This study was conducted to investigate the effect of a forest healing program from a psychomotor perspective on the forest experience level of middle-aged adults. The program was constructed by applying forest healing elements in the forest from a psychological exercise perspective, and the effect of a forest healing program from a psychological exercise perspective on the forest experience level of middle-aged adults was studied. This study used the Forest Experience Scale with a total of 9 items consisting of three elements of experience - cognitive freedom, intrinsic motivation, and cognitive competence. It was developed by Kim youn-soo in 2017 and based on Deci and Ryan’s theory of self-determination. From September 2 to September 24 in 2019, the forest healing program from the perspective was conducted for middle-aged adults living in the C city in their 40s and 60s. A total of 12 sessions were carried out, each session lasted for about 40 minutes and two sessions were conducted a day. This study attempted to present a broad understanding of the body s ability to understand humans and adapt to the environment through the forest healing program from a psychomotor perspective.

A variety of digestive Enzymes of pancreatic and intestinal origin participate in the breakdown of protein, carbohydrate and lipids. It has been known that some of enzyme output of the intestinal glands can be manipulated by altering components of the diet. The incidence of patients who are suffering from gastrointestinal trouble in Korea is much higher than that of the United States. This fact might correlate with diet composition of Korean and American dishes. These facts are attractive for us to study the effect of diet composition on the digestive enzymes such as amylase, lipase, trypsin and chymotrypsin, and to decide whether the difference of diet composition affects these enzymes and whether such high incidence of gastroin testinal patients in Korea could be adequately explained by change in digestive enzyme activities of the animals fed with different diet. Our previous experiments have shown that pancreatic enzyme activites of rats fed with 5% casein diet which was prepared similarly to Korean diet in terms of protein content only were depressed as much as one fifth of that of control during two weeks feeding period. but it is true that protein is not only depleted but fat is also depleted in Korean dishes. The primary objective of the experiments described herein was to study the effect on the pancreatic enzyme activities of diet which was similarly prepared to Korean dishes and also to study the effect on the pancreatic enzyme activities of varying the proportion of fat to carbohydrate in the diet which is keeping the diet isonitrogenous and isocaloric. Data from this experiment will be discussed ire conjunction with previously published results conducted in our laboratory in order to illustrate how the high incidence of gastrointestinal patients in Korea could be adequately explained by diet prepared in similar composition to the Korean dishes. In a random distribution, male albino rats, weighing the average of 80 gm each were divided into five groups. Group I ; 5% casein : no fat : carbohydrate Group II ; 5% casein : 12% fat : carbohydrate Group III ; 18% casein : no fat : carbohydrate Group IV ; 18% casein : 12% fat : carbohydrate Group V ; 18% casein : high fat : carbohydrate (ratio of fat to carbohydrate 94 : 6) Calorie difference from protein or fat depletion was substitiuted by carbohydrate. At the end of designated time interval, the rats were sacrificed 14-15 hours after the last meal by decapitation. The pancreas was carefully romoved and placed in a cold 0. 25M sucrose solution (4℃). A 5% homogenate in 0.25M sucrose was prepared from the glandular {free of obvious lymph nodes and adipose tissue) portion of the pancreas. 5:% Homogenates were centrifuged (14,000 x g) for 15 minutes to remove cellular debris and whole cells. Enzyme analysis and protein determination were subsequently performed on the supernatant. Protein was determined by Lawry method (1951). Enzyme activity assays were performed using modification of Hepler method (1962) for amylase and the method developed by Cherry and Crandall (1932) for lipase. Chymotryptic assays were performed using a modification of method developed by Rhodes et al. (1957), as a substrate for chymotrypsinogen N-acetyl-L-tyrosine ethyl ester was used. Trypsinogen assay was similarly performed using p-toluene-sulfonyl-L-arginine methyl ester as a substrate. The assays were linear with respect to enzyme concentration over the range used under specified conditions such as temperature (37℃) and incubation period, 30 minutes for amylase, 1 hour for lipase, and for the trypsinogen and chymotrypsinogen the recording of dye disappearing of optical density was recorded 2 to 3 seconds after adding substrate-buffer-indicator The results of the experiments in which the effect of different composition of nutrient which was prepared in similar composition to Korean dishes on pancreatic enzyme acitivities are summarized as the following. When the enzyme activity

