  • Submerged floating tunnel (SFT) is a type of tunnel which causes the tunnel segments to float in the water. When the SFTs are connected to the ground, the connection between the SFT and the subsea bored tunnel is fragile due to the difference in behavioral characteristics between the two types of tunnels. Therefore, special design and construction methods are needed to ensure the stability of the area around the connection. However, since previous research on the stability of the connection site has not been undertaken enough, the basic step necessitates the evaluation of ground behavior at the shore connection. In this study, the numerical analysis targeting the shore connection between the subsea bored tunnel and the SFT was simulated. The strain concentration at the shore connection was analyzed by numerical simulation and the effects of several factors were examined. The results showed the instability in the ground close to the shore connection due to the imbalance in the behavior of the two types of tunnels; the location of the strain concentration varies with different environmental and structural conditions. It is expected that the results from this study can be utilized in future studies to determine weak points in the shore connection between the submerged floating tunnel and the subsea bored tunnel, and devise methods to mitigate the risks.

  • The purpose of this study was to characterize the putative anxiolytic-like effects of the 70% ethanol extract of Portulaca oleracea (EPO) using an elevated plus maze (EPM) in mice. The EPO was orally administered at 50, 100, 200 or 400 mg/kg to ICR mice, 1 h before the behavioral evaluation in the EPM, respectively. Control mice were treated with an equal volume of 10% tween 80, and positive control mice with diazepam (1 mg/kg). Single treatments of the EPO significantly increased the percentage of time spent and arm entries into the open arms of the EPM versus controls (P < 0.05). Moreover, there were no changes in the locomotor activity and myorelaxant effects in any group compared with the saline controls. In addition, the anxiolytic-like effects of the EPO were blocked by flumazenil (10 mg/kg, i.p), a $GABA_A$ antagonist not by WAY 100635 (0.3 mg/kg, i.p), a 5-$HT_{1A}$ receptor antagonist. These results indicate that P. oleracea is an effective anxiolytic agent, and suggest that the anxiolytic-like effects of P. oleracea is mediated via the GABAergic nervous system.

  • Objectives : This study explored the clinical differences in attention-deficit hyperactivity disorder (ADHD) patients with and without developmental coordination disorder (DCD). Methods : Participants were 49 children and adolescents with ages between 6 and 18 years. These subjects were placed into 2 groups: ADHD without DCD (24) and ADHD with DCD (25). We used several evaluation tools on both groups: the Affective Disorders and Schizophrenia-Present and Lifetime Version- Korean Version (K-SADS-PL), Wechsler Intelligence Scale for Children-III (WISC-IIII), Child Behavior Check List (CBCL), Korean Personality Rating Scale for Children (K-PRC), and Bruininks-Osretsky Test of Motor (BOT-2). Results : Patients with both ADHD and DCD had a lower performance intelligence quotient and more internal and external behavioral symptoms than patients with ADHD but not DCD. It is possible that patients with ADHD and motor coordination problems should be noticed earlier and given intensive treatment.

  • Background: Alcohol and tobacco use are two major behavioral risk factors implicated in increased morbidity and mortality. Since both substances are widely used in Korea, a concerted effort is currently underway to reduce the use of tobacco and alcohol in Korea. Objectives: Efforts directed toward preparing health promotion planners and health educators from local health departments to organize and implement community-wide interventions to reduce the proportion of people smoking and reduce the average level of alcohol consumption in the community. Methods: Comprehensive multi-media health promotion materials were developed based on health behavior theories and strategies. The materials were developed to introduce a user-oriented developmental approach by making messages more persuasive and organizing content in a user-friendly manner. Health educators from all local health departments in the country were trained in the use of the materials, to enable them to develop community interventions to reduce smoking and drinking. Implications for Practitioners: The process followed in developing the health intervention materials is described in detail to assist practitioners who need to develop effective programs to reduce the use of tobacco and alcohol. Sections of the report explain health intervention theories, specific program activities to include in an intervention, development, organization, evaluation, choosing a target audience, choosing goals of an intervention, and methods of making program content vivid and persuasive.

  • Recently combining regimen of minimal doses of chloral hydrate, hydroxyzine and midazolam is good in sedation of children. Midazoalm, water soluble benzdiazepine, has rapid onset and relatively short duration of action. And midazolam has prospective amnesic effect. With these advantages midazolam is popular in conscious sedation for children. This study was to reveal the dose-dependency of behavior and physiologic effects of sublingual midazolam. Sedation records were surveyed retrospectively, of which the patients admitted from April, 2005 to July, 2007. we assigned three groups according the dose of midazolam, 0.1 mg/kg, 0.2 mg/kg and 0.3 mg/kg, respectively and the behavioral evaluation was analyzed with Houpt scale statistically. Combined sublingual midazolam increased the success rate in sedation and the vital signs were stable during sedation.

