The period of the Fourth Industrial Revolution is our near future and the ongoing changes in this age. We need to strive to adapt to this changes and also try to create new values. This study focuses on workers' perceptions and attitudes (self-efficacy, expectancy, and acceptance of change) toward the Fourth Industrial Revolution. These positive attitudes toward the upcoming future and the Fourth Industrial Revolution will influence on both the future and the current attitude, behavior and performance of employees. People have certain attitudes to the future, and these attitudes have an impact on current behavior. This paper tries to examine the positive attitudes toward the Fourth Industrial Revolution era and the influence of positive attitudes toward this new age on the current job satisfaction. Through this process, this paper explains what kinds of attitudes the workers should have in the Fourth Industrial Revolution era, and also sheds light on significance and purpose of this paper to explain how these specific attitudes toward the future influence the present performance such as job satisfaction.

Children are not small adults and there is a need to carry out specific trials that cannot be performed in adults. In general, children (minors) are unable to consent but their assent should be obtained using age appropriate information. Institutional Review Board (IRB) need paediatric expertise to balance the benefits and risks of research in children. The lack of consent has implications on the design, analysis and the choice of comparators used in the trials, which should only be performed by trained investigators with paediatric experience. Pain, fear, distress and parental separation should be prevented and minimised when unavoidable. The children requires even more careful review. Children represent a vulnerable population with developmental, physiological and psychological differences from adults, which make age- and development- related research important for their benefit. Finally, criteria for the protection of children in clinical trials therefore need to be laid down. Specific protection should be defined for research performed in children, at all stages and ages.

Basic creep of concrete during very early ages is an important factor on the behavior of young concrete and a great deal of research has been executed. However, in recent studies, it was revealed that the basic creep measured by sealed concrete was inaccurate, especially for high strength concrete because of autogenous shrinkage at early age. This paper presents the results from experimental study that investigate to explore the effect of autogenous shrinkage in basic creep. More specifically, four different mix proportions were casted and the primary variables were water-cement ratios. Through this research, it was found that the differences between apparent specific creep and real specific creep were remarkable in low water-cement ratio at early age. Therefore, it is recommended to modify existing creep model by considering autogenous shrinkage

Recently, the demand for pubic welfare has been expended to the comprehensive services terms of cultural, medical and psychological aspects and provision of information. These various demands for welfare services to improve citizens'quality of life could be effectively met by an integrated community center covered small regions rather than many existing individual institutions focused on specific services covered wide regions. The purpose of this study was to develop the activity programs for a proposed new millennium community center The activity programs classified into five types (administrative services; information and counselling; health and sports; leisure and culture; and child care and educational services) and each type included various unique activity programs not only for specific age groups but also for all age groups. In order to operate a new millennium community center effectively, the legal supports and systematic organizations to manage the community center should be required. Discussions and recommendations for these issues were included in the study.

Cancer is a major health problem in the Arab region including Iraq. An adequate database is essential for effective cancer control strategies. Such a database may be provided through cancer registration but supportive household surveys may be useful. This article reports selected results on the feasibility of household surveys to support and validate cancer registration in Basrah governorate - southern Iraq. A large scale multi-stage cluster sample household survey was carried out in Basrah during 2013. It covered 6,999 households and involved gathering data on demographic characteristics and both incident cancer cases and cancer-related deaths among members of these households during a three-year recall period (2010-2012). The data obtained yielded an average annual incidence rate of 91 per 100,000 population (age-standardized incidence rate of 148.8 /100,000) and cancer specific mortality rate of 68 per 100,000 population (age-standardized mortality rate of 126.3/100,000). The results showed an overall pattern of cancer similar to that reported according to cancer registration but the household survey results were consistently higher than those of the cancer registration by a margin of approximately 20- 30% with respect to incident cancer and about 70 % with respect to cancer-specific mortality. Household surveys on cancer, while costly and time consuming, are a very useful additional source of information on cancer at the population level. They can be performed for specific purposes with effective resource mobilization.

Prostate cancer (CaP) is a common reproductive cancer among men. This study was conducted to correlate the cancer incidence with Gangetic zone and to correlate the tumor marker prostate specific antigen (PSA) level in serum with different age groups and stage of malignancy. Patients suffering from CaP in the pathology unit of Mahavir Cancer Sansthan (Hospital and Research Centre), Patna, Bihar, India were studied from June 2009 to May 2010. PSA level in the serum of CaP patients was estimated by ELISA method. CaP incidence was highly recorded in Gangetic zone than the non-Gangetic zone. Maximum patients were in the 56 - 75 years age group with a marked predominance. Results of PSA examination showed that serum PSA level was not correlating with the age of patient and stage of malignancy. Significantly, elevated level of more than 10 ng/ml of PSA was recorded among the studied cancer patients. In this study, it is concluded that Gangetic zone habitat have high risk of CaP and elevated level of PSA was marked in Bihar, India.

