This study aims to investigate the Healthy Family Support Centers'(HFSCs) operational patterns and their programs by surveying 46 HFSC employees in order to prepare for the massive increase of the number of HFSCs nationwide. This study might contribute to not only rebuilding the HFSCs' operational strategies but suggesting visible ideas for the HFSCs' programs. Results were as followed: First, most HFSCs consisted of several teams, i.e., educational team, counseling team and cultural team. However, the number of employees in each team was different from one regional community to another. The most difficult task in the HFSCs' operation was publicity work. Citing the issue of system delivery difficulties, HFSC employees insisted that budgetary deficit was the most difficult obstacle in running the HFSCs. Second was in regards to the programs that each team was planning, performing, and evaluating for each program. The HFSCs' programs were mostly structured around family difficulties or problems that arise according to the family life cycle. Based on these study results, more unified and specialized programs for HFSCs should be developed. In order to achieve this related studies should continue to conducted.

Purpose: The objective of this study was to compare the outcomes of surgical mini-implant placement when potential mini-implant sites were scanned using a lower-dose $180^{\circ}$ acquisition protocol versus a conventional $360^{\circ}$ acquisition protocol. Materials and Methods: Ten dentate human skulls were used to provide sites for potential mini-implant placement. The sites were randomly divided into 2 groups: $360^{\circ}$ and $180^{\circ}$ cone-beam computed tomography (CBCT) acquisition protocols. A small-volume $180^{\circ}$ CBCT scan and a $360^{\circ}$ CBCT scan of each site were acquired using a Morita Accuitomo-170 CBCT machine and then a mini-implant was placed. A follow-up $360^{\circ}$ CBCT scan was done as a gold standard to evaluate the location of the mini-implant and root perforation. Two raters evaluated the scans. Results: Ninety-eight percent of the mini-implants placed did not perforate any root structure. Two percent of the sites had an appearance suggestive of perforation. On a Likert scale, both raters agreed that their subjective evaluation of the diagnostic quality of the protocols, ability to make and read measurements of the sites, and preferences for the specified diagnostic task were comparable. The Cohen kappa showed high inter-rater and intrarater agreement. Conclusion: In this ex vivo study, we found that the $180^{\circ}$ rotational acquisition was as effective as the conventional $360^{\circ}$ rotational acquisition for the preoperative evaluation of potential mini-implant sites.

The leaves and roots of Ligularia stenocephala, which are widely used as a food in Korea, were investigated for their antioxidant activities and cytotoxicity in vitro, and their hepatoprotective effect, alcohol detoxicant efficacy, and memory-enhancing property were investigated in vivo. The unique odor of the leaves was analyzed by GC-MS. Lipid peroxidation, superoxide anion formation, and DPPH radicals were inhibited remarkably by the extracts of the leaves and roots. The leaves of this edible plant significantly protected the hepatotoxicity induced by carbon tetrachloride and further diminished the blood alcohol content in mice. While the roots of this plant exhibited adequate cytotoxicity against four human tumor cell lines, especially against melanoma, the leaves revealed relatively weak activity. Both the leaves and the roots exerted an excellent ameliorating property on scopolamine-induced memory impairment in the passive avoidance task using an animal model. The hexane fraction of the leaves was analyzed by GC-MS, suggesting that a series of terpenoids may be odorous compounds in this plant.

In this paper, we propose a methodology for estimating the optimal traversable destination from the location-based information of the object recognized by the mobile robot to perform the object delivery service. The location estimation process is to apply the generalized Voronoi graph to the grid map to create an initial topology map composed of nodes and links, recognize objects and extract location data using RGB-D sensors, and collect the shape and distance information of obstacles. Then, by applying the hybrid approach that combines the center of gravity and thinning method, the optimal moving position for the service robot to perform the task of grabbing is estimated. And then, the optimal node information for the robot's work destination is updated by comparing the geometric distance between the estimated position and the existing node according to the node update rule.

