The study investigated if IT investment in Korean financial markets for the past 18 years has grown following the s-curve pattern based on Nolan's growth model in order to find the correlation between IT investment and management performance in the financial industry. According to the research finding it can be said that the overall financial markets maintain s-curve pattern, and IT investment is related to management performance, particularly increase in total assets and net profit. However, each sector has defining features of growth patterns. The banking industry has grown similarly to the s-curve, and the insurance industry also shows the s-curve but it looks more like linear pattern. In terms of securities industry, its growth patterns can hardly be considered s-curve due to the irregular changes. his research outcome illustrates the analysis of IT growth patterns in the financial industry and thus, it is expected to be a useful reference when deciding the appropriate time for IT investment in the financial industry.

After the year of 2000, compositions of stock holders in domestic firms are rapidly changing. In domestic stock market, the proportion of market value held by foreign investors reaches over 40%. There are several blue chip companies among those where foreign investors hold more than 50% of the stocks. There are still hot debates going on about whether the increase in the number of foreign investors contributes to domestic companies. This research attempted to determine foreign ownership increases enhance firm value empirically. It has been shown that foreign ownership variable has significant positive impact on Tobin's Q of firm value variable. The result suggests that foreign ownership increases in domestic corporations positively contribute to firm value, as they monitor and keep the management transparent as an institutional investor, and they work to soothe agency problems by the managements or the large stock holders.

With dramatic transitions from a traditionally food-insecure to a food-sufficient society, over weight and/or obesity are an increasing health concern in Korea. In 2000, $35.9\%$ of Korean adults were over weight (BMI>25) with increasing trends. It is well known that obesity is highly correlated with chronic diseases, such as diabetes, hypertension, cardiovascular disease, cancer and high cholesterol. In 2003, the social cost of obesity is estimated at $529.5\~799.3$ billion won (direct cost) and at $1,200\~1,817$ billion won (including indirect cost). The share of the direct cost is estimated at $2.6\~3.9\%$ of total medical bill 20,742 billion won. These costs are underestimated and would surely be higher if the expenditures outside of the official medical insurance system of Korea were included. Based on the rapid increase of obesity rate among the Korean youth, it is crucial to develop and implement appropriate policies to curb the obesity epidemic.

The paper chooses the "Asian Financial Crisis" as a case study to examine its impact on Malaysian economy and describes how Malaysian government responded to the crisis. It also focuses on the Asian financial crisis' impact on the employment of banking sector in Malaysia. In the finance, insurance, real estate and business service sector, a number of 6,596 workers were retrenched. Banks were forced into mergers and acquisition as well as downsizing, trim lean, organizational changes and introduction of new technologies. Excess workers were offered a "voluntary separation scheme." These retrenched workers became the urban poor facing high cost of living and no opportunity for jobs as there is no safety net provided.

본 논문에서는 서비스업 종사자들의 감정노동에 따른 언어폭력의 실례를 파악하여 보고자 한다. 폭력은 외부로 가해지는 신체적 상해로 인지하고 있으나 언어폭력에 대한 인식은 상대적으로 미약하다. 외적으로 드러나는 상해가 아니어서 언어적 폭력의 강도는 더욱 심해지고 있으며, 자신의 감정 해소를 위한 수단으로 악이용되는 사례도 다분하다. 언어폭력이 미치는 영향 및 잘못된 인식 개선과 사회적, 제도적 대응 방안 마련 등 문제 제기를 통해 앞으로 심층적 연구를 하고자 한다.

This research put the point on deducing problems of our first-aid system and proposing improvement program. Now first-aid system has lots of weakness, such as short of speciality, limitation to raise finance. To improve these first-aid infrastructure must be expanded and improved, and it also needs enough effort for improvement of quality and arrangement of emergency medical treatment speciality. We should introduce commission to first-aid system so raise fund and make use of speciality. And also we should organize private partnership with hospitals or insurance companies, so that we can construct united system of first-aid system.

This study aims to investigate the levels of assets and debts that male- and female-headed households have in comparison to married-couple households. Toward this end, a series of analyses of data from the 2011 Korean Household Finance Survey on the assets and debts of single-parent households are conducted. The empirical results reveal that the amounts of assets and net worth of married-couple households were significantly larger than those of male- and female-headed households. A comparison between male- and female-headed households show that the latter were more likely to hold financial assets such as savings accounts, savings insurance and mutual funds. The amounts of assets of female-headed households were significantly larger than those of male-headed households. Furthermore, the amount of credit card debt in mele-headed households was significantly larger than that in female-headed households.

A step-up option is a newly developed financial instrument that simultaneously provides higher security and profitability. This paper introduces two step-up options: step-up type1 and step-up type2 options, and derives the option pricing formulas using the Laplace transform. We assume that the underlying equity price follows a regime-switching model that reflects the long-term maturity of these options. The option prices are calculated for the two types of funds, a pure stock fund composed of risky assets only and a mixed fund composed of stocks and bonds, to reflect possible variety in the fund underlying asset mix. The impact of changes in the model parameters on the option prices is analyzed. This paper provides information crucial to product developments.

It is the approach of development of teaching methods for competency development in business class. This study distinguishes areas that can be commonly applied to many business subjects. And we derive core competencies from the basic skills of NCS. The results of this study are as follows. First, we have established an opportunity to distinguish the subject field of business administration(personnel/organization/strategy, production/operation management, marketing, financial/finance/insurance, accounting, MIS). Second, we have proposed guidelines for the setting of the each subject goals and the setting of the professor's competency. Third, we have summarized teaching method which are studied as valid in business class(lecture method, problem based learning method, action learning teaching method, and management simulation teaching method) and we suggested how to apply teaching methods to the each subject.

The inclusion of covariates in the model often affects not only the estimates of meaningful variables of interest but also its statistical significance. Such gap between statistical and subject-matter significance is a critical issue in huge sample studies. A popular huge sample study, the sample cohort data from Korean National Health Insurance Service, showed such gap of significance in the inference for the effect of obesity on cause of mortality, requiring careful consideration. In this regard, this paper proposes a sample size calibration method based on a Monte Carlo t (or z)-test approach without Monte Carlo simulation, and also proposes a test procedure for subject-matter significance using this calibration method in order to complement the deflated p-value in the huge sample size. Our calibration method shows no subject-matter significance of the obesity paradox regardless of race, sex, and age groups, unlike traditional statistical suggestions based on p-values.
