오늘날 우리는 HTML 폼을 통해 지역 데이타베이스뿐 아니라 원격 데이타베이스도 쉽게 접근할 수 있다. HTML 폼으로 데이타베이스 웅용을 구현하는 것이 쉽기는 하나 아직 HTML 폼과 CGI 프로그램은 코딩되어야만 한다. 본 논문에서는 웹 기반 데이타베이스 웅용을 자동 생성하는 도구를 소개하는데, 이 도구는 응용 데이타베이스 구축을 위한 SQL 문장들, 사용자 인터페이스로 사용되는 품들, 그리고 그 폼들을 통해 이루어진 질의를 처리하는 자바 서블릿을 생성한다. 생성될 테이블들과 폼들은 응용을 위한 클래스 다이어 그램으로부터 결정된다. 따라서 WebSiteGen으로 명명한 우리의 소프트웨어 도구는 웹기반 데이타베이스 응용의 구현을 자동화한다.

Our final purpose may be to introduce generalized differential forms on the space Map(S, M) of mappings from a manifold S into a manifold M and discuss the differential geometry of the space Map(S, M) from the point of the generalized forms. Here we take a subspace X of the space Map(S,M) and we introduce the generalized differential forms on X, taking the dual to the chain space with the flat norm. This method of construction allows us to discuss a sufficient condition for a subspace Y of X to admit the generalized differential forms and the natural integration as the dual operation.

This study investigates the behavioral characteristics and forms of phosphorus in the sediment according to the oxygen condition (aerobic/anaerobic). In the behavioral characteristics analysis, Al-P and Fe-P concentrations were the highest among the forms of inorganic phosphorus, and therefore had the strongest impact on sorption and release corresponding to environmental condition changes. In the experimental investigation of the inorganic forms of phosphorus in the sediment according to the oxygen condition, we determined that the forms of inorganic phosphorus did not greatly affect the sorption or release reaction because the distribution ratios of the inorganic forms remained constant corresponding to changes of dissolved oxygen (DO) conditions. In contrast, the forms of organic phosphorus in the sediments affected both sorption and release. Furthermore, labile-P and moderately labile-P forms were the major mechanisms of sorption in sediment. Moderately labile-P was the greatest contributor to phosphorus release action in sediment. As environmental changes are important for the behavioral characteristics of phosphorus in sediment, the forms of phosphorus should be considered to have a greater effect, especially in the organic phosphorus case. Therefore, based on the present study results, sediment evaluation aimed at controlling internal pollutants in reservoirs should include an examination of the forms of phosphorus present, as well as the release characteristics of environmental changes, which are influential factors of phosphorus control. Further research in this field is required.

Purpose - The study investigates the impact of consignment on the economic performance in the supply chain with three stages. Through the analysis on distinct forms of consignment application, this study intends to answer to the question of how the consignment should be used in the multi-stage supply chain. Research design, data, and methodology - The proposed mathematical model represents the supply chain system with a manufacturer, a wholesaler, and a retailer. Three different forms of consignment application are considered depending on which stages adapt the consignment, and their system profits are compared with the traditional non-consignment system in numerical examples. Results - The numerical examples show that the serial consignment application performs better than any other forms of consignment as well as the non-consignment system. The additional analysis indicates that the system profit is significantly sensitive to the consignment rate. Conclusions - The outcome of this study implies the potential of consignment to improve the system performance even in the multi-stage supply chain system. Meanwhile, each supply chain member's preference to the specific form of consignment application could be different depending on which stage he has. All the supply chain members should jointly determine the appropriate consignment rates to obtain the best system performance.

PURPOSE. The aim of this study was to determine whether two methods of documentation, print and electronic forms, for the assessment of patient-reported outcomes (PRO) in complete denture wearers provide comparable results. The study also quantified the time needed for filling the forms by each method. MATERIALS AND METHODS. Thirty participants enrolled in a university clinic answered two forms (a questionnaire for denture satisfaction and OHIP-EDENT). They provided answers with two application methods in a random order, with a one-month interval between them: (1) electronic forms on a tablet computer; and (2) print forms. The methods were compared in terms of mean results, correlation/agreement, internal consistency, and spent time. RESULTS. Mean results for both methods were similar for each denture satisfaction item (100-mm VAS) and OHIP-EDENT summary score. Both questionnaires presented good internal consistency regardless of the application method (Cronbach's ${\alpha}=0.86$ or higher). Correlation and agreement between the methods regarding specific items was at least moderate for the majority of cases. Mean time for the electronic and print forms were 9.2 and 8.5 minutes, respectively (paired t test, P=.06, non-significant). CONCLUSION. The electronic method is comparable to print forms for the assessment of important PRO of prosthetic treatment for edentulism, considering the results and time needed. Findings suggest the viability of replacing print forms with a tablet for applying the tested inventories in clinical trials.

컴퓨터 기술의 발전에 따라 많은 디지털디자인도구가 개발되어 활용되면서 디지털 프로세스에 의한 구체적인 방법론의 연구가 증가하고 다양한 비정형 형태가 나타나고 있지만, 건축 형태 생성에 있어 접근성과 다양한 환경을 추구하는 모바일기술의 적용과 실용화에는 한계를 보여주고 있다. 이에 본 연구에서는 선행연구와 모바일활용 현황을 분석하여 연구의 필요성을 인지하고, 모바일환경에서 비정형 형태 생성 가능성을 제시 하고자 한다. 즉, 비정형 건축의 아이디어구현과 학습을 위한 스마트 모바일 애플리케이션의 필요성을 인지하고 디자인 프로세스 중 건축초기단계에서 비정형 형태생성을 가능하게 하는 스마트모바일 애플리케이션 기술의 기본을 설정 하는 것이다. 이를 위해 본 연구에서는 프로세스에 의한 분석적 적용이 아닌 선택적 적용의 방법을 제시하여 모바일적용의 가능성을 제시하고자 한다.

In this note, we study arithmetic properties for the exponents of modular forms on ${\Gamma}_0(p)$ for primes p. Our aim is to refine the result of [4] by using the geometric property of the modular curve of ${\Gamma}_0(p)$.

Moments of skew t random vectors and their quadratic forms are derived. It is shown that the moments of the sample autocovariance function and of the sample variogram estimator do not depend on a skewness parameter.

We find congruences for the t-expansion coefficients of a Drinfeld modular form for ${\Gamma}^+_0$(Q), where Q is a monic irreducible polynomial. As an application we obtain new congruence relations for the t-expansion coefficients of Drinfeld modular forms for ${GL_2}(\mathbb{F}_q[T])$.