Pulmonary hypertension (PH) is a condition of increased blood pressure in the pulmonary arteries and is diagnosed with an increased a mean pulmonary artery pressure ≥25 mm Hg. This condition may be associated with multiple clinical situations. Based on pathophysiological mechanisms, clinical presentation, hemodynamic profiles, and treatment strategies, the patients were classified into five clinical groups. Although there have been major advances in the management of PH, it is still associated with significant morbidity and mortality. The diagnosis and treatment of PH have been performed mainly by following European guidelines, even in Korea because the country lacks localized PH guidelines. European treatment guidelines do not reflect the actual status of Korea. Therefore, the European diagnosis and treatment of PH have not been tailored well to suit the needs of Korean patients with PH. To address this issue, we developed this guideline to facilitate the diagnosis and treatment of PH appropriately in Korea, a country where the consensus for the diagnosis and treatment of PH remains insufficient. This is the first edition of the guidelines for the diagnosis and treatment of PH in Korea, and it is primarily based on the '2015 ESC/ERS Guidelines for the diagnosis and treatment of pulmonary hypertension.' with the acceptance and adaptation of recent publications of PH.

As the Korean construction market in the apartment housing has changed to a housing consumer focused market, interest and importance on efficient use and management on existing buildings has increased rather than demand for new buildings. Interest of housing consumers on apartment house quality has increased in this market paradigm, and this spontaneously is connected to quality flaw related defect disputes and lawsuits that the importance of defect diagnosis has continuously increased. This defect diagnosis is directly connected to maintenance charges in defect dispute and lawsuit processes that rather objective and highly credible progress of duty is required. However, most defect diagnosis firms today that progress defect diagnosis are using different diagnosis methods and depend on the experience of experienced professionals that there is no standardized defect diagnosis process. Therefore, the purpose of this study is to provide common defect diagnosis process model for defect diagnosis firms utilizing the BPMN (Business Process Modeling Notation) modeling method. It is expected that this will contribute to professional and reliable task performances of concerned defect diagnosis workers. Furthermore, it is expected that design lawsuit damage will be substantially reduced by standardizing defect diagnosis processes.

The current study was conducted to examine the temporal and spatial activation sequences related to morphosyntactic, semantic and orthographic-lexical sentences, focusing on the morphological-orthographic and lexical-semantic deviation processes in Korean language processing. The Event-related Potentials (ERPs) of 15 healthy students were adopted to explore the processing of head-final critical words in a sentential plausibility task. Specifically, it was examined whether the ERP-pattern to orthographic-lexical violation might show linear precedence over other processes, or the presence of additivity across combined processing components. For the morphosyntactic violation, fronto-central LAN followed by P600 was found, while semantic violation elicited N400, as expected. Activation of P600 was distributed in the left frontal and central sites, while N400 appeared even in frontal sites other than the centro-parietal areas. Most importantly, the orthographic-lexical violation process revealed by earlier N2 with fronto-central activity was shown to be complexes of morphological and semantic functions from the same critical word. The present study suggests that there is a linear precedence over the morphological deviation and its lexical semantic processing based on the immediate possibility of lexical information, followed by sentential semantics. Finally, late syntactic integration processes were completed, showing different topographic activation in order of importance of ongoing sentential information.

CE RCD (Recreational Craft Directive) is a certification for the design and construction of small vessels, including pleasure yachts, which are widely used not only in the countries within the European Union, but also in Japan and Southeast Asia. Recently, South Korean leisure craft shipyards have developed interest in exporting to foreign leisure craft markets such as Europe; however, they have encountered difficulties because of the CE RCD regulations, which are relatively complex and difficult to understand. The requirements for buoyancy and stability, which are essential properties that must be understood within the early stage of ship design, are defined based on ISO 12217. However, preparing this assessment according to ship classification regulations is an exceedingly complex task, even with knowledge of naval architecture. In this research, we have developed design support tools to systematically support assessments and preemptively define design information so that buoyancy and stability assessments based on ISO 12217 can be systematically prepared. Our research results were applied to actual examples of yacht design to confirm validity. We believe that the improved yacht design process presented in this research can act as a foundational reference for enhancing the effectiveness and systematic buoyancy and stability assessments.
