The Treasure No.165 of Ojukhen is a separate house(別堂) which was still remained as a gentry house in the earliest day. The formative aspects have the important meaning as the history of Korean architecture. Specially the place is famous for Shin, Saim-dang(申師任堂) gave birth to Yulgok(栗谷) Yi, I(李珥). The house was built by one's family of Gangneung Choi clan(江陵崔氏) but Son-in-law inherited the house because there was the practice of inheritance by equal distribution and the mother of Shin, Saim-dang, Yongin Lee clan(龍仁李氏) inherited Gwon, Cheo-kyun(權處均) who was her hrandson under the condition of looking after the tomb. The reason why house name was Ojukhen is that Gwon, Cheo-kyun's another name is Ojukhen. Ojukhen is cultural properties which showed the change of practicing inheritance and ancestral rites. Ojukhen has the special relationship of one's grandson and did not have such of immediate family. This is because there were customs husband had to go to married woman's house and live there during short time. Yongin Lee clan and Shin, Saimdang has lived in the Ojukhen. Yongin Lee clan lived there after marrying. Shin Saimdang also spent a time of living her house after marrying and his son(Yi, I) was born in the place. Yi, I spent their time under Yongin Lee clan and one's mother's parents. Therefore he had a good relationship with his maternal grandmother. This is why his maternal grandmother became a descendant offering sacrifice to his ancestors. The reason why Gwon, Chen-kyun looked after the tomb of Yongin Lee clan was also Gwon, Hwa(權和) became sonin-law who lives with his wife's family. Ojukhen is the showcase of finding the marriage and living manage in the early Joseon Dynasty. The most village of Buk-Pyeong(北坪村) in the Gangneung called by Yi, I's one's mother's parents' home. Since after, the place was changed as the clan village immediate family of Andong Kwang clan(安東權氏) of Gwon, Cheokyun of Chumilgong family(樞密公派). After 17C, there were social historic changings focused on relative group. Ojukhen was the start of changing the clan village. Ojukhen is cultural properties which showed inheritance, relative, marriage in the turning point of Joseon Dynasty.

The red pepper (Capsicum annuum L.) is one of the most important vegetables in traditional Korean food, containing vitamins A, C, and E, polyphenol, and flavonoids. In addition, red peppers have high anti-oxidant ability and are known to be effective in preventing obesity, diabetes, hypertension, digestive disorders, stress, and aging. In this study, we investigated the effects against obesity and diabetes of both fermented and non-fermented red pepper. C57BL/6N mice with induced obesity from an eight-week 45% high fat diet (HFD) were then fed either an HFD or diets containing 2.5% non-fermented red pepper marc (NRM), 1.25% fermented red pepper marc (FRM), or 2.5% FRM for a further eight weeks. An oral glucose tolerance test was performed seven weeks after dietary intake, and body weight, liver, epididymal fat weight, serum insulin level, and HOMA-IR were measured and a lipid content test performed at eight weeks. The results show that the 2.5% FRM diet reduced body and tissue weight, lipid content, serum insulin levels, and HOMA-IR compared to the 2.5% NRM and HFD diets. These results suggest that fermented red pepper is effective against obesity and diabetes. We will use this information as the basic data for the development of health food materials using red pepper.

The phytochemical compounds of Pueraria, a medicinally important leguminous plant, include various isoflavones that have weak estrogenic activity and a potential role in preventing chronic disease, cancer, osteoporosis, and postmenopausal syndrome. However, the major isoflavones are derivatives of puerarin and occur mainly as unabsorbable and biologically inactive glycosides. The bioavailability of the glucosides can be increased by hydrolysis of the sugar moiety using ${\beta}$-glucosidase. In this study, we investigated the antioxidant effects of a Pueraria extract after fermentation by Lactobacillus rhamnosus BHN-LAB 76. The L. rhamnosus BHN-LAB 76 strain was inoculated into Pueraria powder and fermented at $37^{\circ}C$ for 72 hr. The total polyphenol content of the Pueraria extract increased by about 134% and the total flavonoid content increased around 110% after fermentation with L. rhamnosus BHN-LAB 76 when compared to a non-fermented Pueraria extract. Superoxide dismutase-like activities, DPPH radical scavenging, and ABTS radical scavenging increased by approximately 213%, 190%, and 107%, respectively, in the fermented Pueraria extract compared to the non-fermented Pueraria extract. Fermentation of Pueraria extracts with L. rhamnosus BHN-LAB 76 is therefore possible and can effectively increase the antioxidant effects. These results can be applied to the development of improved foods and cosmetic materials.

