  • This study focuses on analysing the period of carrier's responsibility. The Hague Rules apply only while the cargo is in carriage. This period of carrier's responsibility begins when the ship' tackle is hooked on the goods for loading and continues until they are unhooked from the lifting gear after discharge. The Hague Rules are consequently said to apply from tackle to tackle. Also The Hamburg Rules lays down the basic principle that the carrier will be responsible for the goods during the time he is in charge of them at the port of loading, during the carriage and at the port of discharge. These period of carrier's responsibility should be determinated according to custom of the port of loading and discharge because of the importance of local custom in the loading and discharge of goods.

  • This study aims to find out the associative relationship between dementia and comorbidities. To conduct this study, we used KNHDIS(Korea National Hospital Discharge In-depth Injury Survey) data from 2009 to 2018 provided by the KDCA(Korean Disease Control and Prevention Agency) annually. We used MySQL for data preprocessing and R for data analysis. As a result of applying the Apriori algorithm criteria of support(≥0.01), confidence(≥ 0.6), and lift(>1), seventeen rules related to dementia were discovered. The diseases associated with dementia were diabetes mellitus, hypertension, disorders of lipoprotein metabolism, glomerular disorders in diabetes mellitus, renal diseases, cardiovascular disease, cerebrovascular disease, and other urinary system disorders. This study can be utilized as primary data for the care of patients with dementia and provides implications for improving effective dementia prevention policies.

  • Quantitative association rules apply a binary association to the data which have the relatively strong quantitative attributions in a large database system. When a domain range of quantitative data which involve the significant meanings for the association is too broad, a domain requires to be divided into a proper interval which satisfies the minimum support for the generation of large interval items. The reliability of formulated rules is enormously influenced by the generation of large interval items. Therefore, this paper proposes a new method to efficiently generate the large interval items. The proposed method does not lose any meaningful intervals compared to other existing methods, provides the accurate large interval items which are close to the minimum support, and minimizes the loss of characteristics of data. In addition, since our method merges data where the frequency of data is high enough, it provides the fast run time compared with other methods for the broad quantitative domain. To verify the superiority of proposed method, the real national census data are used for the performance analysis and a Clunix HPC system is used for the parallel processing.

  • Construction industry is one of the most dangerous industry. As the construction accidents occur due to the repeated factors found in each accidents, there is a limitation in analyzing all types of occupational accidents by the existing descriptive analysis and statistical test. In this study, we classified safety accidents caused by falling objects among the accident types occurring at construction sites into fatal and nonfatal accidents and deduced the factors. In addition, we deduced the association rules among the safety accidents factors caused by falling objects through the association rule analysis method among the machine learning techniques. Therefore, considering the association rules for fatal and nonfatal accidents proposed in this study, it would be possible to prevent accidents by searching for countermeasures against safety accidents caused by falling objects.

  • This study has the purpose to investigate other countries' arbitrator systems to compare with the current KCAB's system and to find their merits and demerits so that we can make up for the demerits of KCAB's arbitrator system and to make the most use of its merits. The most important factor of arbitral procedure is the arbitrator. If we compare clauses related with the arbitrator to KCAB's arbitration rules, expand the merits of it and apply the merits of other arbitrating organs, KCAB's arbitration can avoid criticism which it has got so far while it was handling the international cases. Also, we may need to grow up the role of the executive office in the range of respecting the self-government of the concerned party for the rapid proceeding of arbitral procedure. According to the foreign countries' international arbitration rules, they go with the process that they firstly give the concurrence period to the concerned parties, especially related with the arbitral procedure such as selection of arbitrator or filling the vacancy of the arbitrator, and as for the concerned party who doesn't fulfill within that period, the arbitrating organ or the other one corresponding to the pertinent arbitrating organ in case of the ad-hoc arbitration rules fulfill instead.

