  • 저급의 고지 원료를 두께 방향으로 고온 압착을 가하여 건조함으로써 전반적인 종이 물성 을 향상시키는 콘디벨트 건조 방식은 70년대 중반부터 80년대에 이르는 10여년에 걸친 개발 과정을 거쳤으며 90년대에 들어서 핀랜드의 Inkeroinen에 위치한 V alemt- Tarnpella의 연구 소에 최초의 파일로트 설비가 설치되었으며 그 후 1996년에는 핀랜드 ENSO사의 P Pank밟oski 판지공장에 설치됨으로써 세계 최초의 상업생산설비를 이루게 되었다. 기존의 실린더 건조 기술과 비교할 때 콘디벨트 건조방식은 건조속도를 약 5-15배 향상시킬 수 있 으며, 건조 에너지 절감에 큰 효과가 있을 뿐만 아니라 기존의 실린더 건조시 종이가 폭방 향으로 수축되 어 인장 stiffness와 압축 강도 동의 종이 물성 이 저 하되 는 반면 습윤상태 의 섬유를 120도씨이상에서 가열에 의해 리그닌을 연화시킴과 동시에 섬유의 유연성을 증가시켜 준다. 그리고 높은 압력을 가해줌으로써 섬유간의 결합 면적을 증가시키고 건조시 종이의 폭방향의 수축을 감소시켜 인장강도, 내부결합강도, 밀도, 표면평활성, 투기저항성 등 종이의 물성을 대폭 향상시켜주는 혁신적인 제지기술로 인정받고 있으며 국내의 경우 현재 1998년 부터 상업생산을 이루어짐으로써 그 공헌도는 매우 크다고 할 수 있다. 골판지의 주원료가 되는 국산 골판지 고지 (Korean old corrugated container, K KOCC)의 거듭된 재생처리로 인하여 미세분의 함량이 전체 지료의 절반 이상에 달할 뿐만 아니라, 섬유가 각질화와 단섬유화로 인하여 고온압착 건조처리 만으로는 골판지 고지로 생 산된 원지의 강도를 버진펄프로 생산된 원지가 가지는 강도에 준하는 강도로 향상시키는데 한계점을 가지게 된다. 유럽의 제지선진국들은 골판지 원지의 강도를 향상시키는 방편으로 표변에 전분 사이즈 프레스 처리를 도입하였으며 본 연구에서는 고온 압착 건조 처리 설비를 활용한 전분 표면처리의 가능성을 검토하고 골판지 원지의 강도를 향상시키기 위한 표면처리조건을 탐색하였다.

  • Rats were adapted to diets containing 10% cellulose,10% sodium alginate and fiber-free diet for 5 weeks. Following a 14 hour fasting, rats were fed 5g of a test meal that provided 50% energy from fat, then killed at 4 hour postprandially. Plasma and lipoprotein fraction-cholesterol levels were lower in sodium alginate-fed animals than in rats fed other diets. Plasma TG did not differ among diet treatments. Increase in TG content of HDL fraction occurred in dietary fiber groups. Intestinal apolipoprotein B level and lipase activity were lower in sodium alginate-fed group than in other dietary groups. These results suggest that chronic consumption of sodium alginate affects plasma cholesterol level as in the case of fiber supplemetation, but is less likely to modify the acute Plasma TG response to high fat meal than if a fiber supplement is incorporated into the meal.

  • Among the oriental medicine compounds, sulfur is known as a heat-generation material in a human body. Heat-generation reaction results in the consumption of energy source. Some oriental herbs are used to treat obesity and blood lipid composition. Therefore, we hypothesized that a sulfur containing oriental medicine compound, called as Hangbisan, could help weight loss of experimental rats. This study was designed to observe the change of weight of Sprague-Dawley (SD) rats that had been fed with high-fat diet containing 10% cellulose or Hangbisan for 9 weeks. Hangbisan affected the weight loss of rats as reducing the level of plasma cholesterol and triglyceride and increasing the level of HDL-cholesterol. Thus, this study revealed Hangbisan have an anti-obesity effect and a potential role for anti-obesity agent in the application of oriental medicine compounds.

