Background: Breast cancer is the most prevalent malignancy among women with wide differences in clinical profile from region to region. The present study aimed to describe the profile of breast cancer patients attending a tertiary care hospital in Marathwada region of Western India. Materials and Methods: In this descriptive retrospective study, we reviewed records of pathologically diagnosed patients of breast cancer managed at our center from years 2009 to 2015. Data with respect to demographic status, detailed past, medical, familial and personal history, findings of clinical examination and histological features were obtained. Patients were staged according to the Tumor Node Metastasis (TNM) system. Results: Among 260 cases, mean age of presentation was 52.6, with average age of menarche of 11.3 and menopause of 52.6 years. The majority of patients were from urban regions and were postmenopausal (64.3%). Main clinical features presentation were breast lumps. Most patients were in stage II and had infiltrating duct carcinomas. Conclusions: Most common risk factors for breast cancer observed are increasing age, low parity and obesity. Breast cancer was more prevalent among postmenopausal women presenting in stage II with infiltating duct carcinoma in our region of India.

In this study, we evaluate the efficiency of Construction Industry using Data Envelopment Analysis(DEA). Since the Construction Industry has been traditionally operated through competition, it is important to measure the efficiency. In this paper, we empirically analyze the Efficiency of the 50 Korean Construction Industry. In detail, we used the scale of efficiency in order that efficiency cannot be affected by the total technical efficiency of each company and the scale of DMU by applying CCR or BBC model. Also, we analyzed the changes of measurement DEA model score. we adopted the basic DEA, RTS Region and MPSS(Most Productive Scale Size) method which are combined with efficiency measurement model in order to analyze the operational status. Furthermore, by complementing the shortfalls of the scale efficiency value of the DEA Model, RTS Region Model can be recommended to be appropriate in the evaluation of ideal input/output Quantity. In particular, input variables are total assets, construction capacity, the technical staff and output variables are sales volume, operating income. The result of RTS Region and MPSS shows that 9 DMUs of the efficiency frontier in the Construction Industry are analyzed to be relatively efficient DMUs, and 41 DMUs are analyzed to be inefficient DMUs, and finally inefficient DMUs are separated with Region 1 and Region 6.

Rural area development projects are being carried out in a strategy to create new value in agriculture and farm villages and to change the public perception. This study targeted rural experience participants visiting Cheong-Ho region, where the Rural Village Comprehensive Development Project was carried out. They were surveyed about attributes of visits to farm villages to determine which attributes of the experience could influence their revisits. This study was conducted under an umbrella project conducted as per the Special Act on Life Improvement and Regional Improvement for Farmers and Fishermen. Cheong-Ho region in Buan-gun produces mulberry, organic wheat, and rice grown using environmentally-friendly agricultural practices. This region as held events offering visitors the chance to experience rural villages and mulberry farms. Survey results showed that the natural landscape of villages, village experience, and the services provided by residents had a positive relationship with the probability of revisiting the village. Also, village facilities, harmony of natural landscape, hospitality of village residents, amusement value of rural experience, and the cost for rural experience were significant attributes. Therefore, it is necessary to revitalize the rural experience program targeting rural experience participants in Cheong-Ho region through continuous and monitoring of key visit attributes and revisit factors.

In the present study, velocity profile and wall shear stress distributions of developing turbulent oscillatory flows in an oscillator connected to straight duct located in exit region of a curved duct was investigated experimentally. The experimental study for air flows was conducted to measure axial velocity profiles, shear stress distributions by using the Laser Doppler Velocimetry(LDV) system with the data acquisition and processing system of Rotating Machinery Resolver(R.M.R) and PHASE software. The results obtained from experimental studies are summarized as follows. The critical Reynolds number for a change from transitional oscillatory flow to turbulent flow was about 7500, in the 60region of dimensionless axial position which was considered as a fully developed flow region. The turbulent oscillatory flow, velocity profiles of the inflow period in the entrance region were gradually developed, but those of the outflow period were not changed nearly. Velocity profiles of inflow and outflow were shown as a symmetric form in a fully developed flow region. The wall shear stress distributions of turbulent oscillatory flow increase rapidly as the flow proceeds to downstream and flow was in good agreement with the theoretically.

