Topology optimization is to find the optimal material distribution of the specified design domain minimizing the objective function while satisfying the design constraints. Since the genetic algorithm (GA) has its advantage of locating global optimum with high probability, it has been applied to the topology optimization. To guarantee the structural connectivity, the concept of compliance pattern is proposed and to improve the convergence rate, small number of population size and variable probability in genetic operators are incorporated into GA. The rank sum weight method is applied to formulate the fitness function consisting of compliance, volume, connectivity and checkerboard pattern. To substantiate the proposed method design examples in the previous works are compared with respect to the number of function evaluation and objective function value. The comparative study shows that the compliance pattern based GA results in the reduction of computational cost to obtain the reasonable structural topology.

Objectives: This study aims to suggest the future direction to improve dental hygienists' competencies to communicate with patients to increase the compliance and dental service satisfaction, based on the analysis of survey data given to patients on dental hygienists' communication patterns with patients. The findings of this research is aimed to serve as the basic data for future researches on related area. Methods: A survey was conducted to ordinary people with experiences of receiving dental treatment in Gwangju and Jeonnam from July 29th 2017 to September 10th 2017. 224 copies of the questionnaire were used for final analysis. Results: The scores of each communication pattern (informative, friendly, and authoritative patterns) of dental hygienists perceived by research subjects were as follows: $3.76{\pm}0.76$, $3.47{\pm}0.62$, and $2.64{\pm}0.70$ respectively. In the effects of communication patterns on the compliance of patients, it was found that the informative communication pattern (${\beta}=0.227$, p=0.008) and friendly communication pattern (${\beta}=0.216$, p=0.012) had positive (+) effects. Conclusions: Thus, the results of this study verified that dental hygienists' communication patterns are important elements affecting patients' compliance and their satisfaction. For the smooth patient-centered bilateral communications, it will be necessary to continuously develop educational programs related to dental hygienists' communication, and also to have continuous researches targeting patient groups for the comparison to meet dental service satisfaction.

Purpose - There is a paucity of literature dealing with exporters' compliance issues in e-commerce exports. This study aims to fill this gap in the literature by exploring customs initiatives to facilitate the e-commerce exports of small and medium-sized enterprises (SMEs) in the changed compliance environment. The central question of this study was divided into five subquestions: first regarding the pros and cons of trade facilitation measures for Korean e-commerce export clearance; second and third questions about risk and compliance management for facilitation fourth about instruments, the changes in Korean SME compliance burden in e-commerce exports, and ways to improve trade facilitation for e-commerce exports. Design/methodology - This study adopts a qualitative approach using a case study method to understand the SME experience in Korean e-commerce export compliance procedures. A qualitative method was selected to answer research questions requiring an in-depth understanding of the regulatory procedures of customs administration and exporters' compliance burden. Because this study addresses the changing compliance environment for which statistical data is insufficient, a quantitative method is considered inappropriate. Based on the approach, data were collected using multiple sources, including an extensive literature review, interviews, and field observations. Thematic pattern matching was applied to interpret the data. Findings - This study examined ways to support SMEs in the changed e-commerce export compliance environment. Facilitation measures for e-commerce exports have contributed to SME access to global markets, simplifying export clearance procedures, and saving exporters' compliance costs. However, such instruments are limited in promoting SME compliance capabilities to cope with intensified competition and strengthened controls over foreign exporters in cross-border e-commerce. Therefore, this study highlights the importance of reshaping facilitation measures for e-commerce exports based on risk and compliance management theories to a system encouraging exporters' voluntary compliance. Originality/value - This study's academic significance derives from verifying the relationship between trade facilitation instruments and risk and compliance management procedures using an actual case in Korea. It is also of practical importance in navigating the directions for improving facilitation measures for e-commerce exports in a changed compliance environment.

