Sales representatives of automobile company play a key role in the circulation system. Given the characteristics of the good, consumers demand high-quality information and guides from the salespersons when they decide to purchase an automobile. Sales representatives provide service to the customers in accordance with their needs to help purchase decision-making process. Therefore, a sales representative's personal competence have a significant effect on sales performance. Based on this hypothesis, we assumed that personal competence of a salesperson has a positive correlation with sales performance. An empirical analysis was conducted to test the hypothesis. This study classifies personal competence into 4 independent variables((1) sales technique professionalism (2) salesperson's attitude and relationship with customers (3) emotion utilization (4) emotion control) and measures the correlation with the dependent variable(sales performance). To verify the relationship, we set and modified the hypothesis based on the precedent studies and researches. In addiction, a survey was conducted targeting 300 local salespersons from Gyeonggi-Gangwon region. 268 valid samples were used and analyzed with SPSS WIN24.0 statistical program. As a result of an empirical analysis, it turned out that sales technique professionalism and emotion utilization have positive correlation with sales performance. However, the result failed to support the assumption that sales representative's attitude and relationship with customers and emotion control have positive correlation with sales performance. At last the result revealed that personal competence should be considered as an important determinant of recruitment specification for sales representatives.

Purpose: The Korean government has tried to decrease the suicide death rate over the last decade. Suicide attempts, particularly non-fatal attempts, are the most powerful known risk factor for a completed suicide. An analysis of suicide attempt methods will help establish the effective preventive action of suicide. Fit prevention according to the method of suicide attempt may decrease the incidence of suicide death. Self-poisoning is suggested as a major method of both suicide attempts and suicide death. The aim of this study was to determine if a self-poisoning patient is a suitable target for the prevention of the suicide. Methods: This was retrospective analysis of a prospective cohort, which included patients who presented to the emergency department (ED) after a self-harm or suicide attempt from Jan 2013 to Dec 2017. The proportion of methods in suicide attempts, psychological consultation, and fatality according to the suicide attempt method were analyzed. The types of poison were also analyzed. Results: Poisoning was the most common method of suicide attempts (52.1%). The rate of psychological consultations were 18.8% for all patients and 29.1% for poison patients (p<0.001). The rate of mortality in poisoning was 0.6%. Psychological consultation was performed more frequently in admission cases than discharged cases. The most common materials of poisons was psychological medicines and sedatives that had been prescribed at clinics or hospital. Conclusion: Self-poisoning is a major method of suicide attempt with a high rate of psychiatric consultation, low mortality rate, versus others methods. The prevention of suicide death for suicide attempts may focus on self-poisoning, which is the major method of suicide attempts. A suitable aftercare program for self-poisoning may be an effective method for preventing suicide if an early diagnosis and management of psychiatric disorders through psychiatric consultation can be made, and early connection to social prevention program for non-fatal patients are possible.

According to the government's announcement of the safety management enhancement policy for small and medium-sized private construction sites, the subject of mandatory CCTV installation has been expanded from large construction sites to small and medium-sized construction sites. However, since the existing CCTV at construction sites has been used for simple control for safety management, so research is needed for monitoring of construction sites. Therefore, in this study, three vanishing points were calculated based on a single image taken with a monocular camera, and then a camera matrix containing interior orientation parameters information was determined. And the accuracy was verified by calculating the height of the target object from the height of the reference object. Through height determination experiments using vanishing points based on a monocular camera, it was possible to determine the height of target objects only with a single image without separately surveying of ground control points. As a result of the accuracy evaluation, the root mean square error was ±0.161m. Therefore, it is determined that the progress of construction work at the construction sites can be monitored through the single image taken using the single camera.

The purpose of this study is to present a new industrial land demand prediction method that can consider external economic factors. The analysis model used ARIMA-X, which can consider exogenous variables. Exogenous variables are composed of macroeconomic variable, Business Survey Index, and Composite Economic Index variables to reflect the economic and industrial structure. And, among the exogenous variables, only variables that precede the supply of industrial land are used for prediction. Variables with precedence in the supply of industrial land were found to be import, private and government consumption expenditure, total capital formation, economic sentiment index, producer's shipment index, machinery for domestic demand and composite leading index. As a result of estimating the ARIMA-X model using these variables, the ARIMA-X(1,1,0) model including only the import was found to be statistically significant. The industrial land demand forecast predicted the industrial land from 2021 to 2030 by reflecting the scenario of change in import. As a result, the future demand for industrial land was predicted to increase by 1.91% annually to 1,030.79 km². As a result of comparing these results with the existing exponential smoothing method, the results of this study were found to be more suitable than the existing models. It is expected to b available as a new industrial land forecasting model.