The aim of this study was to report a successful pregnancy using completely immotile frozen-thawed spermatozoa selected by laser. A single laser shot was used to detect the presence of viable immotile spermatozoa in fresh and frozen-thawed testicular spermatozoa. The viability rate was 55.8% after the laser detection, and cryopreservation was carried out immediately. The thawing test was performed on the day of oocyte pick-up, and no motile sperm were observed after extending the culture for another 4 hours, while a survival rate of 39.8% was detected using the laser. In all, five mature oocytes were injected, resulting in four cases of normal fertilization (80%) on day 1. Further, two high-quality day 3 embryos were transferred, which resulted in a singleton pregnancy. Our study demonstrates that completely immotile spermatozoa are worth cryopreserving for further intracytoplasmic sperm injection, which provides a new insight into male fertility preservation in cases of completely immotile spermatozoa.

The purpose of this study was to evaluate airborne concentrations and characteristics of TSP, IPM, TPM and RPM in Seoul subway stations. Sampling was performed at 14 stations from April 11 to 29, 2002. Size-selective dust concentrations and metal concentrations were measured by gravimetric method and ICP-AES, respectively. The geometric mean of TSP, IPM, TPM and RPM concentrations in Seoul subway stations were 176$\mu\textrm{g}$/㎥, 348$\mu\textrm{g}$/㎥, 158$\mu\textrm{g}$/㎥ and 104$\mu\textrm{g}$/㎥, respectively. Dust concentrations in pathway were the highest and those in lobby were the lowest. The size distribution of dusts was significantly different by location of collection. When the deposition rate into pulmonary gas exchange region was estimated by size distribution, the deposition rate of dust collected from platform was higher than those of dust collected from lobby and pathway. The lower the basement levels were, the higher the deposition rates of dusts into tracheobronchial region and gas exchange region were. Copper and iron concentrations measured in platform higher were than those in other areas.

This research was investigated to examine the status of goundwater contamination in Chung-Nam area over 2 years from 1996 May to 1998 May. The results show that the overall detection rates of VOCs (volatile organic compounds) by region were as followed: industrial region > agricultural & industrial complex region > gas station region > around industrial region > downtown region, and excess rates of those were as followed: industrial region > gas station region > agricultural & industrial region > around industrial region > downtown region. Benzene and TCE of VOCs examined in Chon-An industrial region exceeded drinking water standard. At the agricultural & industrial complex region, the observed mean concentration of TCE was 3.107 mg/L and TCE was also detected at 48.152 mg/L which is 100 times higher than drinking water standard, and other VOCs were also observed at higher concentrations as well. Based on our studies, It is concluded that appropriate remedial action should be performed to protect further groundwater contamination and to restore groundwater quality in Chung-Nam area.

This study examined the nutrient composition and taste properties of Sargassum fusiforme (SF) from two locations in the Wando region (Wando-eup: WD-A, Sinji-myeon: WD-B) and control region in Korea. The protein content of the SF in Wando regions was higher than that of the control, while the carbohydrate content was lower. The WD-A region had the lowest calorie content and the highest ash level when compared to the other regions. The potassium, iron, and zinc contents of the in WD-A were significantly higher than the other groups, but the sodium, phosphorus, and magnesium contents were lower. Free and constitutive amino acids, as well as the total and essential amino acid content, were higher in Wando regions than in the control. When analyzing using an electronic tongue, the SF from the WD-A region had the highest umami and sourness and the lowest bitterness and sweetness. Therefore, the results of this study can serve as fundamental data for seaweed research in the Wando region.
