The endowment and concession has been put to practical use for the relocation projects of military Facilities. Yet, in terms of the project implementation, delay of a great deal of the projects is occurring due to related regulations and standards, as well as a lack of mutual understanding between project implementers and military units. This study analyzes the risk factors by identifying and prioritizing the potential risk factors at each stage of project implementation such as the issues that limit project characteristics and implementation. Among the derived risk factors, request exceeding facility standards in the licensing and design phases, opposition to troop relocation in the project approval phase, design change during construction phase in the construction and completion phases, dissenting opinions on endowed/conceded property in the property disposal phase and absence of facility standards in the MOA conclusion phase were found to be the main object of consideration in risk management. This study is expected to provide project managers with a guideline for effectively pursuing the projects, as it provides prioritization and optimization of risk management.

Background: Breast cancer is known to be one of the most prevalent cancers among women in both developing and developed countries. The incidence of breast cancer in Pakistan has increased dramatically within the last few years and is the second country after Israel in Asia to have highest proportional cases of breast cancer. However, there are limited data for breast cancer available in the literature from Pakistan. Objectives: The study was conducted to bring to light the common clinical presentation of breast cancer and to evaluate the frequency of established risk factors in breast carcinoma patients and furthermore to compare the findings between premenopausal and postmenopausal women in Pakistan. Materials and Methods: A 6 months (from July 2012 to Dec 2012) cross sectional survey was conducted in Surgical and Oncology Units of Civil Hospital, Karachi. Data were collected though a well developed questionnaire from 105 female patients diagnosed with carcinoma of breast and analyzed using SPSS version 17. Institutional ethical approval was obtained prior to data collection. Results: Out of 105 patients, 43 were premenopausal and 62 were postmenopausal, 99 being married. Mean age at diagnosis was $47.8{\pm}12.4years$. A painless lump was the most frequent symptom, notived by 77.1%(n=81). Some 55.2% (n=58) patients had a lump in the right breast and 44.8%(n=47) in the left breast. In the majority of cases, the lump was present in upper outer quadrant 41.9% (n=44). Mean period of delay from appearance of symptoms to consulting a doctor was $5.13{\pm}4.8months$, from the shortest 1 month to the longest 36 months. Long delay (> 3 months) was the most frequent figure 41.9%. Considering overall risk factors most frequent were first pregnancy after 20 years of age (41%), physical breast trauma (28.6%), lack of breast feeding(21.9%), and early menarche <11 years (19%), followed by null parity (16.2%), consumption of high fat diet (15.2%), family history of breast cancer or any other cancer in first degree relatives (9.5% and 13.3%, respectively). Some of the less common factors were late menopause >54 years (8.6%), use of oral contraceptive pills (10.5%), use of hormone replacement therapy (4.7%),smoking (4.7%) and radiation (0.96%). Significant differences (p<0.005) were observed between pre and post menopausal women regarding history of physical breast trauma, practice of breast feeding and parity. Conclusions: A painless lump was the most frequent clinical presentation noted. Overall age at first child > 20 years, physical breast trauma, lack of breast feeding, early menarche <11 were the most frequent risk factors. Physical breast trauma, lower parity, a trend for less breast feeding had more significant associations with pre-menopausal than post-menopausal onset. Increase opportunity of disease prevention can be obtained through better understanding of clinical presentation and risk factors important in the etiology of breast cancer.

Esophageal achalasia is a disease with characteristic disorder of esophageal motility. Also, this disorder is known to be predisposing factor of malignancy. Although the incidence of esophageal cancer in patients with achalasia varies widely, the incidence hed been reported from l% to 29% in many articles. It is known that delay in management of achalasia is believed to increase the risk of malignant degeneration. We experience a case with esophageal cancer complicating longstanding esophageal achalasia.

The immature neonatal brain is susceptible to the development of seizures. Seizures occur in 1% to 5% of infants during the neonatal period. Neonatal seizures are most commonly associated with serious acute illnesses, such as hypoxic-ischemic encephalopathy, birth trauma, metabolic disturbances, or infections. Thus, newborn infants with seizures are at risk for neonatal death and survivors are at risk for neurologic impairment, developmental delay, and subsequent epilepsy. Experimental data have also raised concerns about the potential adverse effects of the currently used anticonvulsants in neonates on brain development. Therefore, in the management of neonatal seizures, confirmatory diagnosis and optimal, but shorter, duration of anticonvulsant therapy is essential. Nevertheless, there has been substantial progress in understanding the developmental mechanisms that influence seizure generation and responsiveness to anticonvulsants. The currently used therapies have limited efficacy and the treatment of neonatal seizures has not significantly changed in the past several decades, This review includes an overview of current approaches to the treatment of neonatal seizures.

