This paper is structured into three main parts and a conclusion. The main section provide definitions of efficiency, effectiveness and performance in terms of the distribution channel, followed by a review of related performance measurement, before discussing difficulties of measurement. According to the theoretical approach, it appears that key theroretical issues are centered around customer service, logistics excellence, time compression, the use of IT, and a move towards integrated logistics. The empirical approach shows that in the past, various financial performance indicators were regarded as relevant management information. However, today, management needs additional performance indicators. Therefore, external assessments of effectiveness must be performed to measure customers' satisfaction with the physical flow of product through the distribution channel network. So, what is needed is to take previous normative and explorative research and progress through a framework by developing valid measures of distribution channel's effectiveness and efficiency, and identifying research methodologies suited to the data collection requirements.

Currently, many universities are implementing software-oriented universities and artificial intelligence-oriented universities to foster software-oriented manpower. We are educating students to design and produce computational thinking and coding directly with their major knowledge. However, computer education is not easy for non-majors, and there are many difficulties in coding. The results of responses from 104 students from the College of Health Sciences and College of Social Management who took the liberal arts computer at University H were analyzed using SPSS 26.0 version. In the liberal arts computer class for non-majors, a PJBL-based class plan was proposed. The effectiveness of PJBL-based classes was confirmed through a questionnaire for the improvement of artificial intelligence liberal arts courses. As a result, PJBL-based education showed statistically significant results in terms of satisfaction, effectiveness, and self-efficiency of classes regardless of major.

This study is designed to evaluate the effectiveness of TDM as a peak-period trip reduction strategy. This effort uses as a case study, the implementation of Regulation XV (REGXV) in Southern California, the most ambitious and far reaching employer-based ridesharing program implemented to date. This study explores the program effectiveness in terms of three aspects ; employee travel behavior changes after implementating Regulation XV, TDM programs offered by employers subjects to Regulation XV, and causal relationship between employee travel behavior changes and employer-based TDM programs. The study finds that Regualtion XV has a small, but statistically significant positive impact on AVR change. Popular incentives used by employers are less costly and easy to implement rather than to be effective. The increase in AVR is associated with increases of carpools promoted by strong incentives such as monetary subsides. A large number of indirect incentive programs are not effective. The study concludes that employers need to invest heavily on strong incentives, rather than on proposing diverse incentives, to comply with REGXV.

The purpose of this study is to assess the effectiveness of a parental education program developed to 295 single university students based on pre-test and the post test on the program. The data is interpreted using statistical methods such as the Percentage, T -Test, Anova test, and the Turkey test. The major results were as follows : First, significant difference regarding the knowledge on parenthood existed among students before and after the tests, with the post-test students showing more knowledge on the matter. Among the six sub-categories of parenthood education program, the effects of the post-testing were most visible in pregnancy, delivering, pre-natal and infant development, parents attitude, and sex education for their children in the form of increased awareness and knowledge. However, no significant effects were detected in pre-natal education. In terms of socio-demographic variable, effects were more visible in female students than in male students. Second, the program also resulted in positive effects in both male and female students.

Underfloor air distribution system is generally known to be more energy-saving and provide more comfort as compared with overhead air distribution system. In practice, however, some buildings to which underfloor air distribution system is applied have less effectiveness in saving energy and are getting dissatisfaction with cold draft caused by wind velocity of air distribution in terms of comfort. It is judged that such problems are due to failure to consider properties of underfloor air distribution system in applying it and identical design with the design standards for the existing overhead air distribution system. This study aims at introducing an air conditioning type of the occupied zone for underfloor all distribution system to see its effectiveness in saving energy for air conditioning of the occupied zone through a comparative simulation with the existing air conditioning type.

Purpose: The purpose of this study was to identify the teaching effectiveness and adequacy of practical training in nursing students. Methods: This descriptive research was conducted using a convenience sampling. The sample consisted of 619 nursing students with experience in practical training among five colleges, located in four cities. The data collection was performed using self-reported questionnaires. Research tools, developed by Kim (1996), were used to measure the effectiveness of clinical instructors and the adequacy of practical training developed by researchers. The data was analyzed using SPSS 20.0. Results: The average of teaching effectiveness was 3.43 (out of 5) and adequacy of practical training was 3.33 (out of 5). Teaching effectiveness and adequacy of practical training showed a significant positive correlation (r=.74, p<.001). Teaching effectiveness and each sub-area: adequacy of practical training, practical contents (r=.59, p<.001), practical attitude (r=.45, p<.001), practical instructor (r=.62, p<.001), practical environment (r=.46, p<.001), and practical evaluation (r=.64, p<.001), revealed a significant positive correlation. Conclusion: Nursing students prefer the actual training from professors who are more professional and clinical experienced. Professors presenting the theory lectures should also be aware of clinical practice so that education can be more professional and effective in terms of clinical practice.

