Objective: The purpose of this study was to confirm difference between angular foot movement time and existing foot Fitts' law predicting times, and to develop the angular foot Fitts' law in the foot tapping task. Background: Existing studies of foot Fitts' law focused on horizontal movement to predict the movement time. However, when driving a car, humans move their foot from the accelerator to the brake with a fixed heel. Therefore, we examined the experiment to measure angular foot movement time in reciprocal foot tapping task and compared to conventional foot Fitts' law predicting time. And, we developed the angular foot Fitts' law. Method: In this study, we compared the angular foot movement time in foot tapping task and the predicted time of four conventional linear foot Fitts' law models - Drury's foot Fitts' law, Drury's ballistic, Hoffmann's ballistic, Hoffmann's visually-controlled. 11 subjects participated in this experiment to get a movement time and three target degrees of 20, 40, and 60 were used. And, conventional models were calculated for the prediction time. To analyze the movement time, linear and arc distance between targets were used for variables of model. Finally, the angular foot Fitts' law was developed from experimental data. Results: The average movement times for each experiment were 412.2ms, 474.9ms, and 526.6ms for the 89mm, 172mm, and 253mm linear distance conditions. The results also showed significant differences in performance time between different angle level. However, all of conventional linear foot Fitts' laws ranged 135.6ms to 401.2ms. On the other hand, the angular foot Fitts' law predicted the angular movement time well. Conclusion: Conventional linear foot Fitts' laws were underestimated and have a limitation to predict the foot movement time in the real task related angular foot movement. Application: This study is useful when considering the human behavior of angular foot movement such as driving or foot input device.

Many studies on the relationships between mothers-in-law and daughters-in-law tended to regard the relationship as a conflicting one. This study, unlike the previous ones, aimed to explore the relationship as it is and to describe the experience of the real relationship. Another aim of this study, on the basis of the results, was to provide the basic data for social services to develop and maintain the positive relationships between mothers and daughters-in-law. To achieve these aims, the central question of the study was, "What are the daughters-in-law's experiences with their mothers-in-law like?" The participants for the study consisted of 12 daughters-in-law who volunteered to be interviewed. Data were collected through in-depth interviews and analyzed according to the grounded theory presented by Strauss and Corbin. As a result, 154 concepts and 42 sub-categories were induced, and finally 18 categories were induced in the course of classifying and integrating these sub-categories. This study discovered that the relationship might be both positive and negative, and that it might even be possible to change from one to the other. The results of the study showed that many factors influenced the quality of the relationship, and that the husband's role was one of the most important factors. Using this study's results as guidance, general programs designed to cultivate more positive relationships between mothers and daughters-in-law can be created and implemented; additionally programs that help the husbands understand the complex relationship and roles can be devised.

Because Korea has the excellent informational technology, it was expected to be able to improve the accessibility to healthcare and compete with other nations in excellence through u-Healthcare. But we can't complete the excellent u-Healthcare because of the law to be able to use only the tele-counselling between doctor to doctor or doctor to nurse. First of all, we must complete the law to be able to use the improved u-Health containing of telemedicine between doctor to patient. Though other factors, the procurement of safe IT, the credibility to healthcare service provider containing of nutritionist and occupational therapist etc. are prepared for erecting u-Healthcare, we can get the final and decisive u-Health policy only by means of Law for supporting u-Healthcare's Activation. The important sections of Law for supporting u-Healthcare's Activation are as follows. Sec. 4 The Minister for Health, Welfare and Family Affairs and the dean of associated administrative division have to erect the combined plan for u-Healthcare's Activation. Sec. 11 Government and local autonomous entity can support the facility and equipment to be necessitated for using u-Healthcare to improve the medical accessibility of person in the region with poor medicine. Sec. 13 Doctor can support other doctor's medical action through IT and if there are not medical risk, doctor can give medical act directly to the special patients. Sec. 21 If pharmaceuticals is necessitated in u-Healthcare, remote doctor has to send the patient the electronic prescription and the pharmaceutist to receive the electronic prescription has to delivery the pharmaceuticals in accordance with patient's demand.