Micoromorphological alterations of sea-waterlogged woods by marinemicro-oragnisms were investigated by the light and scanning electron microscopy as a part of serial investigations on the shipwrecked materials which were excavated at the sea shore of Wando-Kun, southern coast of Korea in 1984.Deterioration of sea-waterlogged wood by marine microorganisms were varied with the wood species. The degree of deterioration even in the same wood specieswas different according to the part where it was in mud of sea-water. However, the resistance of Torreya nucifera over the marine organisms was marked. Deterioration in cell wall may be classified into three types; thinning of cell wall, separation of secondary wall from compound middle lamella and tunneling of cell wall. Thinning and separation were frequently observed, while the tunneling was rare. Among the wood cell elements of hardwoods, vessel wall was the least deteriorated. The difference degree of degradation of cell wall constituents and the accumulation of inorganic substances in cell lumen indicate that some factors to be considered for the conservation treatment were discussed. The kinds of marine microorganisms invading and/or inhabiting in wrecked wooden ship were also discussed.

After a partial mastectomy, large or ptotic breasts can be reconstructed using breast reduction techniques. Wise-pattern reduction is typically used to remove masses in any quadrant of the breast, but this technique leaves a large inverted T-shaped scar. Instead, the short scar periareolar inferior pedicle reduction (SPAIR) technique involves a periareolar line and does not result in a scar along the inframammary fold (IMF). A 49-year-old patient with macromastia and severely ptotic breasts was diagnosed with invasive cancer of the left breast. Her large breasts caused pain in her back, shoulders, and neck. She also expressed concern about postsurgical scarring along the IMF. In light of this concern, we chose the SPAIR technique, and we designed and performed the procedure as described by Hammond. During surgery, we removed 36 g of breast tumor and 380 g of breast parenchyma from the left breast. To establish symmetry, we also removed 410 g of tissue from the right breast. Postoperatively, the patient reported satisfaction regarding the reduction mammaplasty and, in particular, noted decreased back, shoulder, and neck pain. In summary, we used the SPAIR technique to achieve oncologic and aesthetic success in a patient with macromastia and a tumor located lateral to the nipple-areolar complex.

In this study, land farming and chemical oxidation of a diesel-contaminated site is compared to evaluate the environmental impact during soil remediation using the Spreadsheet for Environmental Footprint Analysis by U.S. EPA. Each remediation process is divided into four phases, consisting of soil excavation, backfill and transportation (Phase 0), construction of remediation facility (Phase 1), remediation operation (Phase 2), and restoration of site and waste disposal (Phase 3). Environmental footprints, such as material use, energy consumption, air emission, water use and waste generation, are analyzed to find the way to minimize the environmental impact. In material use and waste generation, land farming has more environmental effect than chemical oxidation due to the concrete and backfill material used to construct land farming facility in Phase 1. Also, in energy use, land farming use about six times more energy than chemical oxidation because of cement production and fuel use of heavy machinery, such as backhoe and truck. However, carbon dioxide, commonly considered as important factor of environmental impact due to global warming effect, is emitted more in chemical oxidation because of hydrogen peroxide production. Water use of chemical oxidation is also 2.1 times higher than land farming.

IBA와 NAA 처리에 의해 생성된 Ethylene이 인삼(Panax ginseng C.A. Meyer) 부정근의 생장과 발달에 미치는 영향

김윤수,한은주,백기엽,Kim, Yun-Soo,Hahn, Eun-Joo,Paek, Kee-Yoeup 한국식물생명공학회 2003 식물생명공학회지 Vol.30 No.2

The effect of IBA and NAA on adventitious root cultures of Panax ginseng C.A. Mater were investigated. Results indicated differences in growth and development of the roots according to 5mg/L IBA and 2mg/L NAA. IBA resulted in a normal root development and a higher growth compared to NAA. The roots formed on NAA-containing media were shorter and thicker than those in IBA, showing a hypertrophy of the root tip. NAA induced more than 1.6 times higher ethylene production compared to IBA, which caused inhibition of the root growth. Under the ventilation, in the other hand, on difference was observed in ethylene concentration and the root growth between IBA and NAA treatments. Under ventilation ethylene production was not detected until 10 days of culture, while detected from the initial stage under on ventilation. The results suggested the importance of ventilation during the culture for the growth and development of ginseng adventitious roots.

