인터넷은 정보의 바다로 불려 질 만큼 엄청난 정보를 가지고 있지만 개인정보를 수집하여 악의적인 행동을 하는 각종 웹사이트에 제공함으로써 개인정보 유출 뿐 아니라 경제적 손실을 야기할 수 있다. 현재의 정보기술은 인터넷뿐만 아니라 모바일이나 개인용 단말기에서도 정보를 얻을 수 있기 때문에 개인정보의 유출은 엄청난 속도로 퍼져나갈 수 있다. 따라서 웹페이지 상에서 개인정보는 개개인을 구별하는 기본적인 정보로서 그 중요성이 더욱 증가 되고 있는 반면 개인정보 유출로 피해 사례 또한 증가하고 있다. 따라서 본 연구에서는 웹상에서의 최근 개인정보 침해 사례와 그 원인 및 보호 방안을 검토 및 분석한다.

Nowadays, small- and medium-sized enterprises (SMEs) are placed among the key components of the economy in both developed and developing countries. They are internationally known as the driving force based on their enormous contributions to Gross Domestic Product (GDP) and generating new employment. They are generally presumed as the leader of environmental sustainability, economic prosperity, and innovation, particularly for the economy of developing countries such as Vietnam. However, SMEs have difficulty in raising capital, as well as access to credit. One of the reasons is that there are inadequacies in accounting information quality in SMEs as well as the provision of accounting information and accounting information confidentiality. The main objective of this study was to identify, evaluate, and measure the attributes of accounting information quality of SMEs in Hanoi. The study was based on a field survey using a semi-structured questionnaire on a sample of 150 accountants. The study has identified and measured six (6) attributes of accounting information quality of SMEs that have great effects on accountants. There is, statistically, no significant difference in the level of accounting information quality of SMEs in Hanoi from these different business areas. There is no, statistically, significant difference in the level of accounting information quality of SMEs in Hanoi between the mentioned three groups of the job description. Based on the findings, some recommendations are given for SMEs to improve accounting information quality.

The study examines the relationships among financial knowledge, financial management, and objective financial well-being and subjective financial satisfaction. The data used in the study was 331 households from the survey in both Seoul and Kyeonggi-Do. The data analysis was dome using the SAS-PC program and several statistical techniques were utilized such as frequency, and multiple regression analysis. The results of the study were as follows; The results from multiple regression analysis providing the information about the relationships between two variable after controlling other effects on the variables, showed that, the households with more financial knowledge tended to do more on both financial management plan and financial management implement. The households doing more on financial management implement were found to have more subjective financial satisfaction, while those doing more on financial management plan were found to have more objective financial well-being. Also, a positive relationship was found between objective financial well-being and subjective financial satisfaction.

Reliability in electrical power system refers to normal operation for schedule time in some system that action consists. It means that if there is no contingency of electric power supply decrease or load curtailment, reliability of the system is high. In this paper, a method for evaluation of transmission capability is proposed considering reliability standards. Deterministic and probabilistic methods for evaluation of transmission capability has been studied. These researches considered uncertainty of system components or N-1 contingency only. However, the proposed method can inform customers and system operators more suitable transmission capability. Well-being method using state probabilities of system components proves to be a more effective method in this paper comparing with calculation of LOLE(Loss of Load Expectation). The length of calculation is shorter but it can give more practical information to the exact system operators. Well-being method is applied to IEEE-RTS 24bus system to evaluate reliability in case study. The result is compared with a existing way to evaluate reliability with LOLE and it shows that transmission capability connected with adjacent networks. This paper informs system operators and power suppliers of reliable information for operating power system.

We analyzed the dynamics of the family system and the economic well-being by utilizing the socio-demographic, objective economic, and subjective economic factors of urban unemployed housewives. The survey was conducted in Seoul and three other major cities. The subjects included housewives in these areas who were currently cohabiting with their spouses and had at least one child. The preliminary and main survey questionnaires were distributed between November 12, 2001 and February 27, 2002. Three hundred five survey questionnaires were collected and analyzed. We applied the frequency, average, percentage, Pearson's correlation coefficient, Cronbach's, simple regression and multiple regression analysis by using SPSS/PC WIN. The findings were as follows. First, the mean score of the availability of life information was 3.21. Second, when the availability of life information increased, the dynamics of family system improved. Third, when the dynamics of family system worked well, the housewives experienced economic well-being.

Quorum sensing (QS) is a bacterium-to-bacterium cell communication mechanism allowing bio-cell network construction but such mechanism is not well defined yet. We construct a QS-based multiple access network (MAN) and then numerically analyse its average uplink channel capacity as well as BER performance over diffusion-based 3-D molecular communication channels.

Li and Mak (1994) developed a test statistic for detecting the non-linearity and the heteroscedasticity of the time series data. But it is well known that the test statistic may be very sensitive in case of heavy-tailed distributions of the errors. Jiang et al.(2001) suggested the robust method for ARCH models but the calculation procedures for the estimation are very complicated. We suggested the robust method based on Huber's function and our method works quite well rater than the Li and Mak(1994). Also our method is relatively easy to calculate the test statistic.

In this paper a new fading model is proposed, which is well consistent with the real environment of smart antenna applications since it is spatially and temporally correlated simultaneously. The new model(STCFM: Spatially and Temporally Correlated Fading Model) is derived statistically in spatio-temporal domain so that it can provide high accuracy in the evaluation of the smart antenna system. As will be seen, the simulation results agree well with the theory.

This paper presents a method for the identification of "edge observations" located on a boundary area constructed by a truncation variable as well as for the identification of outliers and the after fit of multivariate skew $t$-distribution(MST) to asymmetric data. The detection of edge observation is important in data analysis because it provides information on a certain critical area in observation space. The proposed method is applied to an Australian Institute of Sport(AIS) dataset that is well known for asymmetry in data space.
