embroidered red Jang-sam as a formal dress. Kyung-bin wore a purple Won-sam with Bong-dae as a full dress for a royal feast. According to the occasions, the same dress was differentiated with ornaments and rotors. Ji-keum-bal was an attire for ordinary ceremony. The attire was equipped with a woven gold green Dang-ui with an emblem of phoenix, a blue gilt underskirt and a red gilt overskirt. No-ui was worn as outdoor clothes. Jang-sam was worn by various classes, so it was differentiated with materials and names according to her class.

This study is about single-layered $Chog{\breve{a}}ri$ excavated from SongHyosang(宋效商, 1430-1490, SHS hereafter), SongHeeJong(宋喜從, the late 1500s, SHJ hereafter) tombs. There are 7 single-layered $Chog{\breve{a}}ris$ for men. We focus on comparison of their design and sowing method. 1. Design: Investigating collar, $Chog{\breve{a}}ris$ from SHS have MokpanGit and $Chog{\breve{a}}ris$ from SHJ have KalGit. KalGit has been seen from SHJ to 17th, 18th and 19th centuries. After the late 1500s, there is no MokpanGit single-laTered $Chog{\breve{a}}ri$ for men. Side panel under arm has various shapes(triangle, trapezoid, triangle+trapezoid) in 15th century. After the late 1500s, It changes into no side panel. Two $Chog{\breve{a}}ris$ with no side panel from SHJ reveals that the late 1500s is a period of transition. 2. Sewing method: First, researching lengthwise grainline of the fly, the left fly has lengthwise grainline outside In four, inside in three. The right fly has lengthwise grainline outside in just one, the others have lengthwise grainline inside. Compared with today's way, there is a great difference, but in those times there isn't an established rule. This is true of side panel under arm. The sewing method are backstitch, running stitch, and hemming. Researching the construction method of seam, in putting two selvages together, open seam and plain seam are used. In putting selvage and bias, bias and bias together, flat felled seam and french seam are used. This study shows that single-layered $Chog{\breve{a}}ri$ far men from 15C. to 16C. has changes of design such as collar(Git) and side panel undo. arm. But there is little change in sewing method.

The usefulness of single, random measurements of serum FSH and LH in the diagnosis of primary amenorrhea by radioimmunoassay was investigated. The 16 patients were divided into 3 groups by the level of serum FSH and LH. The first group with increased level of serum FSH and LH is five patients, all of these are related to the acquired or congenital abnormality of the ovary. Further studies indicated include buccal smear, chromosome analysis, gynecography and laparosocopy. The second group with normal serum FSH and LH is nine patients, four patients of these are related to the developmental anomaly of the Mullerian duct and five patients are undo etermined origin. Further studies indicated include laparoscopy and gynecography. The third group with decreased serum FSH and normal or decreased serum LH is two patients, one of these is related to the pituitary function, isolated FSH deficiency, the other is undetermined origin. Further studies indicated include the pituitary function test, LH-RH stimulation test, skull radiography. Determination of serum FSH and LH levels does not permit a specific etiologic diagnosis of primary amenorrhea. However the serum levels of FSH and LH can be used to differentiate the principal area of the investigation and can be of assistance in choosing more specific testing procedures.