BACKGROUND/OBJECTIVES: This study was designed to provide scientific evidence on the effectiveness of worksite-based dietary intervention to reduce obesity among overweight/obese employees. MATERIALS/METHODS: Electronic search was performed using Ovid Medline, Embase, Cochrane Library, and CINAHL databases. The keywords used were "obesity," "nutrition therapy," and "worksite." The internal validity of the randomized controlled trials (RCTs) was assessed using the Cochrane's Risk of Bias. Meta-analysis of selected studies was performed using Review Manager 5.3. RESULTS: A total of seven RCTs with 2,854 participants were identified. The effectiveness of dietary interventions was analyzed in terms of changes in weight, body mass index (BMI), total cholesterol, and blood pressure. The results showed that weight decreased with weighted mean difference (WMD) of -4.37 (95% confidence interval (CI): -6.54 to -2.20), but the effectiveness was statistically significant only in short-term programs < 6 months (P = 0.001). BMI also decreased with WMD of -1.26 (95% CI: -1.98 to -0.55), but the effectiveness was statistically significant only in short-term programs < 6 months (P = 0.001). Total cholesterol decreased with WMD of -5.57 (95% CI: -9.07 to -2.07) mg/dL, demonstrating significant effectiveness (P = 0.002). Both systolic (WMD: -4.90 mmHg) and diastolic (WMD: -2.88 mmHg) blood pressure decreased, demonstrating effectiveness, but with no statistical significance. CONCLUSIONS: The worksite-based dietary interventions for overweight/obese employees showed modest short-term effects. These interventions can be considered successful because weight loss was below approximately 5-10 kg of the initial body weight, which is the threshold for the management of obesity recommended by the Scottish Intercollegiate Guideline Network (SIGN).

In this study, a series of geotechnical centrifugal tests were conducted to investigate the effectiveness of settlement control of two types of rigid pile structure embankments (PRSE) in collapsible loess under high-speed railway embankments. The research results show that ground reinforcement is required to reduce the post-construction settlement and settlement rate of the embankments. The rigid pile structure embankments using rigid piles can substantially reduce the embankment settlement in the construction of embankments on collapsible loess, and the efficiency in settlement reduction is affected by the pile spacing. The pile-raft structure embankments (PRSE) have much stronger ability in terms of the effectiveness of settlement control, while the pile-geogrid structure embankments (PGSE) provides rapid construction as well as economic benefits. Rational range of pile spacing of PRSE and PGSE are suggested based on the requirements of various railways design speeds. Furthermore, the time effectiveness of negative skin friction of piles and the action of pile-cap setting are also investigated. The relevant measures for improving the bearing capacity and two parts of transition zone forms as positive control mean have been suggested.

Relating to grasping sequential landscape characteristics in consideration of the behavioral characteristics of the subject experiencing visual perception, this study was made on the subject of main walking line section for visitors of three treasures of Buddhist temples. Especially, as a method of obtaining data for grasping sequential visual perception landscape, the researcher employed [momentum sequential viewpoint setup] according to [the interval of pointers arbitrarily] and fisheye-lens-camera photography using the obtained omni-directional angle visual perception information. As a result, in terms of viewpoint selection, factors like approach road form, change in circulation axis, change in the ground surface level, appearance of objects, etc. were verified to make effect, and among these, approach road form and circulation axis change turned out to be the greatest influences. In addition, as a result of reviewing the effectiveness via the subjects, for the sake of qualitative evaluation of landscape components using the VR picture image obtained in the process of acquiring omni-directional angle visual perception information, a positive result over certain values was earned in terms of panoramic vision, scene reproduction, three-dimensional perspective, etc. This convinces us of the possibility to activate the qualitative evaluation of omni-directional angle picture information and the study of landscape through it henceforth.
