It is very important for a teacher to know what his students know and what they do not; however, it seems not true for the most Korean secondary school science techers. This study tried to find students' misconception Newton's third law and the sources of the misconceptions. The researcher examined 609 students from middle schools, high schools, and college. In this study, students' understanding on Newton's third law were examined by school level, sex, stream (science and liberal arts), and departments. The following results were obtained by this study. 1. Students' understanding seemed to be improved continuously from middle school to university; however, their misconception (the most frequent incorrect selection of options of the test items) did not changed very much. 2. Students' answers were significantly affected by size of objects, existence of physical contact and the existence of life in the objects. 3. The answer were significantly affected by the source of attraction. 4. The answer to Newton's third law were affected by the magnitude of potential force which the target bodies have, state of motion, velocity, weight, friction and acceleration. This study could show the sources of the misconception on Newton's third law. The identified sources could be very useful for designing an instruction to teach Newton's third law in schools and universities.

Ecological monitoring provides indispensable data for biodiversity conservation and sustainable resource management. However, the complexity and variability inherent in ecological monitoring data necessitate robust verification processes to ensure data integrity. This study employed Benford's Law, a statistical principle traditionally used in fields such as finance and health sciences, to evaluate the authenticity of ecological monitoring data related to the abundance of migratory bird species across various locations in South Korea. Benford's Law anticipates a specific logarithmic distribution of leading digits in naturally occurring numerical datasets. Our investigation involved two stages of analysis: a first-order analysis considering the leading digit and a second-order analysis examining the first two digits of bird population counts. While the first-order analysis displayed moderate conformity to Benford's Law that suggested overall data integrity, the second-order analysis revealed more pronounced deviations, indicating potential inconsistencies or inaccuracies in certain subsets of the data. Although our data did not perfectly align with Benford's Law, these deviations underscore the complex nature of ecological research, which is influenced by a multitude of environmental, methodological, and human factors.

The agreement to arbitrate is a central feature of commercial arbitration and the lack of a valid arbitration agreement is recognised as a reason why any arbitral award may not be recognized as binding by the courts or may be set aside. The purpose of this paper is to clarify the China's present arbitration law and practice in respect of determination of the validity of international commercial arbitration agreement. Most arbitration laws only require an arbitration agreement to be "in writing". But the arbitration law of the China require an arbitration agreement shall contain the following: 1. The expression of application for arbitration. 2. Matters for arbitration. 3. The arbitration commission chosen. And China's present arbitration law and practice in respect of determination of the validity of international commercial arbitration agreement are somewhat different from the other nations.

Having gone through socioeconomic changes from an agricultural to a post-industrial society, mental health system accordingly has been changed. In Korea where the socioeconomic change has been so rapid, the mental health system and law have been behind the socioeconomic system. Post-industrial society needs more humanized and advanced mental health system, however, Korean mental health law reflects ideology of Korean society in industrial age. This paper attempts to assess the significance Korea's Mental Health Law against the backdrop of socioeconomic changes. A substantial part of the report is devoted to identifying discrepancies between Korea's Mental Health Law and the perspectives of post-industrial ideology and areas for improvement. Improvement in mental health law should take place in line with the changes occurring in socioeconomic environments, the social concept of family, and the public awareness of human rights. Korea's mental health law should be changed in a way to improve hospitalization procedure for people with mental illness, promote the opening of mental health facilities and improve the quality of the lives of the mentally ill. Further changes are deemed necessary in the public and media view of mental illness. Also, the national budget will have to be increased with a view to raise the social rights of those with mental illness to receive quality rehabilitation services.

Civil lawsuits have been the main instruments to resolve any civil disputes until recent times but it has its limitations in resolving all disputes in the specialized and technical disputes only according to the civil trial process. Therefore, many countries have carried out a series of discussions and investigations into the system of Alternate Dispute Resolution(ADR). It should especially be noted that all related countries in the world have enacted a basic ADR law to accelerate the usage of the ADR system. The most representative cases are the American Alternative Dispute Resolution Act of 1998 and Japan's Alternative Dispute Resolution Promotion Law set up in December 2004. As such, there is a need for Korea to enact a basic law regarding ADR following the world trend of major nations. This paper looks closely not only into the enactment circumstances and contents of Japan's ADR law whose legal system is similar to that of Korea but also the aftermath discussions of the Japanese academic circles into consideration, in the hopes of providing reference data for the legislation of the Korean ADR system and further aiding in the development of the ADR law theory.

