Objectives : Cervus Elaphus(CE) has been used to medication for ischemic stroke in the Oriental Medicine. So this study was planned to investigate the effects of CE herbal acupuncture therapy(CE-HAT) on the focal ischemia-induced by intraluminal filament insertion in the rats. Materials and methods : The focal ischemia was induced by middle cerebral artery occlusion for 2hours. The groups divided into 6 groups, normal(intachess group), control(no theray group after ischemia-induced), CE-HAT1(Cervus Elaphus-herbal acupuncture therapy group at LR1, HT9 after ischemia-induced), CE-HAT2(Cervus Elaphus-herbal acupuncture therapy group at LU8, KI7 after ischemia-induced), CE-HAT3(Cervus Elaphus-herbal acupuncture therapy group at LR1, HT9, LU8, KI7 after ischemia-induced), CE-HAT4(Cervus Elaphus-herbal acupuncture therapy group at LR1, HT9, HT3, KI10 after ischemia-induced). CE-HAT was carried out during 3 weeks after focal ischemia-induced. Eight-arm radial maze was used for the behavioral task and neuropretective effect of CE-HAT was observed by Cresyl violet, AchE, ChAT-stain. Results : The error rate in the eight-arm radial maze task was significantly decreased in CE-HAT1, CE-HAT2, CE-HAT4 on 3days, CE-HAT4 on 4days, CE-HAT2, CE-HAT4 on 5days, CE-HAT3, CE-HAT4 on 6days. The rate of correct choice was significantly increased in CE-HAT4. The density of neurons in the hippocampal CA1 was significantly increased in CE-HAT1, CE-HAT2, CE-HAT3, CE-HAT4, compared to control group. The density of ChAT in the hippocampal CA1 was significantly increase in CE-HAT4. The density of ChAT in the hippocampal CA1 was significantly increased CE-HAT1. Conrlusions : These results suggest that the Cervus Elaphus-herbal acupuncture therapy could be used as a medication for controlling the stroke induced by deficiency.

The Purpose of this study were to study Retro-hat design. To do these purposees, the focus of theoretical approach was literature research, and hat design was attempted on the basis of the research. The focus of theoretical background was on previous research and fashion-related literature. Photo materials to analyze retro-hat design is Haute-Couture collection in paris from the 1990's to 2004 and some designer's collections. Then Retro hat design is 85 in 1,381 hat photos. The results obtained through this process were as follows. In the hats of Retro, the past style such as an Egyptian wig, a snake-shaped hat in Crete, a Medieval knight hat, Liripipe, Tricorn hat, or Bicorn hat was reinterpreted and expressed. Since 2003, Retro characteristics has became strong and frequent. By designing a hat on the basis of the direction of hat design, this study intended to find out the development direction of hat design.

Acetylation of lysine residues within the aminoterminal domains of the core histones plays a critical role in chromatin assemhly as well as in regulation of gene expression. To study the biochemical function of histone acetylation, we have cloned a cDNA encoding the catalytic subunit of human histone acetyltransferase, Hat1. Analysis of the predicted amino acid sequence of human Hat1 revealed an open reading frame of 419 amino acids with a calculated molecular mass of 49.5 kDa and an isoelectric point of 5.5. The amino acid sequence of human Hat1 is homologous to those of known and putative Hat1 proteins from various species throughout the entire open reading frame. The recombinant human Hat1 protein expressed in bacteria possesses histone H4 acetyltransferase activity in vitro. Both RbAp46 and RbAp48, which participate in various processes of histone metabolism, enhance the histone acetyltransferase activity of the recombinant human Hat1, indicating that they are both able to functionally interact with the human Hat1 in vitro.

This study examined the effects of two kinds of functional sun hats through a head-manikin test and a climatic chamber trial for farm workers in summer. Experiment was composed of four conditions. The first condition was the condition without any hat (Control). The second was the condition with a sun hat on the market (Hat A). The third was the condition with a functional sun hat made of reflective fabric (Hat B). The last was the condition with a functional sun hat having a ventilating structure as well as reflective fabric (Hat C). For the subjects in the climatic chamber trials, 12 healthy males volunteered. Air temperature, relative humidity and globe temperature in the chamber was maintained at $33{\pm}0.5^{\circ}C,\;65{\pm}5%RH\;and\;39{\pm}1^{\circ}C\;(WBGT\;33^{\circ}C)$. Subjects did a simulated red pepper-work (50-min work and 10-min rest, twice repetition) for 120 min. As the result of head-manikin test, the surface temperature on middle of back-neck was the lowest in Hat B of four conditions and the surface temperature on top of head was the lowest in Hat C. As the result of climatic chamber trials, there were apparent differences between with (Hat A, Hat B, Hat C) and without a sun hat (Control). In rectal temperature ($T_{re}$), mean skin temperature ($\={T}_{sk}$), heart rate (HR), total sweat rate (TSR), The physiological heat strain was less in the condition with hats than in the condition without a sun hat. As the increasing rate in Tre, Hat B is the most effective hat for alleviation heat strain. As the subjective responses, Hat B was the most effective hat for thermal comfort even though the difference was not significant. Hat C was less effective than Hat B and the reason might be the increase of weight due to inserting the ventilating structure.