The purpose of this study was to determined the rate of sensitization to food allergen in children with Atopic Dermatitis (AD) in Korea. A total of 3,783 patients (male = 1983, female = 1800) with AD (age under 18 years) who had visited Samsung Medical Center from 1998 to 2003 were enrolled in the study. Food hypersensitivity was measured by specific IgE to egg, cow's milk, soy, peanut, wheat, buckwheat, beef, pork, chicken, shrimp, crab, salmon, mackerel, etc. Specific IgE levels > 0.7 kU/L. by Captured Allergen Product (CAP) assay were considered positive. Chi-square test at p value < 0.05 was used to examine the difference of the prevalence by sex and age. The rate of sensitization to multiple food allergens was 31.2% and decreased with age. Hypersensitivity to egg showed highest prevalence, which was 24.3%, compared to the prevalence of other foods. High prevalence of hypersensitivity to milk. wheat, soy, peanut, crab or shrimp was observed (11.6- 17.7%). Low prevalence of hypersensitivity to beef, pork, tuna or chicken was observed (1.9-3.5%). Children aged under 3 years had significantly higher prevalence of hypersensitivity to egg, milk, soy and beef than children aged at least 3 years. Our results stress the need for examination of food hypersensitivity aimed at identified and limited each food allergen among children with AD caused by food to help patients outgrow their food allergy.

The purpose of this study was to research specific dimensional increments of grading and to support to establish a grading system according to the targets of women's wear manufacturers in Korea. For the questionnaire, 91 women's wear brands, which were in higher ranking of sales, were selected, and the age groups were separated into 3: 20's, 30's, and 40's & 50's, according to their customers. The graders of each brand were questioned about specific dimensional increments of grading fur this research. The results of the study were as follows: 1. Using the most common dimensional increments, 3.81cm(1 f inch) and 5.08cm(2 inch) for upper garments and lower garments, the modes of increments and reference increments for each garment section were suggested. 2. For upper garments, the brands for older women made larger increments of waist girth than for bust girth. This was to cover abdominal obesity. Also, the brands made larger increments of girth than for shoulder breadth. 3. For lower garments, the brands for older women made larger increments of waist girth than fur hip girth. It meant the drop value of hip girth minus waist girth was smaller. The breadths of front and back crotch were also wider.

This article uses genealogical information to estimate fertility, mortality, and population growth in Korea during the eighteenth and nineteenth centuries. Upper class males' probability of dying as estimated from genealogies was converted into that for the whole male population drawing upon information on colonial mortality and model life tables, which indicated male life expectancy at birth was 23 years. Age-specific marital fertility rates for upper class females as calculated from genealogies were combined with estimates of age at first marriage and information on colonial fertility to derive age-specific fertility rate for the whole female population, which implied a total fertility rate of 6.81. Finally, the estimated indices of mortality and fertility were inserted into equations describing stable populations to find that the Korean population grew 0.62% p.a. during the eighteenth and nineteenth centuries.

Human body ages differently due to environmental, genetic and pathological factors. DNA methylation patterns also differs depending on various factors such as aging and several other diseases. The aging clock model, which uses these differences to predict age, analyzes DNA methylation patterns, recognizes age-specific patterns, predicts age, and grasps the speed and degree of aging. Aging occurs in everyone and causes various problems such as deterioration of physical ability and complications. Alzheimer's disease is a disease associated with aging and the most common brain degenerative disease. This disease causes various cognitive functions disabilities such as dementia and impaired judgment to motor functions, making daily life impossible. It has been reported that the incidence and progression of this disease increase with aging, and that increased phosphorylation of Aβ and tau proteins, which are overexpressed in this disease and accelerates epigenetic aging. It has also been reported that DNA methylation is significantly increased in the hippocampus and entorhinal cortex of Alzheimer's disease patients. Therefore, we calculated the biological age using the Epi clock, a pan-tissue aging clock model, and confirmed that the epigenetic age of patients suffering from Alzheimer's disease is lower than their actual age. Also, it was confirmed to slow down aging.
