The pacific oyster Crassostrea gigas has a desirable taste and flavor that differs from those of other fish and shellfish. In order to develop a high value-added product from individually quick-frozen oyster extract (IQFOE), we prepared an oyster granular flavor seasoning (OGS) from IQFOE and characterized its qualities. The OGS was prepared by granular molding and fluidized bed drying with inosine monophosphate (IMP, 0.1%), yeast extract powder (1.4%), tangle extract powder (0.6%), monosodium glutamate (MSG, 5.0%), microcrystalline cellulose (0.6%), lactose (27.5%), salt (33.0%), spray-dried IQFOE (22.5%) as a powdered materials, and IQFOE ($Brix\;25^{\circ}$, 7.0%), soy sauce (0.4%) and water (1.7%) as a liquid materials. The moisture, crude protein, pH and salinity of the OGS were 3.4%, 12.5%, 6.50 and 32.0%, respectively. Especially, the OGS revealed very higher amino-N content (1,856.0 mg/100 g) than that (1,291.2-1,610.2 mg/100 g) of other commercial flavor seasonings. In taste-active compounds, free amino acid contents was 1,359.0 mg/100 g, and major ones were glutamic acid, taurine, hydroxyproline, glycine, lysine, phosphoserine, proline in order. And OGS showed good organoleptic qualities for taste, odor and general preference compared with commercial flavor seasonings on a local market.

Objective : The incidence and prevalence of spinal metastases are increasing, and although the role of radiation therapy in the treatment of metastatic tumors of the spine has been well established, the same cannot be said about the role of stereotactic radiosurgery. Herein, the authors present a systematic review regarding the value of spinal stereotactic radiosurgery in the management of spinal metastasis. Methods : A systematic literature search for stereotactic radiosurgery of spinal metastases was undertaken. Grades of Recommendation, Assessment, Development, and Education (GRADE) working group criteria was used to evaluate the qualities of study datasets. Results : Thirty-one studies met the study inclusion criteria. Twenty-three studies were of low quality, and 8 were of very low quality according to the GRADE criteria. Stereotactic radiosurgery was reported to be highly effective in reducing pain, regardless of prior treatment. The overall local control rate was approximately 90%. Additional asymptomatic lesions may be treated by stereotactic radiosurgery to avoid further irradiation of neural elements and further bone-marrow suppression. Stereotactic radiosurgery may be preferred in previously irradiated patients when considering the radiation tolerance of the spinal cord. Furthermore, residual tumors after surgery can be safely treated by stereotactic radiosurgery, which decreases the likelihood of repeat surgery and accompanying surgical morbidities. Encompassing one vertebral body above and below the involved vertebrae is unnecessary. Complications associated with stereotactic radiosurgery are generally self-limited and mild. Conclusion : In the management of spinal metastasis, stereotactic radiosurgery appears to provide high rates of tumor control, regardless of histologic diagnosis, and can be used in previously irradiated patients. However, the quality of literature available on the subject is not sufficient.

A study was conducted on four crossbred bulls, used as artificial insemination (AI) sires, to correlate their semen quality with their non return rate (NRR). Semen was collected once a week via an artificial vagina, diluted in egg yolk-citrate and maintained at $+7^{\circ}C$ for three days. It was evaluated for sperm motility, viability, morphology immediately after collection and was examined daily for sperm motility, viability and morphology of acrosome, mid piece and tail for a total of three days. A total of 2016 cows were inseminated by two AI technicians. The proportions of sperm with normal heads were 83.4% (63.7~91.7%), the proportion of spermatozoa exhibiting normal morphology (acrosome, mid piece and tail), motility and viability were 89.2% (82.3~92.0%), 71.3% (61.7~75.0%) and 76.7% (65.7~85.0%), respectively in fresh ejaculates. Sperm motility and sperm viability was significantly ($p$ <0.05) lower in Holstein-Friesian ${\times}$ Local bull than in other bulls during all three days of storage. The overall NRR for four bulls was 82.7% (72.9-87.5%). Bulls with higher sperm motility, viability and normal morphology of spermatozoa of individual bull had significantly (each $p$ <0.05) higher NRR. The highest ($p$ <0.01) NRR (87.5%) was observed in a Red Chittagong bull whose semen qualities were significantly ($p$ <0.05) higher than Holstein-Friesian ${\times}$ Local bull (NNR 72.9%). The results of the present study concluded that NRR at 56 days post AI is related to parameters of semen quality. Therefore, semen evaluation may allow the discarding of bulls with poor fertility in an AI program.

