Purpose: Negative pressure therapy has been used in various conditions to promote wound healing. It has also been used to secure a skin graft by improving microcirculation and improving tight adhesion between the graft and the recipient bed. To reduce post burn scar contracture and improve aesthetical result, many types of dermal substitutes have been invented and used widely. The goal of this study was evaluate usefulness of the VAC (Kinetic concepts Inc., San Antonio, TX) in improving the take rate and time to incorporation of Integra$^{(R)}$ in reconstruction of burn scar contracture. Methods: A retrospective study was performed from October, 2006 to December, 2008. The VAC was utilized for 11 patients. The average patient's age was 19.7 years (range 5 - 27) and average surface area was $785cm^2$ (range 24 - 1600). The burn scars were excised deep into normal subcutaneous tissue to achieve complete release of the scar, Integra$^{(R)}$ was sutured in place with skin staple와 Steri - strip$^{(R)}$. Then slit incisions were made on silicone sheet only with No.11 blade for effective drainage. The VAC was used as a bolster dressing over Integra$^{(R)}$. Negative - Pressure ranging from 100 to 125 mm Hg was applied to black polyurethane foam sponge trimmed to the appropriate wound size. An occlusive seal over the black polyurethane foam sponge was maintained by a combination of the occlusive dressing, OP - site$^{(R)}$. The VAC dressing changes were performed every 3 or 4 days until adequate incorporation was obtained. The neodermis appeared slightly yellow to orange color. When the Integra$^{(R)}$ deemed clinically incorporated, The VAC was removed and take was estimated with visual inspection. Very thin STSG(0.006 ~ 0.008 inches) was performed after silicone sheet removal. Result: The mean time for clinically assessed incorporation of Integra$^{(R)}$ was 10.00 days (range 9 - 12). The mean dressing change was 3.5 times until take was obtained. In All patients, Integra$^{(R)}$ had successful incorporation in tissue without serious complications. Conclusion: Integra$^{(R)}$ in combination with Vacuum - Assisted Closure(VAC) may be incorporated earlier than conventional dressing method.

This study was conducted to investigate dietary patterns and assimilation of dietary culture of Korean descendants in Yanbian, China compared to Korean. A dietary survey was conducted using one 24-hour recall method from 730 adults over 30 years of age in Yanbian, China and 695 adults over 25 years of age in Kuri, Korea. The average number of food items consumed per day was 14 in Yanbian and 20 in Kuri and there was a significant difference between the two regions(p<0.001). The foods consumed most frequently were rice, salt, the M.S.G. in Yanbian and rice, green onion and garlic in Kuri. The foods consumed most by amount were rice, cucumber, Soju in Yanbian and rice, Kimchi and grape in Kuri. The average number of dishes consumed per day was 6.4 in Yanbian, 9.4 in Kuri and the difference between the two regions was significant(p<0.001). Total number of dishes appeared in the survey was 253 in Yanbian and 494 in Kuri. The dishes consumed most frequently were cooked-rice, beverages, Kimchi, stir-fried eggplant in Yanbian and cooked-rice, Kimchi, coffee, soybean paste stew, in Kuri. The dish groups appeared most frequently were rice, stir-fried foods, vegetables and Kimchi in Yanbian and rice, Kimchi, beverages and fruits in Kuri. Male subjects in Yanbian Consumed alcohol frequently while adults in Kuri consumed coffee more frequently than Yanbian. The major meal patterns were rice+side dish, rice+soup, rice+side dish+Kimchi in Yanbian and rice+soup+side dish+Kimchi, rice+side dish+Kimchi, rice+soup+Kimchi in Kuri. Stir-fried foods, which were consumed 46.6% of all the meals, were dominant side dish in Yanbian, but stir-fried food, seasoned vegetables and grilled food appeared aver 10% in Kuri. There results show that variety of diet of Korean-Chinese in Yanbian was lower than Kuri. Korean-Chinese tend to keep traditional Korean dietary patterns of consuming rice as staple but were adapted to Chinese dietary patterns of consuming stir-fried side dishes. Efforts should be directed toward preserving Korean traditional patterns of dietary culture among Korean-Chinese population.