This paper is extended the meaning and period of CONICAL HAT. That is, the race in Central Asia and Western Asia have worn the conical hat before Scytian appeared. One in conical hat puts on the clothes of two-piece style and has the lifestyle. a horse riding and nomadism. Besides the race originate into the Indo-European language family. On the whole the conical hat has relations with the region and is classified into two groups. Scytian and Klin-Yar style. First. the Scytian style of low hat forms the seam of two-piece and is discovered in Southern Russia. Central Asia and East-Northern Asia. Second, the Klin-Yar style of high hat forms the one piece and generally is discovered in Asia Minor and west of Altai. Until now the moaning of the conical hat has focused on the military. However, one in Central Asia and Western Asia is mostly a king. nobility and god. Therefore, in addition to the meaning of military. I estimate that the conical hat may be expressed as the noble status.

조석현상이 뚜렷한 연안에서 항해, 연안 구조물 설계, 해양영토 획정, 침수범람 예보 등을 위하여 여러 조위 기준면들(tidal datums)이 사용된다. 우리나라 수로학 분야와 해안공학 분야에서는 수심을 측량하는 기본 수준면(datum level)으로 약최저저조위(ALLW)를 사용하고, 해안선과 안전수직높이(vertical clearances) 기준면으로는 약최고고조위(AHHW)를 사용하고 있다. 그러나 최근에 미국, 호주, 영국을 포함하여 국제적으로는 최저 천문조위(LAT)와 최고 천문조위(HAT)를 기본 수준면과 안전수직높이의 기준면으로 사용하고 있다. 이 연구에서는 서해안과 남해안 9개 조위 관측소에서 19년(1999-2017년) 동안 1시간 간격으로 관측한 해수면 높이 자료를 '19년 벡터평균 분석', '19년 연속 분석', '1년 연속 분석' 방법으로 각각 1분 간격으로 19년간 예측한 조위로부터 LAT와 HAT를 계산하였다. 이 연구에서는 19년 연속 관측자료의 조석 조화분해와 19년 연속 조석 예측에 모두 적합한 UTide 프로그램을 사용하였다. 각 조위 관측소에서 '19년 벡터평균 분석'과 '19년 연속 분석' 방법으로 각각 계산한 LAT 또는 HAT 값들의 차이는 대부분 ±1 cm 미만으로 큰 차이를 보이지 않았으며, 이 두 방법은 서로 거의 일치하는 결과를 생산하였다. 반면에 각 조위 관측소에서 19년간 연속 관측한 자료를 연별로 19개로 나누어 각각 1년 자료씩 조석 조화분해한 후 각각 19년간 조위를 예측한 '1년 연속 분석' 방법은 서로 크게 다른 19개의 LAT와 HAT 값들을 산출하였으며, 그 19개들의 표준편차는 3~7 cm이었다. '1년 연속 분석' 방법으로 구한 이들 값들은 '19년 연속 분석' 방법으로 산출 값과 비교하면 서해안과 남해안에서 LAT는 -16.4~10.7 cm의 차이를 보였으며, HAT는 -8.2~14.3 cm의 차이를 보였다. 계산된 LAT와 HAT를 ALLW와 AHHW와 정량적으로 비교했을 때, 서해안과 남해안에서 LAT는 ALLW보다 평균적으로 46.2 cm 더 낮았으며, HAT는 AHHW보다 평균적으로 33.6 cm 더 높았다. 이러한 차이에 가장 크게 기여하는 분조는 ALLW와 AHHW 계산에 고려되지 않은 진폭이 비교적 큰 S_a와 N₂ 분조이었다. 또한 천해분조가 강하게 발달한 내만에서는 M₄와 MS₄ 분조가 추가적으로 그 차이에 상당히 기여하였다. LAT와 ALLW 간 차이와 HAT와 AHHW 간 차이가 같지 않은 이유는 ALLW와 AHHW를 계산할 때는 주요 4대 분조의 진폭만을 사용하지만 LAT와 HAT를 계산할 때는 실질적으로 67개 분조의 진폭뿐만 아니라 지각도 사용하기 때문이다.

The spot welded sections of automobiles (hat and double hat shaped sections) absorb most of the energy in a front-end collision. The target of this paper is to analyze the energy absorbing capacity of the structure against the front-end collision, and to obtain useful information for designing stage. Changed the spot welded pitches on the flanges, the hat and double hat shaped section members were tested on the axial collapse loads at various impact velocities. It was expected that para-closed sections would show collapse characteristics which be quite different from those of perfectly closed sections. Hat shaped section members were tested at the impact collapse velocities of 4.72m/sec, 6.54m/sec and 7.1m/sec and double hat shaped section members were tested at the impact collapse velocities of 6.54m/sec, 7.1 m/sec and 7.27m/sec.

This study aims to suggest basic data for the production of hats for aged women. The subjects were 151 females who are 60 years old or above and live in Busan. Their hat-wearing reality was inquired and their head parts were measured, which led to the following conclusion: 1. Results of Hat-Wearing Reality Inquiry 64.9% answered they are unsatisfied with the size system of the available hats at present, implying the necessity for improving the current dimension system. 92.7% responded hat dimensions need to be subdivided, while 97.4% were for the necessity of hat size system. 74.8% expressed their will to buy ordered hats because they can find the hats of right sizes and designs. 2. Results of Head-Part Measurement Experiments According to head-part measurement, head circumference A was 53.26cm, head circumference B 54.19cm, and head circumference C 57.69cm on the average. Cluster analysis revealed three types. Type 1 (24%) with small head length and circumference is the smallest head with a wide upper part. Type 2 (33%) has long head height, short bitragion arc A, and thick head breadth. Type 3 (43%), owing to big head circumference and length as well as high values in vertical items. Considering head circumference B (HCB) and bitragion arc A (BAA), a new hat size system of 3 sizes (HCB: BAA) was chosen: S (52cm: 29cm), M (53-55cm: 30cm), and L (56-57cm: 31cm).