The aim of this study is to build an architectural landscaping design ways of vulnerable community in rural area. I surveyed scenery structures, public buildings and single home forms, and fence types of house in twelve villages which have undertaken improving environment of rural community in four provinces. They all have an inferior surroundings to live in rural village, because they were isolated from the city, located on the mountain or island, and made a living under the slate materials of roof. The central government has been driving to reform the conditions with local office, so that they may increase their living qualities and village environment to get to the general level of rural area. There are three results of this study as follows: First, the scenery of the village surveyed has a remarkable views of locality and hierarchy of layers between field and mountain, which is very identified as a typical image of Korean rural topology. Second, the public buildings and single homes and outside wall of houses were personally designed or reformed as a various types like a flat slab style and different architectural structure, because they followed only to keep the architectural code rather than to make a harmony with other traditional style buildings. When they have to remodel it again through SaethulMaul project, they are needed to consider of both architectural code and design guideline for the local landscape design image. Third, to make a different landscape view of each village and improve housing conditions, it should be taken a people participation design way.

본 논문은 비지역적(non-local)방법에 기반한 적응적 디노이징 방법을 제안한다. 비지역적 알고리즘은 부가적 백색 잡음(additive white Gaussian noise, AWGN)을 제거하는데 효과적이다. 노이즈 제거를 위해 비지역적 방법을 적용할 때 노이즈 수준에 따라 디노이징 파라미터가 조절될 필요가 있었다. 그러므로, 제안하는 방법은 입력 노이즈 수준에 따라 최적의 디노이징 파라미터를 제공하는 것이다. 제안하는 방법은 크게 두 가지 부분으로 나뉜다. 첫 번째로는 오프라인 과정과 온라인 과정이다. 오프라인 과정에서는 노이즈 수준과 디노이징 파라미터 간의 관계를 비지역적 기법을 이용하여 분석해본다. 다양한 디노이징 파라미터들이 비지역적 알고리즘에 적용되며 이에 대한 이미지이에 대한 이미지의 퀄리티를 분석하기 위해서 SSIM 지표가 사용된다. 주어진 노이즈 수준에서 최적 디노이징 파라미터를 가장 높은 SSIM일 때 선택한다. 온라인 과정에서는 노이즈 수준을 실 시간으로 추정하여 최적의 디노이징 파라미터를 적용하여 비지역적 필터링을 수행한다. 실험 결과에서 보는 바와 같이, 제안하는 방법은 정확하게 노이즈 수준을 추정했고, 이미지 디테일을 보존하면서 AWGN 노이즈를 제거했다. 이에 따른 실험 결과로 노이즈 추정 정확도는 90.0%, 복원된 이미지에서 높은 PSNR과 SSIM수치를 보였다.

주상복합 아파트는 고급화와 다양한 장점으로 꾸준히 수요가 증가하여 수도권을 중심으로 지속적으로 공급되어 왔다. 지방중소도시의 경우에는 선례도 부족하고 성공을 담보할 수 없어 주상복합 아파트의 공급이 거의 이루어지고 있지 않았다. 현재에는 소득수준이 높아진 지방중소도시에 주상복합 수요가 있으며, 수도권 주택 공급이 포화된 현실에서 새로운 사업으로써 지방중소도시 주상복합 아파트의 공급 사업을 고려할 수 있다. 그러나 사업성의 타당성 분석을 위한 지방중소도시 주택 시장의 기본적인 자료나 관련한 연구가 거의 없는 실정이다. 이에 타당성 분석의 기초가 되는 적정 분양가격을 과거 시장가격이 없는 경우에도 적정가격을 추정할 수 있는 PSM 모델을 활용하여 추정하였다. 더불어 이러한 분양가격과, UTP를 통한 가격의 수요 탄력성, 가격결정 요인을 일반 아파트와 주상복합 아파트의 두 경우로 구분하여 각각 도출하고 시사점을 제공하고자 하였다. 분석결과 OPP 기준으로 봤을 때 주상복합 아파트의 분양가가 일반 아파트의 분양가에 비해 10.8% 높게 추정되었다. UTP도 주상복합 아파트가 높은 것으로 나타났으며 일반아파트 보다 주상복합 아파트의 가격민감도가 낮은 것으로 나타났다. 가격결정 요인 분석 결과는 일반 아파트와 주상복합 아파트 모두 응답자 연령, 교육수준이 유의한 것으로 나타났으며 주상복합 아파트의 경우 가족 수도 유의한 것으로 나타났다. 연구의 결과를 통해 실무적으로 활용이 가능한 분양가 추정 방법의 제시 뿐만 아니라, 지방중소도시에 주상복합 아파트를 공급할 경우 기존의 일반 아파트에 비해 높은 가격으로 분양가를 산정할 수 있다는 사실을 확인하였다. 더불어 수요탄력성이나 가격결정 요인 등의 결과를 주택 상품 기획을 위한 마케팅 분야에도 활용을 기대할 수 있다.

