A study on the subjective symptoms of the ageing process in middle-aged men: effects of socio-economic status,diet and health care behaviour*

In order to investigate the factors influencing the ageing process of middle-aged men, different environmental variables including socio-economic status, diet, smoking and drinking were studied as possible determinants of the ageing process. Six hundred and forty-seven Korean men over 40 years of age were studied. Frequency, chi-square, t-test, and stepwise multiple regression analyses were employed to identify the significant variables. As a result of the analyses, occupation and smoking were found to be the most influential factors. In short, those who did not refrain from smoking and had professional jobs experienced early symptoms in the ageing process.

关于分散系统管理的移动模式的设计

本文认为,随着通讯技术的迅速发展,对于大规模分散系统管理的要求越来越高,因为这样的系统组成要素是不均匀或是异质性的,而且各个组成要素都会形成不同的信息,管理时会生成大量的项目输送量。为了有效地管理大规模分散系统,需要对发生项目进行过滤,并相机变换管理系统,增强其扩张性和减轻网络系统的负担。为此而进行的在分散系统基础上使用移动agent的研究,设计能够有效地移动agent的移动模式,协调以前移动agent的移动方法与应答提案方法之间的关系。     

Willingness to Pay for Non‐biotech Foods in the U.S. and U.K.

This study uses closed‐ended and payment card formats to elicit willingness to pay for breakfast cereals made from non‐biotech ingredients. U.S. consumers were willing to pay a 10%∼12% premium to avoid biotech breakfast cereals, whereas U.K. consumers were willing to pay a 19%∼35% premium. Risk perceptions about agrobiotechnology proved to be an important factor shaping willingness to pay a premium for non‐biotech breakfast cereals. If consumers perceived risks to human health or environments from the use of biotechnology in crop/food production, or affiliated biotech foods unfavorably with morality or multinational corporations, they were more likely to pay a premium. Conversely, if consumers associated agrobiotechnology with various benefits (i.e., reduction in chemical use in crop production, mitigation of world food shortages, and improved nutritional content), they were less likely to pay a premium.     

Dairy product consumption in South Korea

The per capita daily consumption of dairy products increased approximately 2450% in South Korea from 1969 to 1987. The purpose of the present study was to determine the frequency with which urban South Koreans consume 10 common dairy products, and to find the socio-economic group most responsible for the increase in dairy product consumption. Data were collected on the dietary patterns and socio-economic backgrounds of 923 women, 880 children and 772 men in urban areas. This study showed that seven of 10 dairy products investigated were consumed evenly by both sexes, all age groups and income levels. However, three recently-introduced products (i.e. cheese, ice cream and butter) were found to be consumed most frequently by young Koreans in the high income level.     

The Distribution of Target Ownership and the Division of Gains in Successful Takeovers

This paper presents evidence that the distribution of target ownership is related to the division of the takeover gain between the target and the bidder for a sample of successful tender offers. In the whole sample, the target's gain is negatively related to bidder and institutional ownership. In the sample of multiple-bidder contests, the target's gain increases with managerial ownership and falls with institutional ownership.     

The JOBS Act and the Costs of Going Public

We examine the effects of Title I of the Jumpstart Our Business Startups Act for a sample of 312 emerging growth companies (EGCs) that filed for an initial public offering (IPO) from April 5, 2012 through April 30, 2015. We find no reduction in the direct costs of issuance, accounting, legal, or underwriting fees for EGC IPOs. Underpricing, an indirect cost of issuance that increases an issuer's cost of capital, is significantly higher for EGCs compared to other IPOs. More importantly, greater underpricing is present only for larger firms that are newly eligible for scaled disclosure under the Act. Overall, we find little evidence that the Act in its first three years has reduced the measurable costs of going public. Although there are benefits of the Act that issuers appear to value, they should be balanced against the higher costs of capital that can occur after its enactment.     

Fast-food consumption in South Korea

The consumption of fast-food products in Korea has undergone a rapid increase over the past ten to fifteen years. The aim of this study was to determine the frequency with which South Koreans consume seven common Western-style fast-food products and five common Korean-style fast-food products, and to find the socio-economic group most responsible for the increase in fast-food consumption. Data were collected on the dietary patterns and socio-economic backgrounds of 1,745 subjects between the ages of 12 and 64 years in urban and rural areas of Korea. This study showed that the fast-food products investigated were consumed mainly by Koreans under the age of 30, single, female, residents of Seoul, and either presently students or young adults with only grade school education. However, the results indicated that the consumption of most fast-food products was distributed amongst all income levels.