From the field survey of the main ethnic minority areas in the south China, it is found that political, economic, cultural and natural environmental changes are the main reasons leading to the change of customary law. The power mechanism of the customary law change include the three aspects, such as the promotion of country elite, the dominance of grassroots government, and the daily demands of the villagers, which promote the change of customary law alone or together. Through the application of customary law, the country elites can adjust and refine the rules of customary law in order to make out the new customary law and promote its development. In the current pattern of rural governance, grassroots self-government is actually the "official supervision of people's autonomy". The executive power of the grassroots government often intervene the practice of customary law and other informal rules. This is another mechanism of customary law change. Customary law arises from the practice of the daily life of the villagers. If the villagers think that the norms of customary law cannot meet the actual needs of daily life practice, the customary law will be promoted in the form of collective consultation. This is the most important dynamic practice mechanism of customary law change. Transformation and abandonment are the two ways to change customary law. No matter what kind of change does not lead to the demise of the customary law system, the demise of the customary law is only an outdated result, which is made by the universality, nature and objectivity of customary law. The procedure of customary law change is the process of continuation and rebirth about customary law. The result of the change is to produce the new customary law of keeping pace with the times, and the customary law will be presented with new content and form after the change. The continuation of customary law means the inheritance of traditional customary law, but it is based on the transformation of traditional customary law. The rebirth of customary law means that the traditional customary law is completely discarded. But it will produce new customary law rules and be based on the needs of social life practice. Customary law occupies a pivotal position in the normative system and the national law cannot be replaced. The purpose of customary law change will let the customary rules better adapt to the development of modern society, adjust the social relations more reasonably and better meet people's needs of production and life, which is decided by the character of customary law.

For arbitrary random variables {$X_{n},n{\geq}1$}, the order of growth of the series. $S_{n}\;=\;{\sum}_{j=1}^n\;X_{j}$ is studied in this paper. More specifically, when the series S_{n}$ diverges almost surely, the strong law of large numbers $S_{n}/g_{n}^{-1}$($A_{n}{\psi}(A_{n}))\;{\rightarrow}\;0$ a.s. is constructed by extending the results of Petrov (1973). On the other hand, if the series $S_{n}$ converges almost surely to a random variable S, then the tail series $T_{n}\;=\;S\;-\;S_{n-1}\;=\;{\sum}_{j=n}^{\infty}\;X_{j}$ is a well-defined sequence of random variables and converges to 0 almost surely. For the almost surely convergent series $S_{n}$, a tail series strong law of large numbers $T_{n}/g_{n}^{-1}(B_{n}{\psi}^{\ast}(B_{n}^{-1}))\;{\rightarrow}\;0$ a.s., which generalizes the result of Klesov (1984), is also established by investigating the duality between the limiting behavior of partial sums and that of tail series. In particular, an example is provided showing that the current work can prevail despite the fact that previous tail series strong law of large numbers does not work.

The stdy of this study is to explore whether there is a social class difference in the relationship of mother and daughter-in-laws. The findings and summarized as follows. in the upper class the relationship of mother and daughter-in-laws seems 'fictitious one' In the middle class when her husband's occupation status is higher than his father's the relationship of mother and daughter-in-laws seems 'the relationship which is trobultesome only on daughter-in-law's behalf. When her husbands' occupation status is similar to his father's and her family is living together with in-laws and she and her mother-in=law are housewives the relationship of mother and daughter-in-laws seems 'the troublesome relationship for the both parts of mother and daughter-in-laws' In the same situation as above except the fact that the mother-in-law is housewife and daughter-in-law working the relationship between mother and daugther-in-laws seems apper to be 'interdependence' When her husband is self- mployed the daughter-in-laws keeps the interdepen-dent relationship with the mother-in-law. In the low class the relationship of mother and daughter-in-laws seems 'neglect' or 'conflicting'.

The culpa in contrahendo is a doctrine that "damages should be recoverable against the party whose blameworthy conduct during negotiations for a contract brought about its invalidity or prevented its perfection". In China, Chinese Civil law gradually adopted Culpa in Contrahendo under the former 'economic contract law' and the 'general rules of the civil law', then the legal system of culpa in contrahendo was formally established under Contract Law of the People's Republic of China(CLPRC) in 1999. To put it concretely, Art. 42, 43, 58 of the Chinese Civil Law expressly establishes a culpa in contrahendo liability derived from a principle of good faith governing pre-contractual negotiations. however, in general, culpa in contrahendo has been recognized a independent legal liability as distinct from contractual default liability and torts liability. This article provides a general description of the characteristics of culpa in contrahendo under Chinese Contract Law, and both theoretical issues that have arisen in Chinese academics and relevant important precedent in Chinese Courts. This article also analyzed trend of judgment on precedents that the Supreme Peoples's Court of the PRC applied culpa in contrahendo.

The graph of the parallelogram law is well known, which gives rise to the characterization of an inner product space among normed linear spaces [6]. In this paper we will sketch graphs of its deformations according to our previous paper [7, Theorem 3.1 and 3.2]; each one of which characterizes an inner product space among normed linear spaces. Consequently, the graphs of some classical characterizations of an inner product space follow easily.