  • 본 연구는 항비만 기능성을 가지면서 맛과 향이 증진된 분말형 다진양념(다데기)을 개발하기 위해 첨가할 수 있는 약용작물들의 선정 및 그 기능성을 평가하기 위해 실시되었다. 오미자, 진피, 감초, 녹차엽 등을 첨가군으로 선정하여 각각의 시료들을 8시간, $80^{\circ}C$ 증류수에서 추출 후 감압농축하여 추출물을 제조한 뒤 마우스 유래 adipocyte (3T3-L1)에 처리하여 세포내 지방 축적 억제 정도를 실험하였다. 시료 처리 배양 5일 후 오미자, 진피, 감초, 녹차엽 추출물을 처리한 모든 군에서 대조군과 비교시 20% 이상 세포내 중성지방 농도가 감소하였으며 특히 오미자 군에서는 30% 이상 감소를 보였다. C57BL/6 생쥐를 이용하여 고지방식이로 비만을 유도하면서 분말형 다진양념, 오미자, 진피, 감초, 녹차엽 추출물을 경구투여한 뒤 체중증가를 조사한 결과 8주 후 고지방식이와 다데기만을 경구투여한 군은 고지방식이군과 비교하여 체중감소경향만을 보였으나 분말형 다진양념과 추출물을 함께 경구투여한군에서는 유의적으로 체중이 감소하는 결과를 보였다. 이들 추출물을 혼합하여 제조한 분말형 다진양념은 관능검사에서도 고춧가루 특유의 풋내를 감소시켜 향미가 증진되는 것으로 평가되어 오미자, 진피, 감초, 녹차엽을 첨가한 다양한 항비만 기능성 양념 개발이 기대된다.

  • This study was carried out to investigate the effect of body weight reduction of noddle contained glucomannan in high fat diets-induced obese rats. Male Spraque-Dawley rats were randomly assigned to control and high fat diets groups for 4 weeks. Four weeks later, the control and high fat diet grpups were rearranged into 4 groups by different levels of nuddle containing glucomannan. After 5 weeks of feeding, serum and whole blood was analyzed. Obesity index was significantly lower in the group fed nuddle contained glucomannan than that of high fat diet groups. The status of white blood cells in hematological examination was significantly higher in rats fed high fat diet and was not significantly different by fed nuddle. Serum albumin levels were not significantly different although glucose levels in serum was significantly different among groups. Serum triglyceride and Total cholesterol levels were the highest levels in rats fed high fat diets and showed the lowest levels in rats fed nuddle.

  • This study investigated the effects of exercise on genistein-induced adipose tissue reduction and anti-inflammation of adipose tissue in ovariectomized mice fed a high-fat diet. Compared to mice fed a high-fat diet (C), both genistein (G) or exercise only (Ex) not only decreased adipose tissue weight and adipocyte size, but also glucose and free fatty acid levels in serum, which were more effectively reduced when genistein and exercise were treated simultaneously (G/Ex). The expression of lipogenesis and inflammatory cytokine genes of both G and Ex in adipose tissue was decreased compared to C. In particular, the decrease of these genes expression in G/Ex was more effective than each treatment alone. Thus, this study revealed that simultaneous treatment of genistein and exercise resulted in more effective improvement of obesity and adipose tissue inflammation than genistein single treatment in ovariectomized mice fed a high-fat diet, and it is a result of positive regulation of lipogenesis genes. This study suggests that the exercise has a beneficial effect on anti-obesity and adipose tissue anti-inflammation of genistein.

  • The purpose this study was to investigate the influences of 5% mung bean (Phaseolus aureus L.) on BUN and enzyme activities in serum of hyperlipidemic rats. Sprague-Dawley(SD) rats (24 male) were divided into four groups, namely the BD group(normal-nonhyperlipidemic diet), BM group(normal-nonhyperlipidemic diet+5% mung bean), BH group(control-hyperlipidemic diet), and BHM group(hyperlipidemic diet+5% mung bean). Serum concentrations of blood urea nitrogen (BUN) and uric acid were significantly decreased (p<0.05) by mung bean supplementation diet. The activities of AST, ALT, ALP, LDH, amylase and lipase in sera of mung bean diet group were significantly decreased (p<0.05). The catalase activity in serum of mung bean supplementation group was significantly increased than hyperlipidemic diet (p<0.05). In vivo experiment with hyperlipidemic rats showed that ingestion of mung bean were effective in kidney and hepatic functional enzyme activities. Which suggests that mung bean material could be used for further studies as a potential source for nutraceutical foods.