This study is designed to find out the determinants of housewives' caregiving behavior to their elderly parents-in-law. For this purpose, a tentative path model, constructed with major socio-demographic variables in the caregiver's family as exogenous variables, is proposed to account for caregiver's behavior to elderly parents-in-law. The model is estimated with data collected from a probability sample of housewives in Kwangju, Korea. Estimation of the model, separately for caregiver's fathers-in-law and mothers-in-law, in terms of maximum likelihood(ML) procedures in LISREL8 reveals that housewives' educational attainment, father-in-law's age, father-in-law's health status, and family size have statistically significant causal. effects on care giving behavior to fathers-in-law, and that housewives' educational attainment, mother-in-law's age, family size, and caregiving attitude have significant causal effects on caregiving behavior to mothers-in-law. Comparison of the two estimated models indicates caregiver's educational attainment, caretaker's age, and family size are prominent determinants of caregiving behavior that can be commonly generalized to the two models. Except for these common determinants, however, a nonnegligible amount of differences is identified between the two models. The findings are discussed and interpreted with suggesting some salient theoretical and policy implications.

In presented paper there were studied some properties of Benford's law. The existence of this law in not necessary large sets of numbers is a very interesting example that can show how the complex phenomena can appear in the positional number systems. Such systems seem to be very simple and intuitive and help us proceed with numbers. However, their simplicity in the case of usage in our lifetime is not necessary connected with the simplicity in the case of laws that govern them. Even if this laws indicate the existence of self-similar properties.

In 1926, Alfred Lotka examined the frequency distribution of scientific productivity of chemists and physicists. He observed that the number of persons making n contributions is about $1/ n^2$ of those making one and the proportion of all contributions that make a single contribution is about $60\%$. Investigator studing the applicability of 'Lotka's Law' to Mathematics and to Mechanical engineers have fitted Lotka's Law and concluded that the law applied to these subject fields.

A contract is made when both parties have reached agreement, or they are deemed to have. After contract the law recognizes rights and obligations arising from the agreement. In order to discover whether agreement was reached between these two parties, we have to analyse the process of negotiation. Recently The People's Republic of China legislated a New Contract Law, which has come into effect since 1st of October 1999. This Law adapts the rules of United Nations(Vienna) Convention on Contracts for the International Sale of Goods and the Unidroit Principles for International Commercial Contracts. And this law is now widely enforced to commercial transactions between individuals, enterprises or other economic organizations of the People's Republic of China and foreign enterprises. Therefore, the foreigner who wish to make a sales contract with Chinese should understand the rules of New Contract Law of China. According to this New Law only a contract which contain offer and acceptance is valid and binding, and it is also pointed out that terms of contact must be certain. Though an oral contract is usually equivalent to a written one, in a case of commercial transactions written contract with signature is desirable. The purpose of this paper is to analyze the new rules of this Law and the new features of their application to commercial transactions in China.

The Korean Conflict of Laws Act recently incorporated much of the European Union's recent revision in "EC Convention on the Law Applicable to Contractual Obligations (Rome 1980)"(hereinafter Rome Convention). With the revision of Rome Convention applied to contractual obligations,"Regulation (EC) No 593/2008 of the European Parliament and of the Council of 17 June 2008 on the law applicable to contractual obligations (Rome I)"(hereinafter Rome I) has taken effect on December 2009. Before the effectivation of Rome I, "Regulation (EC) No 864/2007 of the European Parliament and of the Council of 11 July 2007 on the law applicable to non-contractual obligations (Rome II)"(hereinafter Rome II) has come into effect on January 2009. This means the revision of certain rules and its practical implications need an in-depth study on governing law rules under Rome I which provides newly effected governing laws applicable to contractual obligations. Moreover, uniform choice of law rules on non-contractual obligations needs to focus especially on marine insurance contract. Where policy assignment and subrogation causes, how to decide the governing law which will be applied to the insurer as a third party? This article attempts to analyze emerging legal issues in legal regimes determining choice of law, especially those in international marine insurance contracts. This will help Korean practitioners to be dialed in legal affairs under English Law as the governing law in their contracts.
