In this study, current status of domestic deer farms and its feeding were surveyed. The information of supply and demand of feed f3r deers including its industry were also examined and then analyzed to make fundamental data for deer farms and government policy. The results are as follows. 1. Over 40 years old farmers were about 63％ of total deer farms while 20­30 years olds were less than 1％ indicating that young people still evade agriculture. Moreover, considering education, over 52％ of the farmers have bachelor degree showing much higher rates compared to the other agricultural fields. The reason can be assumed that the labor burden is not serious in deer farming while it is not dirty job compared to the other livestock management. Those high­educated people can be easily trained as experts of deer farming to improve its international competition. 2. Most of investigated farms raise Korean spotted deers and Elk showing that the percentage of Elk has greatly increased(However, many farmers have complained about purchasing methods and they insisted that the sales organization should be controlled by government). 3. 57％ of total cost of production is for feed while most of feeds are imported from abroad. It indicated that it is urgent to make counterplan for saving feed cost. 4. It is necessary to develop feeds for deers in the near future while most of the examined farmers currently use normal assorted feed. Typical roughage sources feeds are rice straw, alfalfa hay, browses feed, and so on. Most of them are currently imported except the rice straw indicating urgently needed to develop domestic bulky feed. 5. The present questions are development of processed goods of velvet antler, establishment of reasonable management system, difficulty of velvet antler selling, feed supply, and so on. It is necessary for government and academic world to develop reasonable policy and scientific research program.

There are differences of Cadmium (Cd) urinary concentration which is considered as indicator of renal tubular dysfunction in other countries, so we have reviewed domestic epidemiological data and suggested Korean health based guidance value (HBGV) for Cd to improve an efficiency of risk management. We decided to apply the WHO calculation model which considered the relationship between dietary intake and Cd concentration in urine sample. It is determined that Cd concentration 2.5 ug/g creatinine in urine as the prevalence of renal tubular dysfunction based on epidemiological data, because there is no renal tubular dysfunction and injury/lesion such as proteinuria at the concentration of 11.63 ug/g creatinine which is the highest Cd concentration in urine from the domestic epidemiological data. It is identified that the ratio between the Cd dietary consumption (8.3~10.4 ug/day) and Cd urinary concentration (0.38 ug/g creatinine) in Korean adult who predicting never been exposed to Cd are 21.8~27.3 and then it is applied to the corresponding model suggested by WHO. Also it is applied that 10% of bioavailability and 50% of excretion rate of absorbed to body (the ratio is 24) were assumed. The estimate of daily Cd consumption level which begins tubular dysfunction is 1 ug/kg bw/day, so we suggest the Korean provisional tolerable weekly intake (PTWI) as 7 ug/kg bw/week.

Based on the results that the extract of Korean mistletoe (KM-110) has immunological and anti-tumor activities and its main component is lectin called KML-U, this study was carried out to investigate the immunostimulatory and anti-tumor activities of FKM-110, fermented KM-110 with lactobacillus, as a basic study for the development of functional food with anti-tumor activity. The amount of lectin after fermentation determined by ELISA was varied with the fermentation time and kinds of lactobacillus. Cytotoxic effects of FKM-110 on the various tumor cells was significant and dependent on the concentration of KML-U and the kinds of lactobacillus. FKM-110 stimulated macrophage and resulted in the secretion of some cytokines such as IL-1 and $IFN-{\gamma}$, but this effect was not correlated with the concentration of lectin. FKM-110 fermented with Marshall Lactobacillus casei showed the most potent antitumor activity in experimental and spontaneous metastasis models. When yoghurt produced with KM-110, Marshall Lactobacillus casei and skim milk was administered orally to mouse, the metastasis of tumor cells was significantly inhibited.