Saposhnikovia has been used as a traditional medicinal herb in Asia because of the reported anti-inflammatory, anti-allergic rhinitis, pro-whitening, anti-atopy, anti-allergy, and anti-dermatopathy effects of the phytochemical compounds it contains. In this study, we investigated the antioxidant effects of a Saposhnikovia extract after fermentation by Lactobacillus plantarum BHN-LAB 33. Saposhnikovia powder was inoculated with L. plantarum BHN-LAB 33 and fermented at $37^{\circ}C$ for 72 hr. After fermentation, the total polyphenol content of the Saposhnikovia extract increased by about 14%, and the total flavonoid content increased by about 9%. The superoxide dismutase-like activities, DPPH radical scavenging, ABTS radical scavenging, reducing power activity, and tyrosinase inhibition activity also increased after fermentation by approximately 70%, 80%, 45%, 39%, and 44%, respectively. The results confirmed that fermentation of a Saposhnikovia extract by L. plantarum BHN-LAB 33 is an effective way to increase the antioxidant effects of the extract. The bioconversion process investigated in this study may have the potential to produce phytochemical-enriched natural antioxidant agents with high added value from Saposhnikovia matrices. These results can also be applied to the development of improved foods and cosmetic materials.

In this study, we reviewed the preparation process and the main Uimul involved in the procession of Gyeongsang Gamsa Doim in the late Joseon Dynasty. We reviewed the Yeongyeong- Ilgi, written by Cho, Jae-ho, and the Miam-Ilgicho, wtitten by Yoo Hee-chun. Those who had been appointed as a Gamsa by the Sammang System went through the Saeun and Sajo procedures to thank and say goodbye to the king before leaving for his assignment. The Gyoseo and Yuseo were usually received from the king at this time, but in some cases, they were received in the Seungjeongwon, or the Seori of Seungjeongwon brought them directly to the place where the Gamsa works. The Milbu with the Eoab was received along with the Yuseol, and the principle was to return the Milbu later. The procession of Gamsa is divided into the pre-and post-Gyoinsik procession and the Sunryeok procession. It was confirmed that the pre-Gyoinsik procession was made more compact than the post-Gyoinsik procession. In the study, we reviewed Ilsan, which is necessary for the officials' procession, and also examined the Gyoseo, Yuseo, Jeol·Wol, and Milbu received from the king. We also looked at the Gwan-in and Byeongb given by the former Gamsa at the the Gyoinsik. The Jeol, which means the command and the Wol, which means killing power, were given to the Gamsa. And unlike previous studies, it was confirmed that the Jeol was a perforated hexagon and and the Wol was a trident. Also, it was found that Ilsan is white, and there are two rows of Yuso on each of the six ribs of the umbrella. It is thought that the results of this study, which looked at the Doim process and Uimul by dividing the Gyeongsang-Gamsa Doim procession in the late Joseon Dynasty pre-and post-Gyoinsik, will be helpful in understanding the process of Gasmsa Doim. In addition, it is expected that it can be used as basic data for reproduction event of traditional culture related to Gwana, such as the reproduction of Gyeongsang-Gamsa Doim-Sunlyeok procession and Gyoinsik.

We surveyed the occurrence of Japanese yam mosaic virus (JYMV) on Yam in Gyeongsangbukdo pronvince from 2013 to 2015. The symptoms of JYMV were yellow stripes and chlorosis in yam leaves and the infection rate was ranged from 33.6% to 40.8%. We determined nucleotide sequence encoding the polyprotein of JYMV isolate BRI from yam leaves using next-generation sequencing (NGS) method. The partial nucleotide portion (7,736 nucleotides) of the genomic RNA of the JYMV isolate BRI has been sequenced (accession No. KU309315). The region sequenced includes a single open reading frame (ORF) encoding a polyprotein composed of 2,497 amino acids containing the coat protein (CP) and 3' untranslated region (UTR). The genomic organization of this isolate shows almost the same to that of other members of JYMV. The JYMV isolate BRI showed 77% to 79% nucleotide identity with the Japanese and Chinese strains and isolates. This is the first report of the genome nucleotide sequence of JYMV from Dioscorea opposita in Korea.