The major problems of food crop cultivation in Korea are low yield of most crops except rice. inefficient cultivation techniques for aged farmers. and low international competibility. Therefore, development of cultivation techniques of food crops should aim the yield. quality improvement, labor reduction and production cost. The primary issue for increasing the yield of soybean, barely and wheat is to reduce the yield gap between the farmer's yield and recommended ones of experiment station. More advanced cultivation techniques needs to be developed. and/or the conventional breeding methods to be reconsidered. The newly developed labor-saving mechanized technique needs to reduce labor hours , and the cost of agricultural implements and machineries. In other words the labor-saving mechanized technique should be developed based on the improvement of total farming system as well as systemic fundamental innovation of cultural methods. The efficiency of solar energy use in food production of Korea in 1997 is as low as $0.52{\%}$ so there is much room to increase yield. It is recommendable that the concept of food Production should be changed to energy Producing efficiency Per unit area basis from volume and weight of food materials. Moreover, introduction of resonable cropping system is needed to increase yield of main crops, farmer's income, solar energy use efficiency, and decrease of land service expenditure. Current cropping system emphasized on economic crops. especially in vegetables , is not desirable for resonable use of arable land. stability of agricultural management and staple food crop self-sufficiency ratio. It is desirable to increase food crops . that are energy of carbohydrate and protein rich and land dependent crops. in cropping system. And the agronomist should develop the cultural methods to replace food crops for food self-sufficiency and stable farming management instead of economic crops in current cropping system. Low-input and environmentally-sound crop cultivation techniques, especially nitrogen-reducing culture technique which is directly related to food crop quality, also needs to be developed urgently. The extended cultivation of corn in upland and barely and wheat in lowland as a feed stuffs is recommended to prevent further decrease of food self-sufficiency ratio, which is mainly caused by the high reliance on imported feed grain. It is also considered that the calculation and presentation methods of standard agricultural income needs to be improved. The current calculation method uses unit land area of 10a regardless of crop kinds , characteristics of agricultural management and cultivation scale. So, it is apt to lead misunderstanding of farm income value. Therefore. it should show an income of average farmers for certain number of years. Research and developing system for food producing is not desirable because they are conducted currently individual crop and mono-culture basis. But actual agricultural income is usually earned by cropping system including upland and lowland. For example. the barley and wheat is usually cultivated in double cropping system. The cooperation among research institutes such as university agribusiness. government and farmers is indispensible. The public information and education on importance and consumption habit of food crops is necessary in Korean society to increase food self-sufficiency through nationwide cooperation.

Objective: This paper reports the possibility of using of a locking horizontal mattress suture technique in repairing lacerations that are difficult to suture with staples. Methods: Data were collected retrospectively over a 6-month period regarding the routine repair of scalp lacerations: those in areas injured by a high energy blunt mechanism, continued to bleed after pressure, nonlinear or damaged skin repaired with a locking horizontal mattress technique, and simple interrupted technique. The effects of the two techniques used to repair scalp lacerations on wound healing, complication rate, and patient satisfaction were examined. The categorical variables are expressed as the number and percent. A Mann-Whitney-Wilcoxon test was used for statistical analysis. A P-value less than 0.05 was considered significant. Results: Thirty-seven consecutive patients with scalp lacerations presented for care. Wound closure was accomplished with the locking horizontal mattress sutures in 40.5% (n=15) (median length, 5.0 cm; interquartile range [IQR], 4.0-7.0 cm). Simple interrupted sutures (median length, 4 cm; IQR, 3.0-5.0 cm) were used in 59.5% (n=22) (P=0.015). The frequency of additional bandage compression (P=0.008), frequency of exudative hemorrhage (P=0.018), and suture mark frequency at suture removal (P=0.047) were significantly lower in the locking horizontal mattress group. Conclusion: The locking horizontal mattress suture, which has the advantage of a horizontal mattress suture, may be one of the ways that can be used alternatively to treat scalp lacerations that difficult to suture with staples.

This study deals with the relationship among trust, attachment and brand loyalty of agricultural products' rice co-brands, which are the staple food of the people. The research method established the hypothesis of the study under the foundation of prior research and developed the survey. The subjects of the study were distributed, retrieved, and analyzed the survey of 163 rice farmers in Buyeo-gun, Chungcheongnam-do. The empirical analysis results show that: First, hypothesis 1 of the brand awareness and image that "rice brand assets will be a positive relationship to trust" were statistically adopted. In particular, statistical t values showed a difference in consumer confidence over recognition>images. Second, hypothesis 2 of the trust of agricultural rice brands will be a positive influence on attachment and loyalty' statistically supported. In this regard, brand trust was higher in loyalty than attachment. Third, the attachment of agricultural products to rice brands will be a positive influence on loyalty,' was statistically supported. The strategic implications of this study are as follows. First, consumers should be given clues of trust(ex, GAP of Natioanl Approval Licesing, Fam Tour) as they distrust the perceived quality of the rice in the market. Second, the effect of the origin of rice is questionable, so the spread of the production power system should prevent the mixing of rice varieties, that is the spread of the production history systems.

This experiment was conducted to explore the cultural method capable of raising of picked cotton ratio and more high-yielding in the middle part of Korea where growth period of cotton is short. By early vinyl-mulching culture, emergence date was earlier, flowering and boll opening were shorter than non-mulching, especially boll opening date was earlier about 8 to 15 days. Plant height was longer by vinyl-mulching, fruiting branches and number of bolls per plant at vinyl-mulching of the 10th April produced more twice than non-mulching of the 10th May. Picked cotton ratio was 79% at non-mulching of the 10th May, while viny-mulching of the 10th April produced most of picked cotton as picked cotton ratio 99%. At vinyl-mulching of the 10th April, lint yield increased more 76-90% than non-mulching. Staple length was some longer and also content of linolenic acid of cotton seed oil was higher than non-mulching.

