Rainbow trout, Oncorhynchus mykiss, were cultured with different levels of carotenoids in odor to investigate the feeding effect of ascidian tunic extracts on the liver fatty acid compositions of them. Dominant monoenoic fatty acids of the ascidian tunic extracts were 16:1n-7($5.9\%$), 18:1n-9($21.9\%$), and 18:1n-7($3.5\%$) and polyenoic fatty acids of them were linoleic(18:2n-6, $14.2\%$), eicosapentaenoic(20:5n-3, $3.5\%$), and docosahexaenoic acid(22:6n-3, $8.3\%$). The compositions of fatty acid in the liver lipids were affected by the tunic extract levels during the feeding. The percentage of monoenoic acids in extract diets was decreased, and that of n-3PUFA was increased during feeding 2 weeks. But the n-3PUFA contents were decreased in 4 weeks. The 20:4n-6 content in rainbow trout fed extract diet was higher than that in the control and pink diet groups. The rainbow trout fed with ascidian tunic extracts showed an increase of essential fatty acids in the fish tissue, compared to the control or pink diet feeding groups.

The multifunctional compound such as conjugated linoleic acid (CLA) was used to producing of functional larval rockfish. Artemia, livefoods for larval fish, enriched with highly unsaturated fatty acids (HUFA) and CLA ($0.5\%$, $1.0\%$, $2.5\%$ and $5.5\%$ group) was fed to larval rockfish. Artemia, enriched with $2.5\~5.0\%$ of CLA, negatively affects the quality of larval rockfish. But $1.0\%$ CLA fed group shown to good specific growth rate, feed efficiency, n-3/n-6 PUFA ratio, DHA/EPA ratio and hematology results. The CLA deposited in muscle lipids of larval rockfish was reached 6.57 to $19.69\%$.

The degrees of retrogradation (DR) for 50% rice flour gels kept at $4^{\circ}C$ and $20^{\circ}C$ for the 6-day storage period at 0.5, 1.0 and 2.0% (w/w, on dry weight basis) levels of lipid additives (sucrose fatty acid ester, SE1670; soybean oil) were measured by ${\alpha}$-amylase-iodine method, differential scanning calorimetry (DSC) and X-ray diffractometry. The DRs were higher in rice flour gels stored at $4^{\circ}C$ than those stored at $20^{\circ}C$. The sucrose fatty acid ester and soybean oil reduced the retrogradation of rice flour gels, but the effect was higher in samples stored for 1 day. The DR decreased more effectively in the addition of SE1670 than that of soybean oil In case of SE1670, the change of enthalpy by DSC showed similar patterns with the degree of retrogradation by ${\alpha}$-amylase method; however, it was not the case for soybean oil. The intensity of peak at $2{\theta}=16.7^{\circ}$ in X-ray diffraction pattern was reduced with lipid additives but it was not clear.

Effect of amylose content on the physical properties of resistant starches (RS) from autoclaved maize starches (with starch:water=1:3.5, at $121^{\circ}C$) which were repeated up to 4 times heating-cooling cycles, were investigated by water uptake, scanning electron microscope (SEM) and differential scanning calorimetry (DSC). Amylose content of waxy maize starch (Amioca), common maize starch (PFP), high amylose starch(Amaizo, Amylomaize VII) were 0%, 29%, 50%, and 72%, respectively. Yield of RS increased as amylose content increased. Water uptake of all kinds of native starch was higher than that of RS, but lower than that of autoclaved starch. By SEM, RS showed some small particles on surface but the size of particles was different with amylose content. Single endothermic transition peak exhibited at $40{\sim}70^{\circ}C$ in autoclaved Amioca and PFP (crystalline melting of amylopectin) and at $132{\sim}169^{\circ}C$ in autoclaved Amaizo and Amylomaize VII(crystalline melting of amylose) by DSC. RS from all kinds of autoclaved starches except Amioca showed single endothermic peak over $155^{\circ}C$ but the enthalpy was not related to amylose content.