A random study of 574 dairy farms in Gyeongnam area was designed to determine 1) management factors that may be associated with the occurrence of drug residues; 2) the dairy farmer's attitudes and knowledge about residues; 3) how these variables influence the occurrence of residues in dairy cattle. Management factors perceived as having the greatest influence on drug residues in milk were insufficient knowledge about withdrawal periods, errors due to hired help, insufficient identification and record of animals treated for mastitis, dry cow treatment for mastitis, and metritis treatment. Seventy-one percent of farms with residues problem used mixed own feeds compared with twenty-nine percent of farms with premedicated feeds. Factors significantly associated with the occurrence of residues were herd size, increased number of hired persons, increased frequency of use of mixed-own feeds, category of medicated feed, and producer's attitude toward the public health significance of residues. Our findings suggest that residue occurrence was mainly associated with errors due to hired help, insufficient knowledge about withdrawal periods, poor animal identification and records of treatment animals and use of medicated feeds. Any residue avodiance educational program needs to stress how to deal with these factors. This educational program should be directed to dairy farmers and employees, especially temporary employees. In addition, Dairy farmer's attitudes and knowledge about drug residues need to be improved. More evidence on the public healths significance of residues should be available to them. Because belife in importance of public healths concerns was related to successful residue avidance and because 81.3% of the dairy farmers with residue problem thought public healths concerns were less important than economic ones, it would be helpful to provide educational programs specifically directed to this issue. it may be useful to provide programs not only for the dairy farmers but also change of their concerns about on the public healths.

Two different CAI programs have been developed to study the affect of CAI element for the types of learners'performance; (i) one is the 'CAI program 1' including the open questions for the fourth grade (the fourth period of the 'Time and Angle' in chapter 3 of the first term) of the mathematics class in the elementary school, and (il) the other is 'CAI program 2' for the existing methods. The fourth grade of Andong Songhyun elementary school has been chosen as the study subjects (243 learners), and the t-test and learners'interview have also been used to analysis the results of CAI programs. The CAI programs have only been used as the control variable. The developed CAI programs have been applied two different learners'groups to investigate the degree of performance among the superior, average, and inferior learners. For the superior group (p＜.0023) at the t＜3.2268 level and for the average group (p＜.0706) at the t＜1.8211 level the learner' group using CAI program 1 shows the higher performance compared with the learners' group using the CAI program 2, whereas fur the inferior group (p＜.8073) at the t＜.2458 level two programs did not show any difference. The learners interviews show that the superior and average groups have an interest for the open problems, whereas the inferior group do not shows an interest for the open problems. Thus, the CAI programs including the open questions (open fields, open evaluation) will be helped to the learners' group with the individual differences. Furthermore, it is expected that the CAI programs including the open questions as the mathematics and the program model of CAI can be used to develope the CAI program in future.

The purpose of this study was to undrstand the emotional and behavioral sequela in the abused child caused by phygical abuse. To achieve the purpose. the emotional and behavioral differences between not or less abused children group and severely abused children group were compared in this study. The subjects in this study were 61 male children who were selected among children under custody at 4 child-welfare institutions in Seoul. A violence scale in CTS(Conflict Tactics Scale) developed by Straus(1979) was modified and used as a research tool to measure the children's physical abuse. The Korean text of Child Behavior Checklist(CBCL) was also used to measure the emotional and behavioral problems of abused children. The results of this study were as follows : 1) The total scores of behavioral problems in physically abused children were significantly higher than those in control group. 2) The comparison of behavioral problems has shown significant differences between two groups in social withrawal. somatic symptom, emotional disturbance, obsessive-depressive behavior, hyperactivity and psychotic-sexual factors. However. there were no differences in aggressive and delinquent factors. The above results presents us the profile of children's emotional and behavioral problems caused by physical abuse, and can be used as a framework for the treatment protection and preservation of abused children in the course of social work practice.

In this study, we developed a PC - based motorcycle simulator based on the development technology of a virtual patrol motorcycle training system. This simulator has been developed to be applied to a variety of fields such as driving training for beginners, driver factor research, and system development such as ABS, which can be seen in advanced models. The weight of the motorcycle operated by the patrol guards is more than 400Kg. There is a lot of risk due to the nature of work without prior practice. Therefore, we implemented a study on the untilization of physical stress and temporal pressure in emergency situations. In order to get a feeling that the motorcycle simulator is operating in real-life, it is important that the mutual reliable signal transmission and operation feel between the driver and the simulator. In order to achieve this, we developed a system that can apply the sub-systems of the actual vehicle to the motorcycle simulator in order to generate the same operation feeling as the actual vehicle. Based on these results, we have developed a method of generating a feedback queue.
