The natural dyestuff(squid ink) was manufactured from squid ink by boiling in 0.1% NaOH solution and powdering in freeze dryer. Cotton, wool, silk and nylon fabrics were dyed under several conditions using the manufactured squid ink to investigate the dyeability and color fastness. Dyeing was operated in acidic dyebath of pH 4 because the squid ink is anionic. Dyeabilities on wool, silk and nylon fabrics were good, especially silk fabrics were dyed deeper than others because of being amine group. But dyeability on cotton fabrics was low and developed with chitosan treatment. All the dyed fabrics showed excellent in color fastness to crocking and laundering. Also light fastness of them were excellent except nylon. The light fastness of dyed-nylon fabrics was as poor as grade 1, but they could be improved to grade 4 by aftertreatment with gallicacid. Useing the natural dyestuff-squid ink powder, we could execute whenever we want to dye fabrics in the adequate concentration. Dyeabilities were developed according to repeating times of dyeing and the increased dye concentration. We could recycle the wasting sources.

Malignant fibrous histiocytomas (MFHs) is the most common type of soft tissue sarcoma in the old animal with a aggressiveness, a high local recurrence rate and significant metastatic rate, which associated with a poor prognosis. In most histologic and immunohistological studies, the tumor cells raised from a fibroblastic and/or myofibroblastic phenotype, presumably from undifferentiated mesenchymal cell origin. MFHs are usually firm and invasive, arising in the subcutis; metastasis depends on tumor grade (many are grade 3) [1,2]. The primary tumor cells are pleomorphic, varying in appearance from fusiform to round. Often nucleoli are prominent and irregular [5]. Extracellular amorphous eosinophilic material may be prominent and likely represents reactive collagen production by the tumor [5]. (omitted)

The natural dyestuff, grape skin dye was manufactured from grape skin by boiling in 0.1% HCI solution, eliminating the sugar and powdering in freeze dryer. Cotton, wool, silk and nylon fabrics were dyed under several conditions using the manufactured grape skin dye to investigate the dyeability and color fastness. Dyeing was operated in acidic dyebath of pH 4 because the grape skin is anionic. The color of dyed fabrics were affected on temperature of dyeing solution. Under 80$\^{C}$, the color of dyed fabrics were red or violet, but changed to brown in laundering. Above 100$\^{C}$, the color were brown and safe in laundering. Dyeabilities on wool, silk, and nylon fabrics were good, especially silk fabrics were dyed deeper than others. Dyeability was developed with concenturation of dyeing solution. All the dyed fabrics were excellent in color fastness to crocking and laundering. Light fastness was low to moderate. The light fastness of dyed nylon fabrics were as poor as grade 1, but they could be improved to grade 3∼4 by aftertreatment with gallic acid.

빈곤가구의 식품 미보장은 상대적으로 풍요로운 사회에서 경험되는 불평등과 사회적 박탈을 보여주는 중요한 현상이므로, 이 연구에서는 아동이 있는 수급 가구들의 '식품 미보장 경험'을 탐색하였다. 연구에 참여한 부모들은 제한된 소득 내에서 식품 구입을 위해 사용할 수 있는 자원의 부족으로 인해 적절한 혹은 충분한 양의 식재료 구입에 어려움을 겪고 있을 뿐 아니라, 질 낮은 식재료의 선택 및 사용, 상대적으로 보다 값싼 재료로의 대체, 이용가능한 식재료 종류(특히 육류와 과일)의 제한, 단조롭고 제한된 식사 구성과 같은 경험을 일상적으로 하고 있었다. 때로는 이로 인해 아이들이 식사를 거르기도 하였다. 즉 '식품 미보장'개념을 구성하는 내용들이 아동이 있는 빈곤 가구들에서 실제로 경험되고 있는 것으로 확인되었다. 하지만 식품 미보장 척도상에서 보고가능한 내용과 질적 면접을 통해 보고되는 내용에 어느 정도 차이가 있으므로 이러한 점이 향후 식품 미보장 척도를 활용함에 있어 충분히 고려되어야 할 것이라고 생각된다. 또 대부분의 가정에서 현재 이루어지고 있는 다양한 사회복지서비스들이 부분적으로 가구내 식품 미보장 상황을 보완해 주고 있는 점 등도 척도 활용시 고려되어야 할 점이라고 생각된다.

목적: 케모카인 수용체인 CXCR4는 암에서 발현되며 암의 전이에 관여한다고 알려져 있다. 저자들은 통상적인 조직학적으로 고등급인 골육종과 저등급 중심부 골육종에서 CXCR4 발현을 비교하고 CXCR4 발현과 예후 간에 연관성이 있는지 살펴보았다. 대상 및 방법: 총 63명의 골육종 환자에서 CXCR4에 대한 면역조직화학검사를 시행하였고 임상적, 병리학적 인자 및 전체적인 생존율과의 연관성을 살펴보았다. 결과: CXCR4는 통상적인 고등급(조직학적 등급 3 및 4) 골육종의 76.3%에서 발현된 반면 저등급(조직학적 등급 1 및 2) 중심부 골육종의 36%에서 발현되었다. 또한 고등급 골육종의 47.4%에서 미만성으로 발현된 반면 모든 저등급 골육종은 병소에 국한되어 발현되었다. CXCR4 발현은 조직학적 등급과 통계학적으로 유의한 상관관계를 나타내었다(p<0.0001). 전체적인 생존률은 CXCR4 발현 증가(p=0.0058), 고등급의 조직학적 등급(p<0.0001), 어린 연령(p=0.0140)에 따라 유의하게 감소하였지만, 성별, 종양 크기, AJCC 병기와는 연관성이 뚜렷하지 않았다. 결론: CXCR4 발현은 골육종에서 고도의 조직학적 분화도가 나쁜 등급 및 불량한 예후와 연관된다.

