다중 값이란 속성 값이 집합인 것을 말한다. 즉, 관계형 데이터베이스에서 자료 유형이 집합인 속성을 의미한다. 이러한 다중 값 속성 처리는 기존 데이터마이닝 기술 자체로는 처리한 수 없으며 후처리나 선처리 과정을 이용하여 처리하고 있다. 전처리나 후처리 과정을 통해 처리할 경우 수행과장에 있어 많은 시간이 소요되고 혹은 타당하지 않은 규칙이 생성되는 문제점을 가지고 있다. 특히 연관화 기법 특성상 분석하고자 할 항목이 증가할수록 연관성의 수가 지수(exponential)단위이기 때문에 이를 해결하는데는 상당한 어려움이 따르게 된다. 본 논문에서는 관계형 데이터베이스 테이블 구조에서 데이터 마이닝의 수행을 위한 전처리나 후처리의 과정을 고려하지 않음으로 위에서 언급된 문제점들을 해결하고자 한다. 특히 데이터 변환 작업 없이 정량적(Quantitative)연관 규칙과 연관 규칙(Market Basket Analysis)의 혼합 형태의 규칙을 생성할 수 있게끔 알고리즘을 확장하여 보다 효율적인 규칙이 생성될 수 있도록 한다. 마지막으로 Each Movie 데이터를 사용하여 확장한 알고리즘의 다중 값 속성 처리 방법의 효율성과 타탕성을 검증한다.

연관규칙은 데이터 안에 존재하는 항목들간의 종속 관계를 찾아내는 것이다. 기존의 연구에서는 연관규칙 탐사 과정에서 발견항목 자체에만 관심을 두고 연구되어 왔다. 즉, 연관규칙 생성을 위한 후보 항목은 수량을 배제한 항목 대 수량비가 1:1인 상태에서 규칙을 발견하는 연구였다. 이것은 항목의 구매 수량에 관계없이 같은 가중치로 규칙을 발견하는 문제점을 갖고 있다. 두 번째 문제점은 연관규칙은 시간적 연장선상에서 발견되는 규칙이라 할 수 있다. 즉, 규칙을 발견하는 과정에서 모든 자료를 동일한 시간적 가중치를 두어 취급하는 것이다. 본 논문에서는 각각의 아이템을 (아이템, 수량)의 묶음 단위로 후보항목을 만들어 수량적 속성이 포함된 아이템 대 수량 비 1:n의 관계에서 규칙을 발견하는 방법을 제안한다. 또한 과거의 자료들을 이용하여 예측할 때 모든 자료를 동일하게 취급하기보다는 최근의 자료에 더 큰 비중을 주는 예측법을 사용하여 연관규칙 발견의 신뢰성을 높인다. 성능평가는 기존의 알고리즘과 비교하여 제안한 알고리즘의 성능향상 및 타당성을 보인다.

최근 대용량의 데이터베이스로부터 연관규칙을 발견하여 이를 활용하는 단계에서 이러한 연관규칙을 수량항목에도 적용할 수 있도록 확장하는 연구가 소개되고 있다. 본 논문에서는 수량 항목을 이진항목으로 변환하기 위하여 빈발구간 항목집합(Large Interval Itemsets)을 생성할 때 수량 항목이 특정 영역에 집중하여 발생하거나 골고루 분포되어 있지 않은 경우, 이러한 지역성(locality)을 고려하여 빈발구간 항목집합을 생성하는 방법을 제안한다. 이 방법은 기존의 방법보다 많은 수의 세밀한 빈발구간 항목들을 생성할 수 있을 뿐만 아니라 의미 있는 구간을 중심으로 빈발구간 항목들이 순서대로 생성되기 때문에 세밀도를 판단하여 활용할 수 있으며, 원 데이터가 가지고 있는 특성의 손실을 최소화할 수 있는 특징이 있다 또한 인구센서스등 실 데이터를 사용한 성능평가를 통하여 기존의 방법보다 우수함을 보였다.

Water supply is continuously suffering from frequent droughts under climate change, and such extreme events are expected to become more frequent due to climate change. In this study, the decision scaling method was introduced to evaluate the drought vulnerability under future climate change in a wider range. As a result, the water supply reliability of the Boryeong Dam ranged from 95.80% to 98.13% to the condition of the aqueduct which was constructed at the Boryeong Dam. Furthermore, the Boryeong Dam was discovered to be vulnerable under climate change scenarios. Hence, genetic algorithm-based hedging rules were developed to evaluate the reduction effect of drought vulnerability. Moreover, three demand scenarios (high, standard, and low demand) were also considered to reflect the future socio-economic change in the Boryeong Dam. By analyzing quantitative reliability and the probability of extreme drought occurrence under 5% of the water storage rate, all hedging rules demonstrated that they were superior in preparing for extreme drought under low-demand scenarios.

Geospatial input setting to represent the reality of spatial distribution or quantitative property within model has become a major interest in earth system simulation. Many studies showed the variation of grid resolution could lead to drastic changes of spatial model results because of insufficient surface property estimations. Hence, in this paper, the authors proposed Monte Carlo Integration (MCI) to apply spatial probability (SP) in a spatial-sampling framework using a three-dimensional point cloud (3DPC) to keep the optimized spatial distribution and area/volume property of buildings in urban area. Three different decision rule based building identification results were compared : SP threshold, cell size, and 3DPC density. Results shows the identified building area property tend to increase according to the spatial sampling grid area enlargement. Hence, areal building property manipulation in the sampling frameworks by using decision rules is strongly recommended to increase reliability of geospatial modeling and analysis results. Proposed method will support the modeling needs to keep quantitative building properties in both finer and coarser grids.