To minimize the compliance of frame, a method to optimize the topology of bracing system in a frame is presented. The frame is first filled uniformly with a truss-like continuum, in which there are an infinite number of members. The frame and truss-like continuum are analysed by the finite element method altogether. By optimizing the distribution of members in the truss-like continuum over the whole design domain, the optimal bracing pattern is determined. As a result, the frame's lateral stiffness is enforced. Structural compliance and displacement are decreased greatly with a smaller increase in material volume. Since optimal bracing systems are described by the distribution field of members, rather than by elements, fewer elements are needed to establish the detailed structure. Furthermore, no numerical instability exists. Therefore it has high calculation effectiveness.

In this paper, an auto path generation and an active compliance grinding control using 3-axis farce sensor are presented. These control algorithms enable the grinding robot to follow unknown path of various workpiece shape pattern. The robot is able to go grinding along unknown paths by position controller managing tangential direction angle and cutting speed, with only information about the start position and the end position. Magnitude and direction of normal force are calculated using force data that go through low pass filter. Moreover, normal and tangential directions are separated for force control and velocity control, respectively.

While metabolic syndrome(MS) is rapidly expanding and dietary pattern, the known risk factor of MS, goes through heavy transition to western diet, not many researches have been done on the association between dyslipidemia and dietary factors in Korean adults. The purpose of this study was to investigate the association between compliance with dietary guidelines and dyslipidemia among Koreans. The subjects of 399 adults who visited health examination center were classified into dyslipidemia(n=180) and control(n=219). Diagnosis of dyslipidemia was based on NCEP-ATPIII criteria(triglyceride>=150mg/d, HDL-C<50mg/dl for male, HDL-C<40mg/dl for female). A questionnaire based interview was done to collect information on compliance with dietary guidelines, general characteristics and health related behaviors. Anthropometric variables were measured during the survey. Mean compliance score of dietary guideline was significantly lower in dyslipidemia group than in control. It was associated negatively with waist circumference and positively with serum HDL-cholesterol(p<0.05). Risks of dyslipidemia were significantly decreased in the group with highest dietary guideline score, high serum triglyceride levels(OR=0.484, 95% CI=0.268-0.875), abdominal obesity(OR=0.296, 95% CI=0.159-0.553), and dyslipidemia(OR=0.481, 95% CI=0.266-0.869). These results indicated that increasing compliance with dietary guidelines could be an effective strategy to lower the risk of dyslipidemia among Koreans.

Topical agents including of steroids are easily exposed to Korean patients in community setting. Those topical agents must be use cautiously because can cause adverse drug reaction unlike other oral medication. We evaluate the using pattern topical agents of Korean in community setting. We performed a questionnaire survey in three different pharmacies (general community pharmacy, dermatology clinic oriented pharmacy, general hospital oriented pharmacy) and in three university town. The survey asked necessity of topical agents, the number of applications per day, application period, site, and exist of steroids ingredient, etc. Total 330 people was participated in the survey from May 1st to July 31st, 2014. We analysed the survey by the frequency of each question and cross-analysis of the compliance between general public and pharmacy groups. In results, Korean people used topical agents for sudden skin diseases (66.9%), was gotten by dermatologist's prescription (89.1%), and did not know their diagnosis (39.2%). The people applied topical agents on face (22.3%), less one half FTU (finger tip unit) per application (61.9%), less than one week (62.9%). Though they was received drug education from pharmacist (52.2%), did not heard about adverse effects (78.4%). And compliance of applied times in pharmacy group was higher than in-non-pharmacy group (56% vs 38%, p=0.002). The highest compliance between 3 pharmacy subgroup was general community pharmacy (76.3% vs 61.6%, 61.2%, p=0.039). Compliance of applied duration was no difference between groups. Majority of respondents did not know diversity of ingredients, potency, application area of topical steroids, and replied to feel some vague reluctance and to think so dangerous about topical steroids. In conclusion, Korean people in community use topical agents well but still some exposed to risk from topical agents.