Rice in Korea is a highly valuable food resource that serves both as staple food and ingredient in various processed edibles. This study was conducted to explore pre-treatment methods for rice that result in good saccharification upon production of rice beer. When rice was subjected to fine grinding, steeping, roasting, gelatinizing, or puffing prior to saccharification with malt, wort containing puffed rice had the highest soluble solid content (°Bx). Upon production of wort without the addition of any enzymes for liquefaction or saccharification, the addition of 30% rice resulted in the highest soluble solid content (°Bx). Production of beer containing 10, 20, or 30% of either roasted or puffed rice showed that wort containing 30% puffed rice had the highest soluble solid content (15.4 °Bx) with good saccharification. The resulting beer likewise exhibited higher alcohol content (5.0-5.4%) than the beer that had roasted rice added, without the turbidity and with less bitterness. Therefore, rice puffing was considered a beneficial processing method to enhance rice saccharification and to facilitate both the production of fine quality beers and rice beer containing puffed rice.

Soybeans are one of the world's top five staple crops and a major source of plant-based protein. Due to their susceptibility to climate change, which can significantly impact grain production, the National Agricultural Science Institute is conducting research on crop phenotypes through growth analysis of various soybean varieties. While the process of capturing growth progression photos of soybeans is automated, the verification, recording, and analysis of growth stages are currently done manually. In this paper, we designed and trained a YOLOv5s model to detect soybean leaf objects from image data of soybean plants and a Convolution Neural Network (CNN) model to judgement the unfolding status of the detected soybean leaves. We combined these two models and implemented an algorithm that distinguishes layers based on the coordinates of detected soybean leaves. As a result, we developed a program that takes time-series data of soybeans as input and performs growth analysis. The program can accurately determine the growth stages of soybeans up to the second or third compound leaves.

When compare with blebectomy or bullaectomy simply and pleurodesis together in treatment of primary spontaneous pnevmthorax, the later has been realized as the method that can reduce the recurrent rate after surgical operation. Therefore, in this study, we compared the merits and demerits of the clinical result of chemical pleurodesis that use Talcum powder in pleurodesis and mechanical pleurodesis that use apical pleurectomy and analyzed the reappearance rate etc. Material and Method: The Pleurodesis through the apical pleurectomy and talc powder insufflation had been used as secondary procedure after blebectomy of spontaneous pneumothorax from January 1, 2000 to June 30, 2002. This study consisted of a retrospective review of 68 patients who were treated with apical pleurectomy, and 84 patients treated with talc powder insufflation. We compaired the apical pleurectomy and talc powder insufflation in terms of age, sex, cause of operation, number of used autosuture staple, tine duration of procedure after blebectomy, severity of pain and complication after operation, postoperative air leakage period, duration of chest tube insertion, hospitalization, and recurrence rate of pneumothorax. Result: Time required for secondary procedure was longer in apical pleurectomy than talc powder insufflation. Postoperative pain was more severe in talc powder insufflation than apical pleurectomy. Otherwise there was no significant difference between two methods. Conclusion: Although Talc powder insufflation is more convenient than apical pleurectomy, the difference is not large and, the severity of postoperative pain is worse in talc powder insufflation. Therefore apical pleurectomy can be recommended for the secondary surgical procedure after blebectomy of primary spontaneous pneumothorax can be recommended.

An engineering design of the machines and equipment for processing grain as well as an understanding of processing itself need the knowledge of thermal properties of grain. Thermal properties of grain are thermal conductivity, thermal diffusivity and specific heat. Knowledge of any two and the bulk density of grain enables the third to be calculated. Several workers have investigated these properties, with special emphasis on thermal conductivity and diffusivity. However, some information is available on the specific heat of rough rice and barley but it is available only for a foreign variety of grain and for as a function of moisture content only. The objectives of this study were to develop a model for the specific heat of rough rice and barley which were a staple products in Korea as a function of initial temperature, moisture content and porosity of grain with cooling curve method, and to analyze the effect of these factors on the specific heat of rough rice and barley. The results of this study are summarized as follows; 1. The specific heat was $1.8209-2.7041kJ/kg\;^{\circ}K$ for Naked barley, 1.8862-2.5625 k.l/kg K for Covered barley, $1.5167-2.3779kJ/kg\;^{\circ}K$ for Japonica rice and $1.5260-2.3981kJ/kg\;^{\circ}K$ for Indica rice. 2. The model for the specific heat of rough rice and barley as a function of initial temperature, moisture content and porosity of grain was developed. 3. Specific heat of rough rice was decreased with initial temperature, but specific heat of barley was increased with initial temperature. 4. On the whole specific heat of sample grain was increased with moisture content of grain. 5. Specific heat of the grain was found to decrease with porosity except Indica rice.