생물반응기의 형태에 따른 인삼부정근의 생장과 ginsen-side의 생산능력에 대하여 조사한 결과, 원형의 상부와 하부에 5 cm의 bubble column을 가진 bulb type bubble bioreactor (BU)에서 건물중은 41.92 g으로 가장 많이 증가하였으며, cylindric tube bioreactor (CT)에서 건물중이 38.55g으로 가장 낮게 나타났다. 이들 두 생물반응기의 초기 kLa 값은 BU 생물반응기에서 6.98 h$^{-1}$로 가장 높게 측정되었고, 반대로 bubble column이 없는 CT 생물반응기에서 5.25 h$^{-1}$으로 가장 낮게 측정되었다. 그러나 이와 같은 초기 kLa값의 차이는 부정근내의 이차대사산물인 ginsenoside의 함량에는 영향을 주지 않는 것으로 나타났다. 또한 BU 생물반응기에서 bubble column의 길이를 기존의 5 cm에서 10 cm로 연장시켰을 때, 초기 kLa값이 6.52 h$^{-1}$에서 7.80 h$^{-1}$로 증가하면서 인삼부정근의 생장을 42.13 g에서 50.30 g으로 약 16% 증가시킨 것으로 나타났다. The type of air lift bioreactor affected the root growth in ginseng adventitious root cultures. Among bioreactors used in this experiment, bulb type bubble bioreactor (BU) was the best to increase root growth (41.92 g dry weight). The kLa value representing the oxygen transfer capacity from medium to explants (6.98 h$^{-1}$ ) in BU with 5 cm bubble column was higher than other bioreactors. On the other hand, cylindric tube bioreactor (CT) without bubble column resulted in minimum root growth (38.55 g dry weight) and kLa value (5.25 h$^{-1}$ ). Furthermore, the root growth (50.30 g dry weight) in BU with 10 cm bubble column more increased than 5 cm bubble column. However, the kLa value do not affected the secondary metabolite such as ginsenosides. These results show that the bubble column in air lift bioreactor increase kLa value and increased kLa value stimulate the growth of ginseng adventitious roots.

In manufacturing sites, bearing fault in eletrically driven motors cause the entire system to shut down. Stopping the operation of this environment causes huge losses in time and money. The reason of this bearing defects can be various factors such as wear due to continuous contact of rotating elements, excessive load addition, and operating environment. In this paper, a motor driving environment is created which is similar to the domestic manufacturing sites. In addition, based on the established environment, we propose a dataset for bearing fault detection by collecting changes in vibration characteristics that vary depending on normal and defective conditions. The sensor used to collect the vibration characteristics is Microphone G.R.A.S. 40PH-10. We used various machine learning models to build a prototype bearing fault detection system trained on the proposed dataset. As the result, based on the deep neural network model, it shows high accuracy performance of 92.3% in the time domain and 98.3% in the frequency domain.

기질이 이당류 분해효소 적응성에 미치는 실험적 연구

In most mammals, levels of lactase are high during infancy but by the time adulthood is reached these levels of lactase are deficient. So far, the exact mechanism involved in the appearance and disappearance of lactase is not known. The present experimental study describes the digestive enzymatic adaptation of disaccharidase to the substrate in diet composition in order to investigate whether the mere presence of corresponding substrate in the diet suffices to stimulate disaccharidase or not, probably by $quot;turning on$quot; which encodes for the synthesis of these enzymes. Our experimental studies suggest that lactase activity in the newborn of the rat immediately after normal birth is at a peak and remains there through the lactating period; however, disappearance of lactase was observed four days after weaning. It reappeared in seven days after the rat, which had been fed for 150 days on a sucrose diet, was shifted to a lactose diet, However, the activity was weaker than that of the lactating period, indicating that enzymatic adaptation of latose to the substrate in diet may be related. On the other hand no surcease levels were found throughout the lactating period, but the levlel of surcease rose independently of the sucrose diet intake after weaning, indicating that the sucrose in the diet did not seem to influence the surcease activity at all.
