  • It is difficult but very necessary to measure the productivity of container terminals as logistics service provider. It is meaningful to find the appropriate inputs and outputs of the logistics service delivery systems and to measure the relationship between these inputs and outputs. This study proposes a model of evaluating the efficiency of container terminals. The evaluation consists of three phases. First, DEA(Data Envelopment Analysis) phase, determines the efficiency score and weights of DMUs(Decision Making Unit). This phase performs through four steps : selection of DMU, selection of DEA model, determination of input and output factors, calculation of efficiency score and weights for each DMU. Secondly, CEM (Cross Evaluation Model) phase, is to calculate the cross-efficiency scores of DMUs. This phase performs through three steps: selection of CEM, determination of cross-efficiency score for each DMU and development of cross-efficiency matrix. Finally, average cross-efficiency analysis phase is to compute the average cross-efficiency score. The proposed model discriminates among DMUs and ranks DMUs, whether they are efficient or inefficient.

  • Because of unpredictability and high possibility of abnormal results by clinical trials compared to general medical behaviors, a procedure for ensuring with sufficient explanations by investigators must be secured. Therefore, in a sequence of clinical trials, what kinds of scope, stage, and method of explanations provided by investigators, including doctors or researchers, to trial subjects are closely related to the compensation for damages by violation of liability for explanation. In case of application of clinical trials to patients who have critical illness such as cancer, issues of "Quality of Life" regarding trial subjects, cancer patients, should be discussed. Especially, in case of clinical trials for terminal cancer patients, the right of subjects' self-determination, which is a fundamental principle in medical behaviors, should be discussed. The right of self-determination includes participation in clinical trials for the possibility of life-sustaining even a little bit, or no participation in clinical trials in order to have a time for completing the rest of his life. Like this, if the extent and scope of explanations related to the issues of "Quality of Life" are raised as main issues, the evaluation of "Quality of Life", should be a prerequisite. In many occasions, realistically, despite bad results such as deaths or serious adverse drug reactions after clinical trials, it may not be easy for compensating to trial subjects or their survivors, who requested civil compensation for damage. Futhermore, in abnormal results after concealment of clinical trials or performance of clinical trials without permission, and in the case of trial subjects' failures of proving proximate cause between the clinical trials and abnormal results, problematic results such as no protection to the trial subjects could be occurred. In performing clinical trials, investigators should provide sufficient explanations for trial subjects and secure voluntary informed consents from the trial subjects. Therefore, clinical trials without trial subjects' permissions and the informed consent process violate trial subjects' rights of self-determination, and the investigators shall be liable for compensation for damages. Then, issues might be addressed are what are essential contents of patients' "rights of self-determination" infringed by clinical trials without subjects' permissions. Two perspectives about patients' rights of self-determination might be considered. One perspective regards physical distress of patients (subjects) from therapies without sufficient explanations as the crux of the matter. The other perspective regards infringement of human dignity caused by being subjects without permission as the crux of the matter irrespective of risks' big and small influences. This research follows perspective of the latter. Forming constant fiduciary relation between investigators (doctors) and subjects (patients) pursuant medical contracts, and in accordance with this fiduciary relation, subjects, who are patients, have expectations of explanations and treatments by the best ways. If doctors and patients set this forth as a premise, doctors should assume civil liability when doctors infringe patients' expectations.

  • This study aims to analyze the relationship of e-HRM implementation to employee performance both directly and indirectly through the intervening of the Human Resource service Quality variable, both practically and theoretically. This study uses variance-based structural equation modeling (SEM) techniques with partial least square (PLS) statistical testing tools to test the direct relationship of e-HRM and the performance and relationship moderated by Human Resources service quality tested on 200 civil servants in five offices under the coordination of the Government of the South Sulawesi Province of Indonesia. The data collection model in this study uses an online survey. The data analysis stages through the explanatory concept consist of, first, the interpretation of the distribution of the average frequency of respondents' answers; second, outer-loading; third, determination of the validity and reliability; fourth, the coefficient of determination test and partial test; fifth, the GoF model; sixth, validity test; and seventh, hypothesis testing. This study explores four hypotheses in a comprehensive fashion; the results of this study show that all hypotheses have positive and significant effects both through direct and intervening relationships. Among the three direct relationships, the relationship of e-HRM variables on HR Service Quality is greatest and most dominant.

  • Acetaminophen (N-acetyl-p-aminophenol) is one of the most popular analgesic and antipyretic drugs. An isotope dilution mass spectrometric method based on LC/MS was developed as a candidate reference method for the accurate determination of acetaminophen in pharmaceutical product. After spiking an isotope labeled acetaminophen (acetyl-$^{13}C_2$, $^{15}N$-acetaminophen) as an internal standard, tablet extracts were analyzed by LC/MS in a selected reaction monitoring (SRM) mode to detect ions at m/z $152{\rightarrow}110$ and m/z $155{\rightarrow}111$ for acetaminophen and acetyl-$^{13}C_2$, $^{15}N$-acetaminophen, respectively. The repeatability and reproducibility of the developed ID/LC-MS method were tested for the validation and assessment of metrological quality of the method.

  • Recently, service quality must reflect several demands of customers who show rapid and various changes so as to be compared with the past. So, objective and rapid measuring methods for service quality are necessary. For them, first of all, service company must calculate their standard of service quality accurately by measuring service quality exactly. Kano classified the degree of influence that is the degree of correspondence of the quality attributes of products and services to the subjective satisfaction of customers. As a result, the types of qualities are classified as attractive, must be, one dimensional, and indifference attributes. They have been widely used quality attributes in various industrial fields up to now. However, Kano model has a limit that it ignores the characters of the next frequent numbers even though there are not much gap comparing to the most frequent number in the questionnaire answers. The limit is attributed to the character of Kano model that the most frequent number is accepted as the only quality character. Timko calculated the customer satisfaction coefficient by using Kano's method and studied the differences in quality character by classifying the quality characteristics in a graphical way through the relationship between the satisfaction and the dissatisfaction coefficient. In this study, we used the quality level determination method of the 7-point Likert scale, which takes the weight into account, to complement the deficiencies of the existing Kano model. We also developed and applied a Potential Satisfaction Level (P) and Potential Customer Demand Improvement (PCDI) Index to present a new approach to the determination of service quality attributes. To measure the level of potential service satisfaction and to understand the degree of improvement, we collected specimens of 51 participants who has been trained in the National Strategy Business Training Program, which has been managed by government agent, and analyzed the results.