The results of analyzing the outfits of male and female characters depicted in the "Hoehonryedocheop" (回婚禮圖帖, Deoksu 6375) held by the National Museum of Korea and estimating its production date of the "Hoehonryedocheop"are as follows. Firstly, an elderly groom is depicted wearing a patterned heukdanryeong (黑團領) with rank badges, a garment commonly donned by government officials in works such as "Jeonanryedo (奠鴈禮圖)" and "Gyobaeryedo (交拜禮圖)". And the old groom in "Heonsuryedo (獻壽禮圖)" "Jeobbindo (接賓圖)" and "Jungroeyeondo (重牢宴圖)" is shown wearing a jarip (purple hat) without a paeyoung (ornamental jewelry strap), accompanied by jade colored robe with a red strap belt. Gireokabeom (雁夫) is observed wearing a jarip (紫笠) adorned with a paeyoung (貝纓) and a patternless heukdanryeong with rank badges. Adult male descendants are depicted wearing dopo (道袍), while guests wear dopo, cheolrik (帖裏), and jikryeong (直領), accompanied by red and blue straps denoting their social status. Jingssi (徵氏), sidong (侍童), and young grandchildren are observed wearing jungchimak(中赤莫). The young servants are wearing jungchimak, and the boys carrying the food have braided their hair and worn sochangu (小氅衣), while adults servants wore jeonrip (氈笠) and sochangui. Performers are seen clad in a sochangui, jeonbok, and a blue sash around their waists. Secondly, the elderly bride is portrayed wearing a keunmeori (ceremonial headdress) and a green wonsam (圓衫) in "Gyobaeryedo," while in "Heonsuyeondo," she is depicted in a blue skirt and a jade colored jeogori (赤古里). Women descendants are shown adorning headdress decorations, such as binyeo(簪), banja(斑子) and pearl daenggi (眞珠唐紒) on their eoyeomeori (於于味, ceremonial headdress). They are further dressed in skirts of navy, red, and jade hues, paired with various-colored jeogori. Additionally, a woman wearing a navy skirt and a green jangot (長衣) is also depicted. The dongnyeo (童女, unmarried women) wear beolsaengmeri (娘子雙髻), headdress) with long binyeo and long dodaik-daenggi (都多益唐只). They wear chilbo-jokduri (七寶簇頭里) and a red skirt with a green hoejang-jeogori (回裝赤古里). Bija (婢子) wears garima (加里亇) on her eoyeomeori and is seen dressed in skirts and jeogori resembling those worn by noble women, albeit with lighter colors, shorter skirt length, and a subdued volume. Ginyeo's attire bears similarities to that of noble women, although with a dress with less vibrant tones and devoid of decorations on the eoyeomeori. Thirdly, based on the main character's jarip, along with the cheolrik and jikryeong worn by the guests, as well as the performances by musicians of the military camp, it is suggested that the main character of the 60th wedding anniversary is connected to the Ministry of Military Affairs or the military camp. Judging by the military band's short-sleeved vest, the silhouettes of the women dress, and the headdresses, it is likely that the "Hoehonryedocheop" was produced between the 1760s and 1780s.

As implant treatment has become popular, lots of different shapes and materials of the implant upper component have been supplied. And there are also diverse reports about failures including loosening of the abutment screw which is one of the most common reason. Purpose : The purpose of this study is to find out how different screw tightening orders and methods influence on screw loosening according to the different connection systems. The upper component was fabricated by casting method. After fabricating master models that are precisely attached to the upper component, 5 experimental models each for the external connection system and internal connection system were fabricated using splinting impression technique. First, to find out the influence of the screw tightening order, screws were tightened in 3 orders; 1-2-3-4, 2-3-1-4, 2-4-3-1. After tightening, removal torque values (RTV) of each group was measured. And also to find out the influence of screw tightening method, a model with 2-3-1-4 screw tightening order was tightened with 30 Ncm at one time(1-step method) and the RTV was compared with the same order group (2-3-1-4) in the 2 step method. In the external connection system, RTV appeared significantly lower in group 2-3-1-4 than group 2-4-3-1 (p<0.05). And also in the internal connection system, the RTV of group 2-3-1-4 appeared significantly lower than that of group 2-4-3-1 and 1-2-3-4 (p<0.05). When comparing the tightening number of the screw without considering the screw tightening order, the first tightened screw appeared significantly higher RTV than the second one in the external connection system (p<0.05), however there was no significant difference from the first tightened screw to the last tightened screw in the internal connection system. And there was no statistically significant difference between the two screw tightening methods in both internal and external connection system. In the comparison of external and internal connection system, each RTV appeared 16.27 Ncm and 14.25 Ncm and appeared as a statistically significant difference (p<0.05). There was a significant difference in RTV measured according to the screw tightening order. The lowest RTV appeared in the groups started tightening from the middle. There was also a significant difference in RTV between the two connection system groups. A further study is needed to find out the influence factors in RTV and also a study is required related to the load condition.
