An improved and flexible matrix algorithm for solving interlinked separation problems which is based on the homotopy continuation method has been developed. A flexible model of the interlinked stream in standardized matrix form and JACOBIAN generation I algorithm for homotopy continuation are suggested. Also DOF analysis is performed for easy-understanding of equation based simulation of complex column systems. The Algorithm is tested on several problems of interlinked separation processes and some of results are documented.

The purpose of this study is to establish the relationship between wedding companies and wedding planners and understand the influence of relationship factors on the relationship performance and relationship continuation intention of wedding companies. We conducted an online survey from June to July 2017, and collected 201 responses which were used during analysis. Statistical analysis, including technical statistical analysis, factor analysis, reliability analysis, and regression analysis, was undertaken using SPSS 23. This study shows that among the relationship factors affecting the wedding planner and the wedding company, the computational tie-up has a significant impact on both the financial and non-financial performance of the wedding company, while emotional tie-ups have a significant impact on the non-financial performance of the wedding company, but not on financial performance. As for the effects of relationship commitment to wedding planners on wedding shops' relationship continuation intention, each factor for relationship commitment significantly affected wedding shops' relationship continuation intention. Regarding the effects of wedding shops' relational performance on relationship continuation intention, each factor of performance significantly affected relationship continuation intention. Therefore, wedding companies should make continuous efforts to maintain this relationship and recognize the need for robust relationships with wedding planners as a sure and important competitive tool for attracting customer and generating revenue.

This paper presents a new continuation-based quasi-steady-state(CQSS) time-domain simulation algorithm incorporating a multiplicative aggregated load model for power systems. The authors' previous paper introduced a CQSS algorithm, which has the robust convergent characteristic near the singularity point due to the application of a continuation method. The previous CQSS algorithm implemented the load restoration in power systems using the exponent-based load recovery model that is derived from the additive dynamic load model. However, the reformulated exponent-based model causes the inappropriate variation of short-term load characteristics when switching actions occur, during time-domain simulation. This paper depicts how to incorporate a multiplicative load restoration model, which does not have the problem of deforming short-term load characteristics, into the time simulation algorithm, and shows an illustrative example with a 39-bus test system.

Continuation power flow is a tool that can trace the path of the solution from the base stable solution. However, the base stable solution cannot be calculated when the initial system load is too large to operate at a stable operating point. This case is called as unsolvable case. This paper presents implementation of the optimal load shedding algorithm on continuation power flow. It performs steady-state analysis of power systems at unsolvable case that can occur in contingency analysis. Numerical simulation on 20-bus test system demonstrates that the continuation power flow applying the optimal load shedding algorithm is robust at solvable and unsolvable cases.

연구 목적은 경호학과 학생들의 물리보안 관련 교육서비스품질이 대학생활만족과 학업지속결정에 어느 정도영향을 미치고 있는지 검증하는데 있다. 이를 위해 대학에서 물리보안 교육을 받고 있는 200여 대학생들을 대상으로 2023년 4월 10부터 28일까지 설문조사를 실시하였다. 설문내용에서 변수를 "첫째 교육서비스품질, 둘째 대학생활만족, 셋째 학업지속결정"로 나누어 구성하였으며 이를 토대로 3개의 연구가설을 선정하였다. 분석결과, 연구모형을 살펴보기 위해 회귀분석을 산출하고 그 결과 3개의 연구가설 중에서 "교육서비스품질 ⇨ 대학생활만족, 대학생활만족 ⇨ 학업지속결정"은 통계적으로 유의하게 산출되어 채택되었으나, "교육서비스품질 ⇨ 학업지속결정"은 유의하지 않는 것으로 나타나 기각되었다. 학생들을 대상으로 실시한 설문조사 결과 학생들이 학업지속의향을 높이기 위해서는 대학생활만족이 우선되어야 한다.

This paper presents the continuation power flow system that is under development. The continuation power flow system provides robust solutions of power flow equations at any operating point. The robust convergency enables one to find solutions even at the point where power flow jacobian becomes singular. Basic concept of an algorithm and its application to static voltage stability analysis are presented.