  • The object of the present study was to examine the effect of selenium-treated Spinacia oleracea L. on antioxidative defense system and oxidative damage in rats fed high-fat and high-cholesterol diets. Experimental rats were divided into six groups which were composed of normal diet group (N), high-fat and high-cholesterol diet group (HF), high-fat and high-cholesterol diet with 5% or 10% non-treated spinach supplemented group (SPA or SPB) and high-fat and high-cholesterol diet with 5% or 10% selenium-treated spinach-supplemented group (SSA or SSB). In the antioxidant enzyme activities of hepatic glutathione peroxidase and superoxide dismutase, activities increased in supplementation of non-treated or selenium-treated spinach groups compared to HF group. However, there was no significant difference in the activity of hepatic catalase among all experimental groups. The microsomal superoxide radical content of the SSB group was significantly reduced compared to the HF group. The mitochondrial carbonyl values of the SSB group were significantly reduced compared to the HF group. Thiobarbituric acid reaction substance (TBARS) values in RBC and liver were also reduced in non-treated or selenium-treated spinach-supplemented groups compared to the HF group. The hepatic TBARS values of the supplementation of selenium-treated spinach groups significantly decreased compared to the supplementation of non-treated spinach groups. These results suggest that selenium-treated spinach may reduce oxidative damage by the activation of antioxidative defense system in rats fed high-fat and high-cholesterol diets.

  • The Nam-Hae Sin-sa, the South Sea shrine in Yeong-Am, Korea was a national institution for public peace and bliss, was excavated in 2000, and the shrine and the 3-way-gate were reconstructed in 2001. Hae Sin-sa, the Sea shrine is a place for religious service separated into the Nam-Hae Sin-sa, the Dong-Hae Myo, and the Seo-Hae Dan. The Dong-Hae Myo was reconstructed, but restored shrine and 3-way-gate of the Nam-Hae Sin-sa is not perfect in comparison with excavation plan in 2000, therefore new reconstruction was researched through the related literature, the analysis of historical maps and excavation results, the interview with the concerned people and the case study. This research defines the analysis of the Plan of the Nam-Hae Sin-sa Reconstruction as follows. 1. The Nam-Hae Sin-sa was the institution for religious service operated by national direct management, represents the shrine for public peace and bliss on the Mountain, the Sea, and the River. Especially the Nam-Hae Sin-sa had an important position on the pivot of international trade with China and Japan, and had a role of main shrine with another one in the Mt. Ji-ri San. 2. The name of the Sea shrine was called as Nam-Hae Sin-sa(the South Sea shrine), Dong-Hae Myo(the East Sea shrine), Seo-Hae Dan(the West Sea shrine). But the name of the South Sea shrine had changed in the early period of Chosun as Nam-Hae Sin-sa to the later Chosun as Nam-Hae Dang through the research of related literature and historical map. Such as the Seo-Hae Dan, it was constructed for the Dan, the flat raised-floor without buildings, and changed to the type of Sa-Dang with addition of buildings. 3. The historical map of Hae Sin-sa informs the types of the roof, the Mat-bae roof was used in the Dong-Hae Myo, but the Pal-jak roof was showed in the Seo-Hae Dan and the Nam-Hae Sin-sa. 4. According to the analysis of Yong-Ch'uck the unit length, Nam-Hae Sin-sa was reconstructed in the period of Koryo on large scale, but it was restored in the Chosun on middle scale. And the Unit of Yong Ch'uck was changed into Yeong-jo Ch'uck in the period of Chosun. 5. As the results, The Plan of the Nam-Hae Sin-sa Reconstruction designed the new shrine into the 3 Kan front and the 2 Kan side with 3:2 scale. An-ch'o-gong with Yong-du and Yong Mi the ornaments represents head and tail of dragon, the Un-gong and the ornament of Pa-ryun-dae-gong in the building, and the Ch'ung-ryang of the Yong-du show the image of the institution for religious service for the god of the sea who look like dragon. The inner gate building and the main entrance were designed as same plan and scale as Hyang-gyo, the Korean Traditional School and Shrine of Confucianism, on the basis of results of excavation. Raise the 3-tall gate of the main entrance with harmony of the scale and the shape, because the side of gate building has the Mat-bae roof. 6. This research shows that Plan of the Nam-Hae Sin-sa Reconstruction is composed into shrine space and reservation space from the main entrance to inner gate and shrine like Jung-ak Dan in the Mt. Gye-ryong San, and it also informs the well in the west side of Sin-sa is an important factor of the plan of shrine architecture.