This study was done to investigate satisfaction of fifth-grade(n=264) and sixth-grade(n=117) students from school foodservice in five elementary schools in Won-ju. On a scale of 1 to 5, with 1 being very poor and 5 being very good, overall satisfaction from school foodservice was found to be 3.21$\pm$0.98('so-so$\sim$satisfaction'). The highest satisfactory factor was neatness of foodservice staffs(3.79$\pm$1.00), while the lowest satisfactory factor was the students' overall opinions of school foodservice(3.03$\pm$1.06). The biggest unsatisfactory factor was found to be 'bland food'. 'Enhancement of taste'(49.08%) caused the most complaints against school foodservice. Soup was identified as the type of food most likely to be left over, and there was some significant difference between fifth-graders and sixth-graders. The reason cited most often for leftovers was unfavorable menus(33.42%). Students were more likely to try foods which were unfamiliar to them and also foods they previously disliked as a result of using school foodservice(28.87%). Also significant, when the meal director was present during the meal service, satisfaction was markedly higher than when the director was not present.

Purpose:It has been known that the prognosis of a young woman's breast cancer is Poorer than the other woman However, the effect of age on the prognosis is not well-defined We performed this study to investigate age as a prognostic factor of breast cancer. Materials and Methods : A retrospective study was conducted for 3209 breast cancer patients who underwent operations in Department of Surgery, Seoul National University Hospital from January 1981 to December 2000. Patients were divided into two groups, young age(≤35) and old age(>35) groups. And tumor stage, histopathologic characteristics(such as histology, nuclear grade, histologic grade, hormonal receptor, etc), overall survival and disease free survival rates were compared between age groups. Results . The age ranged from 17 to 88 years. 396 patients(12.3%) were included in young age group(median=32) and 2813 Patients(87.7%) in old age group(median=47).There are more advanced stages and poor nuclear grades in young age group(p=0.000, p=0.003), By log-rank test, the young age group had poorer overall survival and disease free survival rates(p<0.05, p=0.0002). Although, the young age group had more advanced TMN stages(p=0.000) and poorer nuclear grade than the old age group(p=0.003) in multi variate analysis, the age was not a significant independent prognostic factor. (P=0.642)Conclusion: Our study showed that the age was not a significant independent prognostic factor.

The purpose of this study is to select appropriate location factors for wind power plant, provide detailed classification criteria, and find out appropriate sites for installing wind power plant in Gangwondo. In this study, the following 11 factors were extracted for site selection of wind power plant : wind resource, topography (valley angle, distance to the ridge), forest density, land use, preservation area, national park, Baekdu-Daegan, noise, shade, Transmission Line, and approaching roads. Each factor had relatively different level of importance so that AHP (Analytic Hierarchy Process) technique was used to calculated the weighted value per factor. For overlay analysis, classification criteria were prepared for each factor and each factor was classified into 3 grades : very appropriate, intermediate, poor. According to overlay analysis, the areas which received the highest grade (grade 5) was only in 0.16% of the total area of Gangwondo and had a tendency to exist along the mountain ridge over 600-meter elevation. Through analyzing the yearly average of wind power density, it was proved that the wind power density of areas with grade 4 or 5 had abundant wind resource over $400W/m^2$.

Background: Evidence indicates that Dickkopf-1 (DKK-1) levels may be a biomarker for cancer risk. The aim of this study was to assess DKK-1 and its correlation with clinic-pathological features in patients with bladder cancer. Materials and Methods: DKK-1 levels were determined in serum samples from 90 patients with bladder cancer before transurethral tumor resection. The concentrations of DKK-1 were determined by using enzyme linked immune-sorbent assay (ELISA). Results: Elevated preoperative DKK-1 levels were associated with tumor stage (p<0.001), grade (p<0.001) and histological grade (p<0.001). Conclusions: The results of our study demonstrated that the level of serum DKK-1 is correlated with both disease progression and increase in the tumor grade. Preoperative serum DKK-1 elevation may thus represent a novel marker for the determination of bladder cancer and the detection of patients with a likely poor clinical outcome.

Background: Triple negative breast cancers (TNBCs) are high grade aggressive tumors generally with a poor prognosis, not responding to hormonal and anti Her2 Neu therapy. Expression of the antiapoptotic B cell lymphoma 2 gene (Bcl-2) is associated with low grade, slowly proliferating hormone receptor positive tumors with improved survival. Anti Bcl2 agents can be used as alternative targeted therapy in triple negative cancers. Materials and Methods: The objective of this study was to determine the immunohistochemical expression of Bcl2 in triple negative breast cancers and any correlation with clinicopathological variables in Northern Pakistan. Results: All 52 patients were females, aged between 28 and 80 years(average $48.0{\pm}12.1$). 28 cases (53.8%) were positive for Bcl2, this being associated with low grade invasive ductal carcinomas, lymph node metastasis and lymphovascular invasion. Conclusions: Bcl-2 may be an important prognostic factor and its expression might be used for targeted therapy using Anti Bcl2 drugs.
