  • The purpose of this study is to present improvement for classification system of current neighborhood living facility to correspond rapid social change and various industries after understanding its status and problem. In current Building Standard Law, various kinds of buildings are classified for their structure, purpose of use, and building types. The Neighborhood Living Facility is divided into First Neighborhood Living Facility and Second Neighborhood Living Facility with applying area standards, according to facilities of convenience degree for neighborhood inhabitants. This classification, however, has problem in an arbitrary decision and applying of buildings without any definition or standards to adopt. And, there are some mixed neighborhood public functional facilities and amusement business affecting public morals among the Neighborhood Living Facility, so hazard environmental problems are also existed. According to the improved program, the study presents a prompt adoption of new facilities according to various industry increase, with minimum public discontent over adopted area standards. This study suggests making a clear scope through reclassification of Neighborhood Living Facility within the scope of the law on current Neighborhood Living Facility and an improvement plan of introducing necessary definitions on purpose of facility.

  • Recent series of flooding events in urban area has brought a growing concern on storage facilities as a major stormwater management method. The Korean Ministry of Environment has announced diverse plans to tackle the problem, including plans for multi-purpose storages which deal both the stormwater and wastewater. Even though storages can be categorized for different perspectives, classification of possible storages in urban area has not been throughly studied so far. This study investigated diverse references of urban storages and suggested systematic classifications on structural, functional and some other basis. Structural classification mainly concerns structural shape of facilities and includes (1)Cisterns & Rain barrels, (2)Forebays, (3)Dry basins, (4)Wet basins and (5)Constructed wetland. Those functions can be (1)flood prevention (2)water quality control and (3)reuse of stored water. Other criteria that categorize storages depend on (1)height, (2)location, (3)configuration, (4)depth, (5)site of the installation and (6)shape.

  • Interests in ecosystem services have increased and a number of attempts to perform a quantitative valuation on them have been undertaken. To classify the ecosystem types landcover classification maps are generally used. However, some forest types on landcover classification maps have a number of errors. The purpose of this study is to verify the forest types on the landcover map by using a variety of field survey data and to suggest an improved method for forest type classifications. Forest types are compared by overlaying the landcover classification map with the 4th forest type map, and then they are verified by using National Forest Inventory, 3rd National Ecosystem Survey and field survey data. Misclassifications of forest types are found on the forest on the forest type map and farm and other grassland on the landcover map. Some errors of forest types occur at Daegu, Busan and Ulsan metropolitan cities and Gangwon province. The results of accuracy in comprehensive classification show that deciduous forest is 76.1%; coniferous forest is 54.0%; and mixed forest is 22.2%. In order to increase the classification accuracy of forest types a number of remote sensing images during various time periods should be used and the survey period of NFI and the National Forest Inventory and National Ecosystem Survey should be consistent. Also, examining areas with wide forest patch should be prioritized during the field survey in order to decrease any errors.

  • Functional near-infrared spectroscopy-based brain-computer interface (fNIRS-based BCI) has been receiving much attention. However, we are practically constrained to obtain a lot of fNIRS data by inherent hemodynamic delay. For this reason, when employing machine learning techniques, a problem due to the high-dimensional feature vector may be encountered, such as deteriorated classification accuracy. In this study, we employ an elastic net-based feature selection which is one of the embedded methods and demonstrate the utility of which by analyzing the results. Using the fNIRS dataset obtained from 18 participants for classifying brain activation induced by mental arithmetic and idle state, we calculated classification accuracies after performing feature selection while changing the parameter α (weight of lasso vs. ridge regularization). Grand averages of classification accuracy are 80.0 ± 9.4%, 79.3 ± 9.6%, 79.0 ± 9.2%, 79.7 ± 10.1%, 77.6 ± 10.3%, 79.2 ± 8.9%, and 80.0 ± 7.8% for the various values of α = 0.001, 0.005, 0.01, 0.05, 0.1, 0.2, and 0.5, respectively, and are not statistically different from the grand average of classification accuracy estimated with all features (80.1 ± 9.5%). As a result, no difference in classification accuracy is revealed for all considered parameter α values. Especially for α = 0.5, we are able to achieve the statistically same level of classification accuracy with even 16.4% features of the total features. Since elastic net-based feature selection can be easily applied to other cases without complicated initialization and parameter fine-tuning, we can be looking forward to seeing that the elastic-based feature selection can be actively applied to fNIRS data.

  • Purpose: The purpose of this study was to determine correlations between the Berg Balance Scale (BBS), Functional Reach Test (FRT), Timed Up & Go (TUG), Motor-Free Visual Perception Reach Test Vertical format (MVPT-V), Functional Independence Measure (FIM). Methods: The subjects used in this study were 35 stroke patients from Cheongju ST. Mary's hospital. Balance was measured by BBS, FRT. Functional mobility was measured by TUG. Visual perception was measured by MVPT-V. FIM was used to evaluate the activities of daily living. Data was analyzed using pearson product correlation. The TUG and MVPT-V index were analyzed by linear regression. Results: There was a statistically significant difference between FRT and BBS (r=0.89, p<0.01), FIM (r=0.74, p<0.05), MVPT-V (r=0.40, p<0.05), and TUG (r=-0.36, p<0.05). There was significant statistical differences between TUG and MVPT-V (r=-0.64, p<.01). However, statistically significant differences were observed between BBS and FIM (r=0.79, p<0.01). The visual close item of the MVPT-V showed the strongest variance in predicting TUG. Conclusion: The use of both quantitative and qualitive scales was shown to be a good measuring instrument for the classification of general clinical performances of stroke patients. In particular, the results suggest that the visual perception test may be able to predict functional locomotion in stroke patients.