현재까지 하천의 흐름, 유사이동, 수질해석을 위해서는 외국에서 개발된 소프트웨어를 주로 사용해 오고 있었다. 학술 분야에서는 국내의 모형들이 연구되어졌지만 그에 따른 GUI나 가시화 시스템에 대한 실용화는 거의 이루어지지 못하였다. 본 연구에서는 범용 2차원 하천 흐름, 수질, 유사이동 해석을 위한 GUI 및 가시화 시스템(이하 RAMS, River Analysis and Modeling System)을 개발하여, 하상변동 및 오염물 이송확산에 미치는 수리학적 영향을 규명할 수 있도록 하였다. RAMS는 크게 mesh generator, 해석 모형의 입력 GUI 모듈, 입출력 파일 생성 모듈, 그리고 모의 결과의 가시화 시스템 등으로 이루어져 있다. Mesh generator는 지형자료(이미지 또는 DXF 파일)를 백그라운드 이미지로 가져올 수 있으며, 삼각형 노드와 사각형 노드를 지원한다. 또한 thin triangle들을 제거하는 기능, 선택된 요소(elements)를 제거하는 기능, triangle들을 서로 병합하여 사각형 요소를 만드는 기능, mesh의 renumbering 기능 등을 구현하였다. 특히 사용자가 잘못 생성한 요소들을 바로 이전 상태로 환원하는 undo/redo 기능을 구현하여 능률적인 mesh 생성이 가능하다. 해석 모형의 입력 GUI 모듈에는 각 해석 모형(흐름, 수질, 유사이동)에 특화된 GUI를 설계하여 사용자는 보다 친숙한 환경에서 편리하게 자료를 입력할 수 있다. 입출력 파일 생성 모듈에서는 사용자가 GUI를 통해 입력한 자료를 파일로 변환하여 즉각적으로 모의를 수행하며, 그 출력 파일을 읽어 모의 결과를 자동적으로 가시화한다. 모의 결과의 가시화 시스템에서는 수많은 모의 결과를 체계화하여 등고선 및 화살표 등으로 표현하며, time step 별 결과를 바로 확인할 수 있다. 또한 애니메이션 기능을 구현하여 사용자가 원하는 구간의 time step에서의 모의 결과를 연속적으로 볼 수 있으며, 이 애니메이션을 AVI 파일로 변환하여 다른 동영상 프로그램에서도 재생할 수 있다. 본 연구에서 개발한 RAMS를 이용하여 하천 설계 시 그 공학적 근거를 제시하고, 국내 실정에 맞는 국산 소프트웨어를 제공함으로써 하천의 흐름, 수질, 유사이동 해석에 의한 하천의 수리학적 거동을 보다 편리하고 정확하게 모의할 수 있을 것으로 기대된다.

Triplet(FOF or OFO) injectors are commonly applied to liquid rockets which use LOX and hydrocarbon propellants. The FOF type injector has been known to have an advantage for the although to show lower combustion performance as compared by the OFO type. However, a large disparity between oxidizer and fuel orifice diameters of the FOF type injector may reduce both the combustion efficiency and stability so that as FOOF split triplet injector which splits a single oxidizer orifice into double orifices was designed. In the present study, spray characteristics of the FOOF injector were investigated and compared with those of the FOF injector undo. cold flow conditions. Mass distributions of oxidizer and fuel for both injectors were measured by using a PLLIF (Planar Liquid Laser Induced Fluorescence)technique, and each drop size was also measured by using an instantaneous photographic method. From the experimental results, we found out that FOOF shows more stable mixing efficiencies than the FOF. As for the drop size of both oxidizer and fuel, there was not a large difference between two injector types.

The genus Dendronephthya, generally known as soft corals, is reported as an abundant and variable taxon. They mostly distribute in warmer waters of the Undo-Pacific Ocean region including Korea. In spite of their abundance and ecological importance as habitats of marine organisms, there are difficulties in the study of their identification and systematics because they have morphological variabilities and limited taxonomec characters. To resolve the problems, we attempted to elucidate the genetic relationships in the genus Dendronephthya by using random amplified polymorphic DNA (RAPD) analysis. This study was based on eight dendronephthian species and one Alcyoniidae species, Alcyonium gracillimum, as an outgroup. The results from all analysis suggest that they could be classified into four groups by the growth form and the anthocodial grades as follows: the first one,D. putteri and D. suensoni with the divaricate form and VI grade; the second one,D. sp.1 and D. sp.2 with the divaricate form and III or IV grade; the third one, D. gigantea and D. aurea being closer than D. spinifera with the glomerate form and III grade; the last one, D. castanea related to D. gigantea rather than D. putteri with the umbellate form and IV grade. Moreover, the divaricate form was separated from the group of the glomerate and umbellate form. At the intraspecies level, the types of the D. castanea, D. gigantea and D. spinifera were separated depending on the feature of spicules in the polyp head, and the coloration could not influence genetic variation. From this study, we can confirm that their morphological characters are compatible with the genetic variation, also RAPD analysis is a very useful method for resolving the systematic relationships of den-deonephthians.