This study is designed to delve into the measuring systems of different periods so as to help with more exact representations of cultures of different periods. The basis of the measuring system in china stems from the huangjong (Huangzhong : the yellow bell) of the period of Huangdi, the length of the bell being the width of 90 black millet grains. Do (Du : width) ; 1 bun=the width of one black millet grain, 1 Chon=10 Buns, 1 Chuk=10 Chons, 1 Jang=10 Cheoks, 1 In=10 Jangs. Ryang (Lyang : volume) ; 1 Yak=the weight of 1,200 grains in the yellow bell, 1 Hab=2 Yaks, 1Seung=10 habs, 1 Du=10 Seungs, 1 Gok=10 Dus. Hyung (Hung : weight) ; 12 Jus=the weight of 1 Yak, 1Yang=24 Jus are equal 1 Hab in weight, 1 Geun=16 Ryangs, 1 Jo=30 Geuns, 1 Seo=4 Jo. In the era of Eun (In) it was decided that the 9-chon length of the Yellowbell shall be 1 Cheok. The Cheok of Ju was set at 4/5 of the length of the yellow bell. The Cheok of Ju breaks into Yongjocheok, Joryegicheok, Pogeumcheok. Yongjocheok, arising from Rohbancheok of the Ju period, is part of Gokcheok also used as a measuring tool for wooden works. The Han cheok has the same length as the yellow bell. The Sang Cheok is 4/5 of the length of the yellow bell. The Tang Cheok was originally the same as the Sang cheok but became longer and longer to be the Long cheok (31.3cm). The length-measuring system used in the three-nation era of Korea includes the gijeom cheil (35.52cm), Ju cheok (25.45cm), sunje Cheok (23.5cm), the Long Tang Cehok (29.706 cm), making 10 Bun 1 Chon and 10 Chon 1 Cheok. The volume-measuring system(Seung) was 198.81 ㎤ before 681 BC in the shilla Dynasty and was 596.42 ㎤ after that. In the seventh year of Kng Munjong of the Koryo dynasty the standard measuring system with the Long Tang Cheok as its basis was adopted, and the standard volume-measuring tools were used under the name of Migok, Daesodugok, Mijangdu, (29.706 cm), making 10 Bun 1 Chon and 10 Chon 1 Cheok. The volume-measuring system(Seung) was 198.81㎤ before 681 BC in the shilla dynasty and was 596.42 ㎤ after that. In the seventh year of King Munjong of the Koryo dynasty the standard measuring system with the Long Tang Cheok as its basis was adopted, and the standard volume-measuring tools were used under the name of Migok, Daesodugok, Kijangdu, Habseung and gokseok. The 1 Seung volumes of theses toolas were 596,447,927 and 1053㎤, respectively. were called Migok, Daesodugok, Mijangdu, Habseung and Gokseok, being respectively 596,447,927, 1053 ㎤, respectively. In the Chosun Dynasty the length of the Yeongjocheos was 27.6 cm or 31.220 in the Sejong era, 29.8 from Heonjong through Gojong, and 30.3 cm after the 6th year of King Kwangmu, and the volume of Du(Mal) also changed like 4.121 or 5.964, 5.187, 23.08 $\ell$, and the 1-Jeonjung also changed like 2.66 or bout 4, 3.45, 3.75 in line with the changes of the length system.

