  • According to the recent increase in the height of supertall buildings, construction lift became one of most important equipment for vertical transportation of resources. However, increase in lifting load during peak time in which the resources are concentrated often causes a risk of construction delay. This study suggests a concept of Double-Cage construction lift, which is a lift with two cages attached together allowing transportation of resources on two consecutive work floors simultaneously. The aim of this study is to present a simulation model suitable for calculating hoisting time of Double-Cage construction lift. The proposed model is expected to be utilized when applying Double-cage construction lift for its efficient operation and management.

  • The International Ship and Port Facility Security (ISPS) Code which was developed as the main response of the shipping sector to the miserable event of 11 September 2001 came into effect on 1 July 2004. The ISPS Code designed to detect and eliminate security threats affecting ships and port facilities used in international trade will significantly impact not only on the management and operation of the shipping industry but also on maritime law despite the fact that it is the regulatory framework of public law. It is expected that implementing the ISPS Code will contribute to reinforcement of maritime security on the one hand. However, on the other hand, more intensified security inspection and control measures of port states will also cause delay and additional costs which cause uncertainty in allocating security risk and cost between the contracting parties. Therefore, it is desire to insert new security clause dealing with main security issues or adapt existing clauses to new shipping environments to minimize disputes.

  • Purpose: To investigate the rate of questionable development in infants born prematurely and explore factors affecting developmental delays. Method: The participants were 46 infants born prematurely being seen in one of two urban health centers. A questionnaire and the HOME checklist were used to collect data, and the Korean Denver II developmental screening test was administered. Results: Of the participants 21.7% were classified as having questionable development. The only variable with a significant difference between the two groups was acceptance in the HOME checklist. Psychosocial factors such as mothers' burden, depression, family functioning, and social support were not significantly different between the two groups. Conclusion: An early developmental screening test for prematurely born infants is needed. Also, the childrearing environment was identified as a significant factor in infants' development. These findings suggest that HOME score might be useful for identifying infants at risk for developmental delays and interventions for these infants will probably be more effective if their mothers can provide a more appropriate social environment. Further studies are suggested with larger samples.

  • Right-sided diaphragmatic rupture is less common and more difficult to diagnose than left-sided lesion. It is rarely combined with the herniation of the abdominal organs into the thorax. High level of suspicion is the key to early diagnosis, and a delay in diagnosis is implicated with a considerable risk of mortality and morbidity. We experienced a case of right-sided diaphragmatic rupture combined with complete avulsion of the right kidney and herniation of the liver into the thoracic cavity.

  • In Korea, diabetes mellitus, which causes micro and macrovascular complications, has been rapidly increasing during recent decades and has become a leading cause of disability-adjusted life years. The prevalence of diabetes mellitus was 12.4% in 2011 and that of prediabetes, a condition of high risk for developing diabetes mellitus, is 1.5- to 3-fold greater than that of diabetes. The diabetes prevention programs in other countries were shown to reduce or delay progression from prediabetes to diabetes mellitus. However, these results are not applicable to Korean people because of genetic and environmental differences. Therefore, we need to plan and perform a diabetes prevention study in Korean. Based on these results, we should design intervention tools for a Korean diabetes prevention program. We can consider several preventive interventions with lifestyle modification suitable for Korean people and pharmacologic treatments such as metformin or alpha-glucosidase inhibitor.

  • The prevalence of developmental disabilities is increasing worldwide over time. Developmental issues in infancy or early childhood may cause learning difficulties or behavioral problem in school age, further adversely affecting adolescent quality of life, which finally lead to low socioeconomic status in family, increase in medical expenses, and other relevant issues in various ways. Early childhood has brain plasticity, which means there is a high chance of recovering from developmental issues by early detection and timely intervention. Pediatricians are placed an ideal position to meet with young children till 6 years of age, of which age range is the time applicable to early intervention. Determining child's developmental status can be made by 2 pathways such as developmental surveillance and developmental screening tests. For better results, pediatricians should update their knowledge about developmental issues, risk factors, and screening techniques through varying educational program or other relevant educating materials. This paper will update reports on the prevalence of developmental disabilities and review the recent results of the Korean developmental screening test and discuss relevant issues. Finally, it will be addressed the pediatrician's role in early detecting developmental issues and timely intervention.

  • Implementation of disease-warning systems often results in substantial reduction of spray frequency (Lorente et al., 2000; Madden et al., 2000). This change reduces the burden of pesticide sprays on the environment and can also delay the development of fungicide and bactericide resistance. To assess the risk of outbreaks of many foliar diseases, it is important to quantify leaf wetness duration(LWD) since activities of foliar pathogen depend on the presence of free water on host crop surface for sufficient periods of time to allow infection to occur.(omitted)

  • In order to minimize casualties in case of a fire in a building, it is necessary to anticipate the time required for evacuation of occupants and the delay in evacuation in advance, and prepare countermeasures for possible occurrences. In fact, various factors that cannot be predicted exist and cannot be considered by excluding them, so the risk is predicted and evaluated through quantitative evacuation modeling. In order to understand this, we analyzed domestic and international evacuation modeling research trends. For about 40 years, starting with the characteristics of human movement, an evacuation modeling technique based on scientific methods has been developed through actual fire accident cases and various real-world experiments with humans. Then, in order to analyze the natural reaction of humans, which has a decisive influence in the recognition and decision-making phase, evacuation modelling studies have been conducted in depth using psychological and physical experimental methods.

  • The U.S. Department of Health and Human Services and fifteen other Federal Departments and Agencies have issued final revisions to the Federal Policy for the Protection of Human Subjects (the Common Rule, 45 CFR 46, Subpart A). The Common Rule was initially promulgated in 1991 and amended in 2005. The Final Rule to update the current regulations was published in the Federal Register on 19 January 2017. The final compliance date of the revised Common Rule including the cooperative research requirement is effective on 20 January 2020 after twice to delay. The revised Common Rule aims to make more effective conduct of minimal risk research reflecting modern research activities and recognize evolving technologies, including mobile technologies, internet, and the growth in computing power. The revisions to the Common Rule were based on a variety of sources of public, stakeholder, and expert comments. The author summarized the key changes and the implications to Korean human research regulations.

  • Floats are used by the parties involved in a construction project. The owner may use float by changing order(s) or by executing risk avoidance plan; the contractor may use it for leveling resources or substituting activities' construction methods to reduce costs. Floats are accepted either just as by-product obtained by critical path method(CPM) scheduling or as asset having significant value. Succinctly, existing studies involved in float value does not consider its' changes on project time domain. It is important to identify float ownership and to quantify its' corresponding values. This paper presents a method that quantifies float value of money that changes over project execution. The method which accurately computes the monetary value of float may contributes to resolve conflicts relative to float ownership and/or delay issues among project participants. It compares the difference between the monetary value of total float - on non-critical path in each and every schedule update. It makes use of critical path method (CPM) and commercial software with which practitioners are already familiar.