Background: The purpose of the study was to investigate the level of infection control and prevention awareness among dental practitioners in Korea based on the infection control and prevention guidelines of the Centers for Disease Control and Prevention (CDC) in the United States. Methods: A survey was created on 'Standard and Education on CDC Infection Control Standards', 'Matters related to CDC Infection Control Prevention', and 'Characteristics of Research Subjects and Infection Control Characteristics' based on the CDC Dental Infection Control List.' A total of 222 surveys were conducted and used for frequency and cross-tabulation analyses. Results: Most research participants worked at university or general hospitals, and 93.7% had received infection prevention education within the past year. The average awareness of the CDC dental infection control standards and education was 77.2 %, which was higher than previous research results. Preventive awareness was 71.5% on average, and there was a statistically significant difference in preventive awareness between the certified and non-certified evaluation groups (p<0.001). Conclusion: The participants of this study showed a higher awareness of infection control standards, education, and prevention than those in previous studies. However, this was insufficient compared with the CDC dental infection control standard prevention guidelines. Therefore, government agencies and related organizations must establish systematic infection control systems.

Background and Purpose: The efficacy and safety of GV1001 have been demonstrated in patients with moderate-to-severe Alzheimer's disease (AD). In this study, we aimed to further demonstrate the effectiveness of GV1001 using subscales of the Severe Impairment Battery (SIB), which is a validated measure to assess cognitive function in patients with moderate-to-severe AD. Methods: We performed a post hoc analysis of data from a 6 month, multicenter, phase 2, randomized, double-blind, placebo-controlled trial with GV1001 (ClinicalTrials.gov, NCT03184467). Patients were randomized to receive either GV1001 or a placebo for 24 weeks. In the current study, nine subscales of SIB-social interaction, memory, orientation, language, attention, praxis, visuospatial ability, construction, and orientation to name-were compared between the treatment (GV1001 1.12 mg) and placebo groups at weeks 12 and 24. The safety endpoints for these patients were also determined based on adverse events. Results: In addition to the considerable beneficial effect of GV1001 on the SIB total score, GV1001 1.12 mg showed the most significant effect on language function at 24 weeks compared to placebo in both the full analysis set (FAS) and per-protocol set (PPS) (p=0.017 and p=0.011, respectively). The rate of adverse events did not differ significantly between the 2 groups. Conclusions: Patients with moderate-to-severe AD receiving GV1001 had greater language benefits than those receiving placebo, as measured using the SIB language subscale.

We investigated consumer perceptions of and purchase intentions for health foods. Data were collected from 454 adults over the age of 20 years living in Seoul and Gyeonggi province, from May 10 to June 5, 2010. Those that "hardly ever drink" (41.4%) were most prevalent in terms of drinking activity, whereas 80.8% of respondents did not smoke. Also, those who responded "hardly ever exercise" ranked highest; although 43.8% in fact exercised frequently. Of all respondents, 44.5% admitted to suffering slightly from stress. A total of 59.5% of respondents opined "I am healthy but I do worry about health", and "exercise" topped the list of approved (37.2% of respondents) health care methods. We also found that 83.5% of respondents claimed to have tried health foods, whereas in the case of having no taking experience, 60% had not purchased such foods because, in their view, this was unnecessary. The extent of concerns about health foods scored 3.09, and the level of purchase intentions for health food was high, with a score of 3.40. Therefore, all of government, producers, distributors, and academic researchers must provide consumers with accurate and complete information, and need to collaborate in the development of consumer education programs on health foods. This will enhance consumer interest in such foods, and empower logical choices.

Inductively Coupled Plasma Dynamic Reaction Cell Quadrupole Mass Spectrometry (ICP-DRC-QMS) was characterized for the detection of the six naturally occurring calcium isotopes. The effect of the operating conditions of the DRC system was studied to get the best signal-to-noise ratio. This experiment shows that the potentially interfering ions such as $Ar^+$, ${CO_2}^+$, ${NO_2}^+$, $CNO^+$ at the calcium masses m/z 40, 42, 43, 44 and 48 were removed by flowing $NH_3$ gas at the rate of 0.7 mL/min $NH_3$ as reactive cell gas in the DRC with a RPq value (rejection parameter) of 0.6. The limits of detection for $^{40}Ca$, $^{42}Ca$, $^{43}Ca$, $^{44}Ca$, and $^{48}Ca$ were 1, 29, 169, 34, and 15 pg/mL, respectively. This method was applied to the determination of calcium in synthetic food digest samples (CCQM-P13) provided by LGC for international comparison. The isotope dilution method was used for the determination of calcium in the samples. The uncertainty evaluation was performed according to the ISO/GUM and EURACHEM guidelines. The determined mean concentration and its expanded uncertainty of calcium was ($66.4{\pm}1.2$) mg/kg. In order to assess our method, two reference samples, Riverine Water reference sample (NRCC SLRS-3) and Trace Elements in Water reference sample (NIST SRM 1643d), were analyzed.