  • A new manual of System of Health Accounts (SHA) 2011, was published jointly by the Organization for Economic Cooperation and Development (OECD), Eurostat, and World Health Organization in 2011. This offers more complete coverage than the previous version, SHA 1.0, within the functional classification in areas such as prevention and a precise approach for tracking financing in the health care sector using the new classification of financing schemes. This paper aims to demonstrate current health expenditure (CHE) and National Health Accounts of the years 1970-2014 constructed according to the SHA2011. Data sources for public financing include budget and settlement documents of the government, various statistics from the National Health Insurance, and others. In the case of private financing, an estimation of total revenue by provider groups is made from the Economic Census data and the household income and expenditure survey, Korean healthcare panel study, etc. are used to allocate those totals into functional classifications. CHE was 105 trillion won in 2014, which accounts for 7.1% of Korea's gross domestic product. It was a big increase of 7.7 trillion won, 7.9%, from the previous year. Public share (government and compulsory schemes) accounting for 56.5% of the CHE in 2014 was still much lower than the OECD average of about 73%. With these estimates, it is possible to compare health expenditures of Korea and other countries better. Awareness and appreciation of the need and gains from applying SHA2011 for the health expenditure classification are expected to increase as OECD health expenditure figures get more frequently quoted among health policy makers.

  • It has problems to use the existing construction information classification system as the bridge breakdown structure due to lack of relationships between element classes. In this study, we proposed the bridge breakdown system for supplementation of above-mentioned classification system. The proposed system, for geometric information modeling, was based on international standards of methodology for structuring part families namely PLIB Part 42. In particular, the breakdown system, considering of the functional classification for the semantic information of the elements is included. In addition, we proposed a basic framework for actual modeling using bridge breakdown system and showed that it can be used in practice.

  • Purpose: The objective of this study was to identify functional problems, including walking ability, of patients with strokes using the International Classification of Functioning, Disability, and Health (ICF) and to present a method that could solve functional problems, thereby determining the applicability of the ICF to increase the quality of evaluation and intervention in clinical fields in the future. Methods: Information on stroke patients who were admitted and treated in a hospital was collected. The authors conducted evaluations, interventions, and measurements of the results of the ICF tool in order to improve gait abilities of patients. The subjects were trained using proprioceptive neuromuscular facilitation (PNF) one hour a day and five times a week for four weeks. The result measurement variables were a six-minute gait test, 10 m velocity test, gait instability test, and measurements using the ICF sheet. Results: In the six-minute gait test, gait distance increased by 48 m, from 102 m to 150 m. The gait velocity test result showed an improvement from 0.36m/s to 0.44m/s. The subjects performed a gait instabilitytestwithacupfilledwith50mmwater. In the gait instability test, the amount of water was 38 mm before the intervention; however, it was 50 mm after the intervention. The gait velocity with a cup filled with water improved from 0.25m/s to 0.31m/s. Conclusion: An evaluation and intervention were designed with the ICF tool for stroke patients. Gait abilities improved when the PNF technique was used. The IFC method can be used for evaluation and intervention, and it could help improve gait abilities of stroke patients.

  • The paper reviews various classifications and surgical techniques for the treatment of temporomandibular joint ankylosis. PubMed, EBSCO, Web of Science, and Google Scholar were searched using a combination of keywords. Articles related to classification, resection-reconstruction of the temporomandibular joint, and management of airway obstruction were considered and categorized based on the objectives. Seventy-nine articles were selected, which included randomized clinical trials, non-randomized controlled cohort studies, and case series. Though several classifications exist, most classifications are centered on the radiographic extent of the ankylotic mass and do not include the clinical and functional parameters. Hence there is a need for a comprehensive staging system that takes into consideration the age of the patient, severity of the disease, clinical, functional, and radiographic findings. Staging the disease will help the clinician to adopt a holistic approach in treating these patients. Interpositional arthroplasty (IA) results in better maximal incisal opening compared with gap arthroplasty, with no significant difference in recurrent rates. Distraction osteogenesis (DO) is emerging as a popular technique for the restoration of symmetry and function as well as for relieving airway obstruction. IA, with a costochondral graft, is recommended in growing patients and may be combined with or preceded by DO in cases of severe airway obstruction. Alloplastic total joint replacement combined with fat grafts and simultaneous osteotomy procedures are gaining popularity. A custom-made total joint prosthesis using CAD/CAM can efficiently overcome the shortcomings of stock prostheses.

  • Hemodialysis (HD) patients face a common problem of malnutrition due to poor appetite. This study aims to verify the appetite alteration model for malnutrition in HD patients through quantitative data and the International Classification of Functioning, Disability, and Health (ICF) framework. This study uses the Mixed Method-Grounded Theory (MMGT) method to explore various factors and processes affecting malnutrition in HD patients, create a suitable treatment model, and validate it systematically by combining qualitative and quantitative data and procedures. The demographics and medical histories of 14 patients were collected. Based on the theory, the research design is based on expansion and confirmation sequence. The usefulness and cut-off points of the creatinine index (CI) guidelines for malnutrition in HD patients were linked to significant categories of GT and the domain of ICF. The retrospective CIs for 3 months revealed patients with 3 different levels of appetite status at nutrition assessment and 2 levels of uremic removal. In the same way, different levels of dry mouth, functional support, self-efficacy, and self-management were analyzed. Poor appetite, degree of dryness, and degree of taste change negatively affected CI, while self-management, uremic removal, functional support, and self-efficacy positively affected CI. This study identified and validated the essential components of appetite alteration in HD patients. These MM-GT methods can guide the selection of outcome measurements and facilitate the perspective of a holistic approach to self-management and intervention.