This paper shows how to use continuation-ratio logits for the analysis of structured polytomous data. Here, response categories are considered to have a nested binary structure. Thus, conditionally nested binary random variables can be defined in each step. Two types of factors are considered as independent variables affecting response probabilities. For the purpose of analyzing categorical data with binary nested strutures a continuation-ratio mixed model is suggested. Estimation procedure for the unknown parameters in a suggested model is also discussed in detail by an example.

이 논문의 목적은 ML 프로그램의 소스(source)를 수정하여 ML의 예외상황 처리기의 수행속도를 개선하고자 하는 것이다. ML은 함수를 값으로 주고받을 수 있으며 타입을 이용하여 프로그램을 검사해 주는 언어이다. 이러한 ML의 예외상황 처리부분을 사용함으로서 프로그래머는 쉽게 자신의 프로그램의 예외적인 동작을 기술할 수 있다. 하지만, 이러한 예외상황을 처리하기 위해서는 많은 계산이 필요하기 때문에, 예외상황을 처리하는 프로그램 부분이 병목 현상을 일으키는 경우가 많다. 프로그램의 소스를 바꾸어서 예외상황 처리부분이 존재하지 않는 같은 동작을 하는 다른 프로그램으로 바꾸는 방법은 이미 알려져 있지만, 도리어 수행시간이 느려진다. 위의 바꾸는 방법은 '나중에 할 일을 넘겨주는 방식(Continuation Passing Style)'이라고 부르는 방식으로 프로그램의 소스를 바꾸는 방법을 조금 수정하여, 예외상황을 처리하는 부분을 위의 '나중에 할 일(continuation)'과 같은 방식으로 넘겨주어 예외상황 처리부분이 모두 사라지게 된다. 그러나, 이러한 방식은 모든 프로그램내 표현(expression)을 모두 위와 같은 방식으로 바꾸기 때문에, 이로 인해 발생하는 계산이 예외상황을 처리하는 계산보다 더 많아지게 된다. 이 논문에서는 이러한 단점을 개선하여 프로그램내에서 예외상황 처리부분을 없애는데 꼭 필요한 표현 만을 정적분석을 사용하여 골라내어 이를 선택적으로 변환하는 방법을 사용한다.

Purpose: Aromatase inhibitors (AIs) are widely prescribed for postmenopausal women with breast cancer and are known to cause musculoskeletal pain. This study aimed to identify factors associated with AI continuation intention among breast cancer survivors (BCS). Methods: A cross-sectional survey was conducted on 123 BCS (stages I-III), who had been taking AIs for at least 6 weeks. Participants were recruited from a cancer center in Goyang, Korea, from September to November 2019. Descriptive statistics, Welch analysis of variance, Pearson correlation coefficients, and simple linear regression were used for the analysis. Results: Beliefs about endocrine therapy was a significant predictor of AI continuation intention (β=.66, p<.001). The majority of participants (87.0%) reported experiencing musculoskeletal pain since taking AIs and the score for the worst pain severity within 24 hours was 5.08±2.80 out of 10. Musculoskeletal pain, however, was not associated with AI continuation intention. Fear of cancer recurrence (FCR) was clinically significant (≥13) for 74.0% of the respondents (mean, 17.62±7.14). Musculoskeletal pain severity and pain interference were significantly associated with FCR (r=.21, p<.05; r=.35, p<.01, respectively). Pain interference was significantly associated with beliefs about endocrine therapy (r=-.18, p<.05). Conclusion: AI continuation intention can be modified by reinforcing patients' beliefs about endocrine therapy. Musculoskeletal pain may have a negative effect on beliefs about endocrine therapy and increase FCR among BCS. Thus, awareness of musculoskeletal pain during AI therapy should be raised and further research is required to develop multidisciplinary pain management strategies and clinical guidelines to reinforce beliefs about endocrine therapy.