Group buying is one of the most popular transaction patterns on the internet at least in Korea. Nevertheless, it is hard to find academic researches for it in view of consumer behavior. In this paper, we analyze factors which determine consumer's attitude toward and intention of participation in Internet group buying by comparison of Internet individual one. For this purpose, we propose “lowering price”, “decreasing risk” and “reducing transaction cost” as relative advantages and "lack of product assortment" and "delay of time" as relative disadvantages over individual buying on the Internet. For empirical test, Internet users who have some experiences of individual buying but not group ones on the Internet are surveyed and analyzed. In result, a satisfying model fitness for structural equation model is derived and most hypotheses except the relationship between "decreasing risk" and "attitude toward Internet group buying" are accepted. Our results provide not only academic contribution by suggestion of a research framework but also practical insight by discussion of diverse features in Internet group buying.verse features in Internet group buying.

Oral precancerous lesion is a morphologically altered tissue in which oral cancer is more likely to occur than is apparently normal counterpart. As dentists always do oral examination and dental treatment, with fundamental knowledge and attention of this lesion, it is relatively easy to find one. If followed by proper treatment and management, it is possible to minimize its oral cancer progression, or at least delay it. Even if it were to progress to oral cancer, very early detection is possible. However, no specific biomarkers are present at the moment that could reveal oral precnacerous lesion that is high risk of oral cancer progression. Since early detection of oral cancer followed by treatment could show good prognosis with just a simple ablative surgery. Dentists should also instruct people to avoid risk factor related oral cancer progression and take natural compound having anticancer effect. Hereby, As a primary care givers, dentists play an important role in prevention of oral cancer.

Recently, with the expanding market for electronic devices and electric vehicles, secondary battery usage has been on the rise. Lithium-ion batteries are particularly popular due to their fast charging times and lightweight nature compared to other types of batteries. A secondary battery consists of four components: anode, cathode, electrolyte, and separator. Generally, the positive and negative electrode materials of secondary batteries are composed of an active material, a binder, and a conductive material. Acetylene Black (AB) is utilized to enhance conductivity between active material particles or metal dust collectors, preventing the binder from acting as an insulator. However, when recycling waste batteries that have been subject to high usage, there is a risk of fire and explosion accidents, as accurately identifying the characteristics of Acetylene Black dust proves to be challenging. In this study, the lower explosion limit for Acetylene Black dust with an average particle size of 0.042 ㎛ was determined to be 153.64 mg/L using a Hartmann-type dust explosion device. Notably, the dust did not explode at values below 168 mg, rendering the lower explosion limit calculation unfeasible. Analysis of explosion delay times with varying electrode gaps revealed the shortest delay time at 3 mm, with a noticeable increase in delay times for gaps of 4 mm or greater. The findings offer fundamental data for fire and explosion prevention measures in Acetylene Black waste recycling processes via a predictive model for lower explosion limits and ignition delay time.

Background: The purpose of this study was to identify the risk factors influencing cognitive function and life satisfaction in elderly living alone. Methods: It was cross-sectional descriptive study by using secondary data from the 2014 national survey of Korean elderly. The study sample consisted of 2,249 subjects who live alone, aged 65 years old and over. Data were analyzed frequency analysis, ${\chi}^2$-test, t-test, ANOVA and Logistic regression analysis. Results: The risk factors that significantly influenced cognitive function were old age, bereavement, lack of education, no regular exercise and low socio-cultural activity satisfaction. The risk factors that significantly influenced life satisfaction were no bereavement, lack of education, no work, negative evaluation of health status, diagnosis of depression and no regular exercise. Also experience of emotional and economical abuse, neglect of financial support and low cognitive function were identified risk factors of life satisfaction. Conclusions: The elderly living alone with risk factors of cognitive decline should be interested. To prevent or delay cognitive impairment, regular exercise and socio-cultural activities were recommended. It was suggested that the promotion of cognitive function, appropriate work and exercise, and social efforts to prevent abuse and neglect can contribute to improving life satisfaction of elderly living alone.
