문자열 간추리기(string ordering)에 관한 국제 표준인 ISO 14651의 내용 중 공통틀표(CTT)의 한글 관련 규정은, 첫 가끝 조합형과 완성형 어느 쪽으로도 부호화가 가능한 한글 문서의 특성을 무시하여 이들을 분리하여 기술함으로써 두 부호값 체계에 대한 상호 연관성과 통일성을 잃고 있다. 또한 ordering에 필수적인 UCS 완성형 글자마디의 무게값(weight)을 할당하지 않음으로써 형식적 완결성과 내용적 명료성을 잃고 있다. 이에 따라 본 논문은 CTT의 규정을 한글 문서의 부호화 방법에 따라 유형별로 검토하여 그 문제점을 지적하고, 이와 관련하여 어떤 한글 문서이든 이를 일관성 있게 ordering할 수 있도록 하는 \"CTT 한글 부분의 개정 방안\"을 제안함으로써 한글 ordering과 관련된 현 CTT 상의 여러 문제점들을 해결하고자 하였다.해결하고자 하였다.

In a Guest-Host cell the orientational ordering of dyes doped into liquid crystals has been investigated. To evaluate the influence of the host liquid crystals on the ordering of the dyes we have measured precisely the ordering parameters of the liquid crystals by using the dichroic ratio of the absorbances for infrared light polarized parallel and perpendicular to the diector. Our experimental results show that the ordering of the dyes can be expressed as a function of not only the molecular structure of the dyes but also the order parameter of the liquid crystals. These functions are dependent on the kinds of the liquid crystals and the dyes. Particularly the combination such as anthraquinone dyes doped into cyanobiphenyl liquid crystals show a very high ordering parameter. This is considered due to a strong intermolecular interaction between the dipoles of both liquid crystals and dyes.

Maintaining a complex repairable system can be achieved by repairing, replacing, or any other activities. This paper proposes a joint optimization policy that is composed with ordering and replacing under minimal repair for the complex system. For this purpose, we derive the expected cost due to the minimal repair, ordering, downtime, inventory costs, and salvage value of units that follow generally distribution. Some properties about the optimum ordering policy that are suggested for our purpose shows that the optimum ordering policy minimizing the expected cost is either one of the two typical policies : (1) the original unit is replaced as soon as the ordered spare is delivered, or (2) the delivered spare is used as inventory part until the original unit fails.

백트래킹을 이용한 깊이우선탐색에서 해를 빨리 찾기 위한 방법 중 하나는 결정변수의 순서를 효과적으로 배열하는 것이다. 이 때 문제의 동적 및 정적 특성을 고려한 변수 순서화 알고리즘 개발은 매우 중요한 문제이다. 그러나 문제에 적합한 최적의 변수 순서화 알고리즘을 개발하는 것은 어려운 문제이다. 본 논문에서는 변수의 속성에 기반을 두어 문제의 형태를 규정하는 문제분류규칙을 제안하고 이 규칙을 이용하여 문제에 적합한 변수 순서화 알고리즘의 형태를 예측할 수 있게 한다. 결정변수가 동적 및 정적 특성을 갖는 DS-type 문제로서 주파수 할당문제를 선택하여 최적의 변수 순서화 알고리즘을 예측한다. 또한 문제분류규칙에 의해 생성되지 않는 특별한 형태의 문제인 기지국 위치문제를 적용하여 제안하는 문제분류규칙의 효용성을 입증한다.

The purpose of this paper is to reveal two problems in the existing inventory systems in retail market, and to suggest a Two-Bin System under Automatic Ordering System considering only base-stock. Large retailers already have a sophisticated inventory system based on an automatic ordering principle. However, why does the out-of-stock (OOS) happen in large discount stores in spite of having a good inventory system? This paper suggests two systems after finding the root causes concerning the previous question. For evaluating the performance of each system, the random 200 data set in each sample group was generated from MINITAB 16 and obeyed the Poisson distribution. The existing inventory system in retail market cannot help generating OOS due to indwelling contradiction in itself. The reasons are the ordering deadline and the relationship between ordering quantity and base stock. This paper also demonstrates that these previous studies on inventory fall into the closed loop. Also the paper shows that the performance of the replenishment policy was better than traditional methods dealing with ordering quantity and base stock.

This study examines the factors influencing the use of mobile food ordering applications and their impact on consumption behavior amidst recent societal changes. It re-evaluates the relevance of factors from the UTAUT2 theory in predicting customers' behavioral intentions. Additionally, the study explores the moderating effect of confidence in food safety measures (CFSM). Quantitative research methods are employed. A structured questionnaire that measures the psychological factors, behavioral intention, and actual usage of mobile food ordering applications was used to collect customer data. Regression and moderation analyses are conducted to test the hypotheses and examine the moderating role of CFSM. The findings reveal that performance expectation, effort expectation, and habit significantly predict customers' intention to use mobile food ordering applications. Moreover, for customers with high CFSM, social influence, facilitating conditions, and hedonic motivation add additional contributions to their behavioral intention. This study extends the UTAUT2 theory by applying it to mobile food ordering applications and examining the influence of CFSM. It identifies the specific factors that drive customers' intention to use these applications and highlights the importance of CFSM as a moderating factor. The findings offer theoretical insights and practical implications for researchers and practitioners in the mobile food ordering industry.

In this paper, we show that NQD ordering is preserved under mixture, limits in distribution, invariant under transformation of increasing functions. Finally, we explore the characterization and limit in distribution of RTD(LTI) ordering and some properties.

In this paper, we consider the c-sample location problem for ordered alternatives using median ranked ordering-set samples(MROSS). We propose the test statistic using the median of samples that have the same ranked order in each cycle of ranted ordering-set sample(ROSS). We obtain the asymptotic property of the proposed test statistic and Pitman efficiency with respect to other test statistic. In simulation study, our proposed test statistic has good powers for some underlying distributions we consider.

In this paper, we introduced a new asymptotic pairwise negatively dependent(APND) structure of stochastic processes. We are also important to know the degree of APND-ness and to compare pairs of stochastic vectors as to their APND-ness. So, we introduced a definitions and some basic properties of APND ordering. Some preservation results of APND ordering are derived. Finally, we shown some examples and applications.
