  • With the introduction of supply chain management concept, the nature of a firm is fundamentally changed. Control is no longer based on direct control of the business processes, but rather based on integration across member organizations in the supply chain. Firms are trying to achieve a competitive edge by managing their supply chain performance to gain advantages in cost and service differentiation. The supply chain elements of a sea port involves ILSP (Inbound Logistics Service Provider) at the input side and OLSP (Outbound Logistics Service Provider) at the output side. The goal of sea port is to satisfy the needs of different parties, both upstream and downstream, in the chain with greater effectiveness and efficiency than it's competitors. In this context, the purpose of this paper is to derive conceptualization of the SCP (Supply Chain Performance) in the sea port from literature review on the previous researches and to tackle their theoretical and practical implications. The paper deals with conceptualizing SCP in sea port using the SCOR (Supply Chain Operation Reference) model. It incorporates both the effectiveness and efficiency aspects of performance measurement. And it also recognizes customer related reasons for measuring performance.

  • High precision sensing is very important in various technologies. Especially, it is more important when it were applied to nano/micro meter level's sensing like AFM, storage, etc. And capacitive sensing is widely used method. To improve the measurement efficiency, many signal conditioners were studied and one of them was surface acoustic wave (SAW) device. SAW device is very widely used as a high frequency bandwidth filter. Due to the reflective characteristic of high frequency, the response of SAW device contains both propagative and reflective signal at the external impedance. In this paper, we used SAW device as signal conditioner of capacitive sensor. And high precision gap measurement was executed using capacitive load. Reference signal was reflective SAW response and the magnitude at the center frequency of SAW device by the change of impedance was checked. Finally, the attainable gap resolution was determined.

  • Objectives: Load carrying tasks are recognized as one of the primary occupational factors leading to slip and fall injuries. Nevertheless, the mechanisms associated with load carrying and walking stability remain illusive. The objective of the current study was to apply local dynamic stability measure in walking while carrying a load, and to investigate the possible adaptive gait stability changes. Methods: Current study involved 25 young adults in a biomechanics research laboratory. One tri-axial accelerometer was used to measure three-dimensional low back acceleration during continuous treadmill walking. Local dynamic stability was quantified by the maximum Lyapunov exponent (maxLE) from a nonlinear dynamics approach. Results: Long term maxLE was found to be significant higher under load condition than no-load condition in all three reference axes, indicating the declined local dynamic stability associated with load carrying. Conclusion: Current study confirmed the sensitivity of local dynamic stability measure in load carrying situation. It was concluded that load carrying tasks were associated with declined local dynamic stability, which may result in increased risk of fall accident. This finding has implications in preventing fall accidents associated with occupational load carrying.

  • Attempts were to produce porcine leukocyte interferon(PorLeIF) and porcine immune interferon (PorIIF) in the culture of porcine leukocytes. The interferons produced were tested for antiviral activity against vesicular stomatitis virus on poreine-derived PK(15) cells, human-derived FL cells, and Korean native black goat-derived BGK cells. The results were summarized as follws: 1. In the isolation of porcine leukocytes, the mean isolation rate by the buffy coat separation method (28.7%) was higher than that by the hydroxyethyl starch-RBC sedimentation method (9.2%). 2. When NDV(BI)-induced PorLeIFs were assyed on PK(15) cells and FL cells, the mean titers were 129 IU/ml and 72 IU/ml respectively, being 55.8% of the activity in homologous species system expressed in heterologous system. 3. The activities of PHA P-induced PorIIFs were 197 IU/ml on PK (15) cells and no activity on human FL cells. The mean antiviral activity of PorIIF was 1.5 times that of PorLeIF in PK (15) cells. 4. The cytopathic effect of vesicular stomatitis virus was observed in BGK cells derived from Korean native black goat kidney permitting interferon assay on the cells. While the cross-species antiviral activity of reference human ${\alpha},\;{\beta}-interferon$ was observed on the cells, PorLeIF and PorIIF did not show any activity.

  • Scanning white-light interferometry is an important measurement option for many surfaces. However, serious profile measurement errors can be present when measuring free-form surfaces being highly curved or tilted. When the object surface slope is not zero, the object and reference rays are no longer common path and optical aberrations impact the measurement. Aberrations mainly occur at the beam splitter in the interference objective and from misalignment in the optical system. Both effects distort the white-light interference signal when the surface slope is not zero. In this paper, we describe a modified version of white-light interferometry for eliminating these measurement errors and improving the accuracy of white-light interferometry. Moreover, we report systematic errors that are caused by optical aberrations when the object is not flat, and compare our proposed method with the conventional processing algorithm using the random ball test.

  • We measured the surface flatness of both sides for refractive media using the transmitted digital holography method. To enhance the accuracy of the result, phase-shifting system was used. With two different phase modulation of reference beam, the phase profile of object can be easily obtained. Thus, we proposed the surface measurement method which can measure large area fast, compared with conventional methods. To guarantee the reliability of obtained result, we compared with Zygo measurement system. With the proposed method, the surface flatness of $3.45{\mu}m$ resolution could be obtained.

  • This study aims to analyze the effect of transformational leadership (TL), procedural justice (PJ), and training (T) on employee performance (EP) mediated by self-efficacy (SE). The object of this research is Rumah Sakit Umum Daerah (RSUD) M.Th. Djaman, a hospital in Sanggau Regency, while the subjects are the institution's staff. Data collection search uses purposive sampling with a total of 120 samples. Data are obtained through questionnaires distributed directly to respondents using the Google Form application. Data analysis techniques used in this study include standard error of mean (SEM) with AMOS software version 24.00. Methods use to test validity and reliability of data include Confirmatory Factor Analysis (CFA), Construct Reliability (CR) and VE. The results of the analysis show that only training has a significant effect on self-efficacy, and self-efficacy has a significant effect on employee performance. Also, self-efficacy is proven to mediate the role of training on employee performance; the other hypotheses are not significant. Training is the most prominent positive factor affecting self-efficacy and self-efficacy has a significant effect on employee performance at RSUD M.Th. Djaman. The results of this study can be used as a reference by management in determining what policy priorities should take precedence.

  • This scholarly work is an effort to capture the effects of oil prices on the actual exchange rate between dollar and rupee. This is done with reference to the U.S. dollar as oil prices are marked in USD (U.S. Dollar) in the international market, and India is among the top five importers of oil. Using monthly data from January 2001 to May 2020. The study used the real GDP, money supply, short-term interest rate difference between two countries, and inflation apart from the crude oil prices per barrel as the factors that help define the exchange rate. The analysis, through cointegration and vector error correction method (VECM), suggests long and short-run causality amid prices of oil and the rate of exchange fluctuations. Oil prices are found to be negatively related to the exchange rate in the long term but positively related in the short term. The result of the Wald test also indicates the short-run causation from the short-term interest rate and the prices of crude oil towards the exchange rate. The present study shows that oil prices are evidence of the existence of short-term and long-term driving associations with short-term interest rates and exchange rates.