The purpose of this study was to develope the transgenic cattle expressing hFSH into the urine using the nuclear transfer. To produce the interest gene in urine, the specific vector was ligated with hFSH gene undo. maUII promoter. The fetal fibroblast cells (KbFF) were isolated from a 45-day male fetus. The hFSH gene was co-transfected with pcDNA3 (neo) vector to KbFF cells by electroporation. The gene-transfected cells were cultured with G-418 selection medium for 2 weeks. Selected colonies were confirmed by PCR. For nuclear transfer, enucleated bovine oocytes were transferred with hFSH transfected or nontransfected fetal fibroblasts. The cleavage and blastocyst formation rates were significantly lower (p<0.05) in cloned embryos transfected with hFSH gene (68.7% and 15.7%) than in those non-transfected (67.6% and 24.5 %), respectively. Apoptosis analysis showed no difference between hFSH transfected and non-transfected blastocysts (p>0.05). The blastocysts were transfected to 77 (control 24, hFSH 53) recipient cows. Two calves were born (1.9%) following transfer with NT embryos transfected with hFSH gene, but they were confirmed not to be transgenic calves. This result shows that the hFSH colonies were mixed with transfected and non transfected cells. Further research will be needed for selection and establishment of gene transfected cells.

To study the characteristics of organic and nutrient removal by Bacillus species at high COD concentration of influent, three lab-scale batch reactors(R1, R2, R3), each of which has different substrate composition, were operated. More than 95% of $NH_4^+$-N and $COD_{cr}$, concentrations were removed under an aerobic condition, and their removal efficiencies were found to be 22.6 and 90.5%(R1), 23.9 and 65.8%(R2), 30.2 and 86.4%(R3), respectively. The removal efficiency of $NH_4^+$-N was high when an enough amount of $NO_3^{-}$-N was supplied, and that of $COD_{cr}$. was low when a high concentration of initial $NO_2^{-}$-N was added. The amount of carbon utilized in denitrification was a little. In all reactors,$NO_3^{-}$-N was removed under an anoxic condition, but in the R3 reactor, 10% of $NO_3^{-}$-N could be removed even undo, an aerobic condition. The removal efficiencies of TN and TP were 41.8 and 49.5%(R1), 40.1 and 35.8%(R2), 47.0 and 57.6%(R3), respectively. Alkalinities destructed under an aerobic condition for each reactor were 4.96, 5.41 and 3.93 mg/L (as $CaCO_3$) per each gram of $NH_4^+$-N oxidized, respectively, while 3.06, 3.17 and 2.60 mg/L (as $CaCO_3$) of alkalinities were produced for each gram of ,$NO_3^{-}$-N reduced to $N_2$. The SOUR were found to be 38.5, 52.7 and 42.0 mg $O_2$/g MLSS/hr, which indicated that Bacillus sp. had a higher cell activity than activated sludge. The OLR and sludge production were estimated to be 0.69 and 0.28(Rl), 0.77 and 0.20(R2), 0.61 kg COD/$m^3$/day and 0.25 kg MLSS/kg COD(R3), respectively. From the N-balance, the highest percentage(40.9%) of nitrogen lost to $N_2$ was obtained in the R3 reactor. From all the results, the possibility of aerobic denitrification Bacillus sp. has been shown and the B3 process seemed to have two advantages: a little amount of carbon was required in denitrification and not much amount of alkalinity was destructed under an aerobic condition.
