This study shows that a functional order relationship of national highways in rural areas, which provides the functional system as a principal and minor arterial highways, can be established by the use of statististics. As a result, the adequate functional design criteria of those highways are proposed on the basis of the traffic characteristics in those areas. According to those statistical studies, a function of national highways in the national road network is proved to form three categories broadly. Especially, the survey results based on the traffic characteristics on each road sections show that the initially constructed national highways can not provide an adequate functional role as the arterial highways in the studied areas. In order to operate the intended national highways functionally as the arterial highways, the functional design criteria of highways and the standard order of highway facilities based on the design traffic speed should be considered as an alternative.

We investigated perception and educational demand for health functional foods among nutrition teachers and dietitians working in schools. The subjects were 229 nutrition teachers (57.2%) and dietitians (42.7%) working in Chungbuk elementary, middle and high schools. Approximately 67% of the subjects had experience consuming health functional foods. Most of the subjects did not have experience with the side effects after consuming health functional foods. Subjects who were unaware of the legal specifications, classification, and labeling standards for health functional foods (78-91.2%) were much more common than those who were aware of those issues. Most of the subjects perceived health functional foods as a food (45.0%) or as a product between a food and a medicine (44.5%). The subjects recommended themselves (43.1%) or medical doctors/pharmacists (40.8%) as consultation/education specialists for health functional foods. Approximately 66% of the subjects had experience conducting nutritional consultation/education in their schools, but only 3.2% had experience with health functional foods. Only 17.8% of the subjects had experience receiving education on health functional foods. Most subjects (88.2%) demanded education on health functional foods for themselves. The results suggest that an effective education is needed for nutrition teachers and dietitians working in schools for them to play an active role in educating students and their parents about health functional foods in the near future.

Purpose: Blowout fracture can lead to functional impairments and esthetic deformities such as impairment of ocular movement, diplopia, visual loss and enophthalmos. The object of this study is to present a classification and its analysis according to the computed tomographic scan in blowout fractures. We classified blow out fractures into three types according to the anatomical location of fracture, the size of the bone defect and the degree of periosteal injury by using the computed tomography scan. Each progress and complications were analyzed more than mean 1 year. Methods: Among the 155 cases during 4 years, there were 11 cases of medial orbital wall fracture, 97 cases of inferior orbital wall fracture, 47 cases of combined type. The mean age of patients was 31.2 years, ranged from 8 to 84 years. Results: According to our classification, surgical treatments through the nasoendoscopic approach, the subciliary approach, the transconjunctival approach or their combinations were performed in 116 patients, and conservative treatments were done in 46 patients. Presurgical clinical findings of diplopia, impairment of ocular movement, enophthalmos of more than 2 mm were present in 62 patients. After surgical treatment, clinical findings were remained in 7 patients. Conclusion: We think that our classification according to computed tomographic scan is helpful for the indication and it may decrease the complications such as impairment of ocular movement, diplopia, visual loss and enophthalmos.

Statement of Problem. Commonly used classification systems do not inform for dentists the dimension of the available bone at a potential implant site although regarding a variety of morphologic and pathophysiologic aspects using schematic graphs. However, for the implantologist the availability of bone substance is most important independent whether it concerns the jaw basis or the alveolus. Purpose of Study. The present article refers to a new evaluation form, to analyze the available bone with regard to optional immediate loading site by site. According to a new systematic implant planning concept will be presented in two case reports. Results. The feasibility of the classification for planning and documentation of immediately loaded implants is presented in two case reports. Conclusion. The factor of bone support for immediate functional stability is important in dental implantology. The new systematic implant planning helps to systematically estimate the dimension (ASCIi classification) of the alveolus site by site to evaluate the possibility of immediate loading. The Gottingen classification thus aids to determine the degree of stability that can be expected for the planned solution.

Recently, public organizations have been improving the classification in order to introduce records management reference table in accordance with the act on the management of public archives. However, there is no system to mount the revised records management reference table, and there is a problem in usability. The purpose of this study is to design a system function to manage the classification which is the foundation of records management for public organizations. In order to design the function, interviews with the records management specialists of the five public organizations were conducted. Based on this, we have designed a multi-classification system registration function, a hierarchical structure setting function of records, and a record management standard management function.

This study examined whether the difference in the middle cerebral artery (MCA) velocities can predict the prognosis of stroke and whether the prognostic impact differs among stroke subtypes. Transient ischemic attack (TIA) or acute ischemic stroke patients, who underwent a routine evaluation and transcranial Doppler (TCD), were included in this study. The MCA asymmetry index was calculated using the relative percentage difference in the mean flow velocity (MFV) between the left and right MCA: (|RMCA MFV-LMCA MFV|/mean MCA MFV)${\times}100$. The stroke subtypes were determined using the TOAST classification. Poor functional outcomes were defined as a mRS score ${\geq}3$ at 3 months after the onset of stroke. A total of 988 patients were included, of whom 157 (15.9%) had a poor functional outcome. Multivariable analysis showed that only the MCA asymmetry index was independently associated with a poor functional outcome. ROC curve analysis showed that adding the MCA asymmetry index to the prediction model improved the discrimination of a poor functional outcome from acute ischemic stroke (from 88.6% [95% CI, 85.2~91.9] to 89.2% [95% CI, 85.9~92.5]). The MCA asymmetry index has an independent prognostic value for predicting a poor short-term functional outcome after an acute cerebral infarction. Therefore, TCD may be useful for predicting a poor functional outcome in patients with acute ischemic stroke.

The Electroencephalogram (EEG) and evoked potential (EP) t;ave widely been used for study of brain functions. The EEG and EP signals acquired from multi-channel electrodes placed on the head surface are often interfered by other relatively large physiological signals such as electromyogram (EMG) or electroculogram (EOG). Since these artifact-affected EEG signals degrade EEG mapping, the removal of the artifact-affected EEGs is one of the key elements in neuro-functional mapping. Conventionally this task has been carried out by human experts spending lots of examination time. In this paper a neural-network based classification is proposed to replace or to reduce human expert's efforts and time. From experiments, the neural-network based classification performs as good as human experts : variation of decisions between the neural network and human expert appears even smaller than that between human experts.

RNA sequencing (RNA-Seq) is a technology that facilitates transcriptome analysis using next-generation sequencing (NSG) tools. Information on the quantity and sequences of RNA is vital to relate our genomes to functional protein expression. RNA-Seq data are characterized as being high-dimensional in that the number of variables (i.e., transcripts) far exceeds the number of observations (e.g., experiments). Given the wide range of dimensionality reduction techniques, it is not clear which is best for RNA-Seq data analysis. In this paper, we study the effect of three dimensionality reduction techniques to improve the classification of the RNA-Seq dataset. In particular, we use PCA, SVD, and SOM to obtain a reduced feature space. We built nine classification models for a cancer dataset and compared their performance. Our experimental results indicate that better classification performance is obtained with PCA and SOM. Overall, the combinations PCA+KNN, SOM+RF, and SOM+KNN produce preferred results.