A cross-sectional study involving 400 mothers was conducted in the Manya Krobo district of Ghana with the objective of studying household dietary practices, quality of diets and family nutritional status of rural Ghana, A combination of methods, including structured interviews using questionnaire, dietary assessments and anthropometry was used to collect data for the study. The data obtained was analyzed using Statistical Package for Social Sciences (SPSS) Version 10 in Windows. Means and standard deviations were generated for continuous variables and frequency distribution for categorical variables. Most women consumed meals three times a day but only a few (12.5%) cooked all three meals at home. Breakfast and lunch were the two main meals purchased from food vendors. The most frequently consumed food items on daily basis were the starchy staples, maize, fish, pepper, onion, tomato and palm fruits. The nutritional qualities of diets were poor in terms of calcium and the B-vitamins. A significant proportion of the women were nutritionally at risk of being either underweight (12%), overweight (17%) or obese (5%). For adequate nutrition in this population, nutrition education intervention programs aimed at improving nutrient intake through improved diet diversity and increased use of local foods rich in calcium and the B-vitamins needs to be undertaken. There is also the need to intensify education on excessive weight gain and its attendant health problems in the area.

This study was conducted to compare the meat qualities of loin (m. longissimus dorsi) and top round (m. semimembranosus) from Hanwoo and Holstein veal. Ten Hanwoo and Holstein calves were randomly selected from a local cattle farm and raised. They were slaughtered when they were 8 mon old and weighed. Weight and percentage in primal cuts and slaughter performance of Hanwoo and Holstein veal calves are obtained. Immediately after weighting, slices of loin and top round muscles were sampled. After vacuum packaging, the samples were subjected to proximate composition, physicochemical and microbiological analyses. Dressing weight and percentage were heavier and greater (p<0.05) in the Holstein than in the Hanwoo. Water contents of the top round muscle was higher in the Holstein than in the Hanwoo (p<0.05). Water-holding capacity, protein content and CIE L* (lightness) of both muscles were higher in the Holstein than in the Hanwoo veal, whereas fat content, pH, cooking loss, a* (redness), and b* (yellowness) were higher in the Hanwoo than in the Holstein veal (p<0.05). Thiobarbituric acid and volatile basic nitrogen values of both the muscles were lower in the Hanwoo than in the Holstein veal during the first 10 d of storage (p<0.05).

Food Culture is formed in a unique culture heritage in some areas harmonized with social factors mixed with geographical conditions, natural environment, culture and religion. The more the life skill develops highly, the more people focus on improvement of the life skill in order to realize a delightful and convenient life, and plan an increase of production. Recently food-service companies have changed very quickly with economic environment. Such change will be continued and its speed will be more faster than now. Many food-service companies will disappear for weak competition, if they don’t manage adequately in such a case. Therefore, food-service companies have to search for an efficient, unique and creative management strategy. In such a viewpoint, Kyunggi-do designated five local cities as a model of Food Culture Streets greeting Welcoming Year of Kyunggi-do in 2005. The purpose of this study is to serve the healthy food to visitors visiting the Food Culture Streets and to do public relations about the excellence of their traditional food. In addition, this study includes improving tastes and qualities of food through education about cooking skills, management strategies and the best service with unique and creative menu development. Accordingly, we need to analyze the factors continuously on the business of food culture streets, and intend to use them as a database for high quality education and activity of food service industry in the future.