  • Personalized product recommendation service is receiving attention as a new marketing strategy while supporting consumer information search and purchasing decisions. This study attempted to verify the effect of self-reference on service use behavior through the dual path of cognitive attitude and emotional attachment. Using convenience sampling, an online survey was conducted with 324 women who were in their 20s and 30s. After collecting and compiling the survey data, the reliability and validity of variables constituting the conceptual research model were verified through confirmatory factor analysis using AMOS 22.0. Next, the significance of sequentially mediated pathways was verified using Process 3.5 Model 80. The results showed that self-referencing not only significantly affects service use intention by simply mediating cognitive attitudes but also sequentially mediates cognitive attitudes and additional information search. Furthermore, self-referencing was significant as an indirect path to service use intention by mediating additional information search. However, in the path mediated by emotional attachment, self-referencing was considered as a simple mediated path leading to service usage intention. These results indicate a dual path in the psychological mechanism, through cognitive and emotional evaluation, that prompts consumer behavioral responses to the personalized product information provided in the shopping process.

  • The incidence of vivax malaria in Korea was reduced to a low plateau. For successful elimination of vivax malaria, socio-behavioral changes in the communities are essential. This study aimed to figure out awareness of the inhabitants on the vivax malaria endemicity. The 407 participants including vivax malaria patients and uninfected inhabitants in Gimpo- and Paju-si, Gyeonggi-do, known as high-risk areas in Korea. We used a community-based study design and non-probability sampling method using primary data. Except for the perception about the public health facilities' capability to cope with anti-malaria programs, the 2 groups of participants shared the same level of awareness about public promotional and educational measures and opinions for malaria elimination from the community. Thus, our future goals for malaria prevention and elimination are to develop more active and well-organized community-based education and evaluation programs collaborating with the community healthcare authorities and local governments.

  • Purpose: This study was conducted to review the curriculum and license examination of physical therapists in the United States. Methods: The doctor of physical therapy (DPT) curriculum was evaluated by a review Course Work Tool version 6 (CWT6) data and current physical therapy licensure examination (National Physical Therapy Exam, NPTE) category in the United States. Results: The results indicated that they were required to meet the doctor of physical therapist degree based on 'Guide to Physical Therapist Practice' of American Physical Therapy Association (APTA). This includes general education in the areas of communications and humanities, physical science, biological science, social and behavioral science, and mathematics. A minimum of one course must be completed successfully in each area of general education. Moreover, there should be at least 68 didactic credits of professional education and 22 clinical education credits, which is a minimum of two full-time clinical internships with no less than 1050 hours in total, which were supervised by a physical therapist. Regarding the physical therapy licensure examination, National Physical Therapy Exam (NPTE, 2016) consisted of a physical therapy examination (26.5%), evaluation, differential diagnosis, baseline of prognosis (32.5%), intervention (28.5%), protection, responsibility, and research (6.5%) based on the 'Guide to Physical Therapist Practice'. Conclusion: Based on the study results provided above, it is considered a standard to meet domestic reality as the Guide to Physical Therapist Practice of APTA for South Korean physical therapists.

  • Utilization of fiber beam-column element has gained considerable attention in recent years due mainly to its ability to model distributed plasticity over the length of the element through a number of integration points. However, the relatively high sensitivity of the method to modeling parameters as well as material behavior models can pose a significant challenge. Residual drift is one of the seismic demands which is highly sensitive to modeling parameters and material behavior models. Permanent deformations play a prominent role in the post-earthquake evaluation of serviceability of bridges affected by a near-fault ground shaking. In this research, the influence of distributed plasticity modeling parameters using both force-based and displacement-based fiber elements in the prediction of internal forces obtained from the nonlinear static analysis is studied. Having chosen suitable type and size of elements and number of integration points, the authors take the next step by investigating the influence of material behavioral model employed for the prediction of permanent deformations in the nonlinear dynamic analysis. The result shows that the choice of element type and size, number of integration points, modification of cyclic concrete behavior model and reloading strain of concrete significantly influence the fidelity of fiber element method for the prediction of permanent deformations.
