SMEs manufacturing Factory, which are small-scale production systems of various types, mass-produce and sell products in order to meet customer needs. This means that the company has an excessive amount of material supply to reduce the loss due to lack of inventory and high inventory maintenance cost. And the products that fail to respond to the demand are piled up in the management warehouse, which is the reality that the storage cost is incurred. To overcome this problem, this paper uses ARIMA model, a time series analysis technique, to predict demand in terms of seasonal factors. In this way, demand forecasting model based on economic order quantity model was developed to prevent stock shortage risk. Simulation is carried out to evaluate the effectiveness of the development model and to demonstrate the effectiveness of the development model as applied to SMEs in the future.

With property values of buildings rising, interior construction works are also increasing globally. Interior construction technology has developed into building information modeling(BIM) that can estimate and integrate material quantities. Two-dimensional(2D) drawings and three-dimensional (3D) modeling are becoming a trend owing to the demanding on-site cost and process. 2D drawings and 3D modeling have both advantages and disadvantages that give rise to defects during interior construction work. The field problems, 2D drawings, 3D modeling, and preliminary risk factors of interior construction work were analyzed to identify real problems. Based on the problem analysis, various problems were derived, such as (1) communication with purchasers, (2) communication with workers, and (3) comprehension of the drawings. In this study, a checklist for quality improvement of interior construction was proposed to address the aforementioned issues.

Objectives: It has been pointed out that there are problems in handling and managing chemicals due to trade secrets of Material Safety Data Sheet(MSDS). To date, some company intentionally leave out of several parts and use an inaccurate expression in MSDS. In particular, with the result of the inspection of the government and labour community, it is required that the 2nd section in MSDS included the composition and information on ingredients has to be provided with comprehensive expression to secure more reliability. Methods: Therefore, this study is aimed: 1) to recognize the current status of trade secrets of MSDS in workplaces with both domestic manufacturers of chemical products and multinational corporations; 2) to make contributions to prevention of the industrial accidents by providing the accurate information of MSDS; 3) to improve the risk communication system related with chemicals; 4) to impress workers on the importance of right of known for MSDS. With the result we analyzed the status of trade secrets in MSDS in 73 companies, such as petrochemistry production, paint production, metal processing oil production, detergent production, and international company related with chemicals, we have found that 38,150 (45.5%) have the trade secrets parts in the total number of 83,832 in MSDS. Also, based on the 288 MSDS gathered by the Occupational Safety and Health Research Institute (OSHRI) from 2005 to 2009, 41.7% of the MSDS are classified into the trade secrets. Conclusions: Therefore, to procure an assurance system of MSDS, we suggest that a MSDS picking up and checking system be legislated in the Occupational Safety and Health Act to protect workers from the unidentified chemical hazards due to the secret trade of MSDS.

Prostate cancer is a leading cause of cancer death in American men and evidences point to significant life style/diet components as risk factors for its development or prevention. Two large cohort studies have identified the consumption of tomatoes or high Plasma levels of Iycopene as associated with reduced risk. A number of other substances such as quercetin, phytoene, phytofluene, cyclolycopene, salicylates and tomatine in tomato besides lycopene could have anticancer activity and may be acting synergistically with lycopene. Lycopene at almost physiologically feasible concentrations, reduces cell viability by cell cycle arrest and apoptosis and modulates the cyclin pathways as well as increasing intercellular communication. However, it is not clear whether lycopene or its oxidation products are more bioactive. Tomato product supplementation results in plasma accumulation of phytoene, Phytofluene, the lycopene oxidation product, and cyclolycopene at significant concentrations and lycopene supplementation, either as a tomato product or as beadlets, results in maximal mean plasma lycopene concentrations of ∼ 1 $\mu$M which is at the lower limit of its activity in cell culture. Rats and mice are poor accumulators of lycopene and other carotenoids making them poor models for the study of cancer prevention and control. Of the 19 animal studies for various cancer sites, lycopene showed a positive effect in 10 studies but negative in 2 prostate cancer studies. In vivo prevention of leukocyte DNA damage in humans has been mostly studied using tomato product supplementation but lycopene supplementation appeared to reduce oxidative DNA damage as well as tomato product supplementation. Lycopene appears to be bioactive in intefering with carcinogenesis but the actions of phytoene, phytofluene or cyclolycopene cannot be ruled out since these compounds were present in most of the lycopene material used for these studies. Although lycopene remains as a promising agent, especially for cancer control, exploring interactions with other tomato phytochemicals and with current prostate cancer therapies should be encouraged.