The purpose of this paper is to examine the effect of tax planning on firm value of the non-financial firms listed in Vietnam, moderated by the state ownership. In this paper, effective tax rate is used to measure the tax planning; the state ownership is measured by the percentage of state equity holdings, and the firm value is measured by Tobin's Q. The data research is collected from audited financial statements and other statistical documents of 513 firms in the period of 2015-2019, provided by The FiinGroup (Vietnam). According to that, this paper uses quantitative research methods for the panel data. Regression analysis with GLS shows that the tax planning has a negative effect on firm value. In more detail, the association is not a variable in its direction when state ownership takes the role of a moderator. That means, in the perspective of principal-principal conflict, government should improve institutional environment to prevent firms form breaking the rules, especially accounting standards and principles. Assets allocation in tangible assets or making use of large size advantage should be taken into account. In the long run, firms should concentrate on the deployment of resources and the experience of knowledgeable practitioners to produce effective results.

Objectives : Oryeong-san was composed of Alismatis Rhizoma, Atractylodis Rhizoma Alba, Poria Sclerotium, Polyporus, Cinnamomi Cortex, and known to have hundreds of chemical compounds. The aim of this study was to screen chemical compounds constituting Oryeong-san with the drug-likeness and oral bioavailability from the analysis of their physicochemical properties. Methods : A list of chemical compounds of Oryeong-san was obtained from TM-MC(database of medicinal materials and chemical compounds in Northeast Asian traditional medicine). To remove redundant compounds, the SMILES (Simplified Molecular Input Line Entry System) strings of each compound were identified. All of the physicochemical properties for the compounds were calculated using the DruLiTo(Drug Likeness Tool). Drug-likeness was estimated by QED(Quantitative Estimate of Druglikeness) and OB(Oral bioavailability) was checked based on the Veber's rules. Results : A total of 475 compounds were obtained by eliminating duplication among 544 compounds of 5 medicinal materials. Analysis of the physicochemical properties revealed that the most common values were MW(molecular weight) 200~300 g/mol, ALOGP(octanol-water partition coefficient) 1~2, HBA(number of hydrogen bond acceptors) 0~1, HBD(number of hydrogen bond donors) 0, PSA(polar surface area) 0~50 angstrom, ROTB(number of rotatable bonds) 1, AROM(number of aromatic rings) 0, and ALERT(number of structural alerts) 1. QED had 93% of the values between 0.2 and 0.7, and OB had 90% of the value of TRUE. Conclusions : We in this paper screened the candidate active compounds of Oryeong-san using the QED and Veber's rules. In the future, we will use the screening results to analyze the mechanism of Oryeong-san based on systems pharmacology.

The map where so-called 'New Religion' of Korea in the Colonial Era is entangled with 'Religion (Christianity, Buddhism, Shindo)' recognized by the Japanese Government General of Korea and nationalism. Accordingly positive research on how religious ideal and ideology in 'New Religion' in Korea was practically applied and practiced in the society is a crucial task. Meanwhile there is survey data representing the status in the long term from 1860s to early 1930s in regard to 'New Religion' of Korea in the Colonial Era. In other words it is 'Pseudo Religion in Joseon' by Murayama Jijun published in 1935. Most part of them are shown through statistics data. In particular he took a look at the distribution of 'Pseudo Religion', ups and downs of religious influence, faith consciousness, its impact and religious ideological movement and social movement. Therefore, if this statistical data could be utilized through quellenkritik, it is thought to have value of significant reference in research on Korea's 'New Religion'. This paper utilizes many statistics included in the survey data among critical review on recognition in Murayama's 'New Religion in Korea' as basic texts. During the procedure this paper seeks to look at the geology of Korean 'New Religion' and attempts basic consideration in the quantitative term related to trend and ups and downs of the groups. Through this basic research I hope that 'public concern of New Religion' in modern Korea and research on re-establishment will move forward.

In this study, we inquire what is the rules which is implicitly used by the adolescent group about bullying phenomenon. We inquire how to interpret the phenomenon from the adolescents'viewpoint and their opinions of how appearance and clothing determine the extent of bullying. After we discuss this problem, we propose an indirect solution to the cause of bullying. We selected a middle school boy by reason that boys have been more experienced than others according to a previous study and are at a keen adolescent stage of development. Moreover, 'ichime'phenomenon is seriously reported at a middle school student stage in the case of Japan. The purpose of the study was to analyze the following : 1. Research on an actual case of bullying in a middle school student. 2. the adolescents'viewpoint on characteristics of school bullying. 3. The cause of violence and injury from school bullying. 4. How appearance and clothing affect bullying. 5. The preference and uses of clothing worn by adolescents. The process of this study brought a substantially between quantitative and qualitative research. Theses questionnaires were administered to 320 middle school students in Seoul from the 14/sup th/ to the 25/sup th/ of June. The data totaled up to 280 subjects, which consist 121 male students and 159 female students except for invalid data.