  • In the case of multiple commerce contracts in commerce, as well as multiple contracts related to it, a solution for the merging of arbitration proceedings is necessary in order to ensure uniformity of dispute resolution. Since the arbitration proceedings are based on the parties' agreement, no merging of two or more arbitration proceedings may transpire unless all parties agree. Claims of merging in arbitration proceedings lead to problems such as lack of party autonomy, resulting from lack of consent of the parties to merging, and how to appoint an arbitrator in a multilateral arbitration proceeding. Many of the major arbitration bodies have recognized the significant benefits of the terms of consolidation, and have recently revised the Arbitration Rules to include or extend existing clauses to reflect the needs of the parties. This study introduces the merging provisions of several selected major arbitration rules, such as the ICC, Switzerland, SCC, LCIA, SIAC, HKIAC, ACICA, and UNCITRAL rules, and looks at the main similarities and differences among the rules.

  • This paper presents a methodology of developing reservoir operating rules which can consider the reliability levels incorporated with the discharge policy. The operating rules were derived based on the regression and risk analysis of the optimally operated results by using the long term historical and generated reservoir inflows. The methodology was applied to the operation of the Chungju reservoir system which is consisted of two reservoirs and powerplants, and monthly operation rules were developed. Simulations were performed by using the developed operating rules can not only significantly improve the output from the existing system but also improve the reliability incorporated with the output.

  • Since he was a leading figure in nineteenth century architecture, Viollet-le-Duc's architectural theory is crucial to the foundation of modern architecture. He has been called a Gothic Revivalist, a Structural Rationalist and a Positivist. The first title was perhaps due to his vigorous restoration of Gothic works such as $N\hat{o}tre$ Dame, but he did not adore the Gothic style just for itself. Rather, he hoped to deduce some principles from the style. So how did he manage this? In his book "Entretiens sur l'Architecture (Lectures on Architecture), published between 1864 and 1872, he mentions using Descartes' four rules for reaching architectural certainty in contrast with the chaotic situation during that modernising period. Furthermore Viollet-le-Duc's theory can be seen as a serious attempt to translates Descartes' philosophical rules into systems of architectural speculation. Descartes' four rules of doubt are anchored in mathematical propositions, and without mathematical distinctions, none of these rules are valid. In other word, mathematics for Viollet is the yardstick of judgement between distinctness and indistinctness. Many architectural problems arise from this view. In this paper, the validities of applying Descartes' method of doubt to architectural discourse will be discussed in order to address the question:-Did Viollet-le-Duc clearly grasp Cartesian method by which memory was erased from the world?

  • This research examined children's perception of parental authority within three different types of rules : moral, social-conventional, and personal issue. Specifically, two major aspects of parental authority-legitimacy and obedience-were explored. The subjects of this study were 120 children from an elementary school in Kwangju. There were 40 subjects (20 males and 20 females) in each of three age groups: 7-, 9-, and 11- year-olds. The subjects were administered an interview individually. Based on Tisak (1986) open-ended questions concerning three family rules (moral rule, social-conventional rule, personal issue) were administered. Responses to the assessment questions were coded as positive or negative. Responses to the judgment conception questions were coded into 7 categories : Other's Walfare, Social Coordination, Personal choice, Deservedness of Punishment for Wrongdoing, Existence of Authority, Conflicting Personal Interest and Authority, and Personal Development. Statistical analysis of obtained data was by percentage and ${\chi}_2$ test using log linear procedure. The results were as follows : (1) There was a significant main effect of type of rule on the children's assessment regarding legitimacy and obedience of parental authority. The children (average 96%) stated that it was all right for parents to make rules prohiliting an act when it pertained to moral and social conventions. However, the majority of the children (average 40%) stated that it was not right for parents to regulate personal issues. (2) There was a significant interaction effect between type of rule and age. (3) There was a significant main effect of rules on the children's judgment conception of parental authority. (4) There was a significant interaction effect between rules and ages on children's judgment conception of parental authority.