Background: Pulmonary atresia with intact ventricular septum(PA/IVS) is an anatomically heterogenous anomaly with a variety of surgical strategies possible. The purpose of the study is to evaluate the influence of right ventricular size on the early and midterm results of surgical repair of PA/IVS. Material and method: Medical records of 20 consecutive patients with PA/IVS operated on between January 1993 and August 1999 were retrospectively reviewed. There were 12 boys and 8 girls whose ages ranged from 2 days to 14.5 months (median 6 days). Their body weight ranged from 2.52kg to 9.35 kg(median 3.18kg). The preoperative Z-value of the diameter of the tricuspid valve(T-valve) was less than or -4 in 5 patients, between -4 and -2 in 1, between -2 and 0 in 7, between 0 and 2 in 6, and greater than or 2 in 1. All patients who had z-value of tricuspid valve greater than -2.05 were attempted biventricular repair(n=15) and all patients who had it smaller than -4.4 underwent systemic-pulmonary shunt operation only(n=3) or bidirectinal cavopulmonary shunt with right ventricular reconstruction(n=2). Result: Two early deaths(2/20, 10%) occurred. Both were infants who underwent transannular patch with shunt. One of these two had huge right ventricle(Z-value of tricuspid valve = 5). There were 2 late non-cardiac deaths 3 and 7 months after operations respectively. Follow-up was completed in all children at a mean of 35.3 months(range, 5 to 54 months). 10 of 11 survivors who underwent transannular patch or valvotomy with or without shunt procedure were in NYHA functional class I even though some of them had small interatrial communication or patent shunt. All three patients who had shunt procedure only at initial palliation completed Fontan procedures with no death. Two patients who underwent right ventricular outflow reconstruction with bidirectional cavopulmonary shunt were also in good condition. Conclusion: The transanular RVOT patch or valvotomy with or without systemic-pumonary shunt as an initial palliative procedure to achieve biventricular repair for the patients who had neither too small nor too large right ventricle(-2.05$\leq$Z-value of T-value of T-valve$\leq$2) could be performed at low operative risk(1/14 7.1%). Systemic-pulmonary shunt procedure and bidirectional cavopulmonary shunt procedure for the patients who had small right ventricle(Z-value of T-valve$\leq$4.4) could be also performed with low risk. But a patient with huge right atrium and ventricle(Z-value of t-valve=5) had poor operative result.

Safety accidents, called industrial accidents in construction work, are causing a lot of casualties, property damage and social controversy in the event of an accident, causing the construction to lose public confidence. The risk of safety accidents at construction sites may continue to increase as the construction of high-rise, large-scale, and multi-purpose complex buildings has increased in recent years. In particular, the most frequently constructed apartment construction among reinforced concrete buildings is designed and constructed with a wall-like structure with no beams for each floor, while the lower floors are made of lamen with columns and beams. As a result, the transfer beam or transfer slab to withstand the upper load is installed on the upper part of the Ramen structure, so the system Dongbari, which is installed as a temporary material during concrete laying construction, may collapse at any time during plowing and curing. The purpose of this study is to apply IT convergence technology to prevent the collapse of the system Dongbari during concrete installation, and to apply many of the variables that may occur during construction on a case-by-case basis to check the stability of the system Dongbari and to propose a model of the anti-conducting prediction system.

The purpose of this study is to explore the anti-smoking message effects and smoking status on smoking belief attributes. Based on the health behavior theories such as theory of reasoned action, health belief model, and social cognitive theory, three factors are selected to investigate the effects of anti-smoking campaign messages. The balance of benefits and barriers, self-efficacy, and social pressure are selected as independent variables. Three two-way ANOVA were conducted. Results showed that the main effect of social pressure were found with the social smoking attributes. Interaction effects were found on the nonsmoker-social pressure group and the non-smoker-two sided message group. It is found that nonsmokers accepted these two anti-smoking messages easily as compared to smoker groups. No main smoking status was found in this study; it is believed that smoking is a habitual that is not changed easily because attitude formation takes time. Results revealed that the two-sided message video releases and the social pressure video releases were favored by both smokers and nonsmokers. This study contributes the theoretical framework that can be transferred to the practices of anti-smoking campaign. Also, the researcher produced the televised stimuli which is not common in health message studies. By using the televised message material, the research tried to solve the validity problem which is common in experimental design.

The underground utilities installed under the ground is an important civil engineering structure, such as water supply and sewerage pipes, underground power lines, various communication lines, and city gas pipes. Such underground utilities can be exposed to risk due to external factors such as concentrated rainfall and vehicle load, and it is important to select and construct an appropriate backfill material. Currently, a method mainly used is to fill the soil around the underground utilities and compact it. But it is difficult to compact the lower part of the buried pipe and the compaction efficiency decreases, reducing the stability of the underground utilities and causing various damages. In addition, there are disadvantages such as a decrease in ground strength due to disturbance of the ground, a complicated construction process, and construction costs increase because the construction period becomes longer, and civil complaints due to traffic restrictions. One way to solve this problem is to use a liquid filler. The liquid filler has advantages such as self-leveling ability, self-compaction, fluidity, artificial strength control, and low strength that can be re-excavated for maintenance. In this study, uniaxial compression strength test and fluidity test were performed to characterize the mixed soil using marine clay, stabilizer, and in-situ soil as backfill material. A freezing-thawing test was performed to understand the strength characteristics of the liquid filler by freezing, and in order to examine the effect of the filling materials on the corrosion of the underground pipe, an electrical resistivity test and a pH test were performed.