Purpose: The Le Fort I osteotomy is a commonly performed maxillary procedure for dentofacial deformity. One of the risks of this procedure is major hemorrhage resulting from injury to the descending palatine artery. So it is very important to know the exact position of the descending platine artery. An increased understanding of the position of this artery can minimize the intra-operative bleeding while allowing extension of the bone cuts to achieve exact positioning maxilla. The aim of this investigation was to study the position of the descending palatine artery as it relates to the Le Fort I osteotomy. Methods and patients: Total 40 patients who underwent Le Fort I osteotomy in SNUDH OMFS were studied in this study. We measured the distance from the pyriform aperture to the descending palatine artery (DPA distance) using a ruler. We investigated the relationship between DPA distance, the distance from A point to the McNamara line on lateral cephalography and the patient's body height. Results: The average distances from the pyriform rim to the descending palatine artery were 35.3 mm on the right (range: $30{\sim}40mm$) and 33.7mm (range: $30{\sim}41mm$) on the left in males. Those in females were 33.4 mm on the right (range: $28{\sim}40mm)$ and 32.8mm (range: $27{\sim}38mm$) on the left. The significances between the distance the DPA distance, the body height and the distance from A point to McNamara line were not found. Conclusion: Injury to the descending palatine artery during Le Fort I osteotomy can be minimized by not extending the osteotomy more than 30 mm posterior to the pyriform aperture in mal, and 27 mm in female.

The purpose of this study is to offer information needed in developing mental health service programs which can help mental patients to improve their self-esteem. For that purpose, the difference and the interrelation between mental patients' characteristics, and their self-esteem, group consciousness and consciousness of right were examined. And also, in practice, I observed 374 patients suffering from mental problem, who live in Busan and in Kyeong Nam province. As the result, the several facts which could be got from this theoretical examination and practical observation are as follows: First, it is shown that what is meaningfully related to mental patients' self-esteem are their educational level, the families' monthly earnings, a feeling of satisfaction to family relationship, the time spending together with their friends, or a feeling of satisfaction to their friends Second, it is appeared that there was a significant interaction between group consciousness of mental patients, and whether they have got married and the time spending together with their friends. Third, it is found out that their feeling of satisfaction to family relationship and the time spending together with their friends have meaningful relation to consciousness of right which mental patients have. Finally, speaking of interaction among self-esteem, group consciousness and consciousness of right, it is understood that self-esteem has significant effect of group consciousness, and that group consciousness has confidential effect on consciousness of right.

Gulbi were processed by salting Yellow corvenia (Pseudosciaena manchurica) with in three ways: the dry salting method with bar salt, the dry salting method with purified salt or with the abdominal brine injection method with purified salt. The half of the sample was dried by the control system of temperature and humidity; the other part was dried by the natural condition. The moisture content of fresh Yellow corvenia muscle and eggs were 76.8%, and 68.2% while those of dried samples decreased to 57.7% and 45.3%, respectively. The total nitrogen content of fresh muscle and eggs were 11.0g% and 7.6g%, respectively (dry weight basis), which decreased slightly during salting and showed no significant changes during drying prosess. The protein nitrogen content of fresh muscle and eggs were 10.2g% and 7.5g%, which decreased during Gulbi processing. On the other hand, the nonprotein nitrogen content of both muscle and eggs increased. The content of free amino acids of fresh muscle and eggs were 508.8mg/100g and 1,110.6mg/100g, which increased to between 5.3 and 2.7 times, respectively after 25 days of drying. The composition patterns of free amino acids in muscle and eggs were similar to each other. The four amino acids - Ala, Glu, Lys and Leu - were most abundant in both fresh and dried samples. These amino acids are known as taste and flavour constituents.

In this paper, we design a UWB / WAS microstrip antenna for wireless local high - speed communication. The substrate of the proposed antenna is FR-4 (er = 4.3) and its size is $30[mm]{\times}30[mm]$. It is designed to have characteristics that can be used in the frequency bands of 3.5 [GHz] and 5.2 [GHz], which are UWB / WAS frequency bands. The simulation was performed using CST Microwave Studio 2014. Simulation results show that the gain is 1.592 [dBi] at 3.5 [GHz] and 2.210 [dBi] at 5.2 [GHz]. The S-parameter also showed a result of less than -10 [dB] (WSWR 2: 1) in the desired frequency band. Microstrip antennas have been miniaturized, high performance, and light weight, and excellent and low cost systems are continuously being developed. In addition, many people use wireless local area network systems used in homes, companies, and public facilities. Since the UWB / WAS technology is proposed according to the development of the system and the demand increase, the antenna that satisfies the above conditions will be designed and the technology applicable to the system will be used more conveniently.
