  • Students with learning disability have difficulty with attention and academic achievement Music can be an effective tool to enhance level of participation. The purpose of this study is to examine how much can be structured to enhance the attention span and related academic skills needed to achieve educational goals. The study has implemented structured music therapy sessions for three middle school students with learning disability. They participated in 20 sessions which were 30 minutes in length for ten weeks. The implemented music therapy sessions were designed using songs, playing, and listening to music. In order to test their level of attention, Frankfurter Aufmerksamkeits-Inventar(FAIR) Attention Test is implemented and Conners' Comprehensive Teacher's Rating Scale(CTRS-10) are used on the week before and after music activities. Also videotaping is used so as to analyze how correctly they do their task and how the correctness is changed period by period and to evaluate how often for ten minutes they make an eye contact with their teacher. The conclusions of this study are as follows: Firstly, the organized music activities have a positive affection on improving the attention of three middle school students who have learning disabilities. Fair Attention Test shows that they can do their task with more accuracy than in the previous period. Secondly, three students of this study improved their attention and made an eye contact more often than before this study, which is revealed through the analysis of the pre and post test results evaluated by CTRS-10. The results of the study indicate that structured use of music in various level of activities can help students to enhance attention span and the related academic skills.

  • For government and public institutions, civil complaints containing direct requirements of citizens can be utilized as important data in developing policies. However, it is difficult to draw accurate requirements using text mining methods since the nature of the complaint text is unstructured. In this study, a new method is proposed that draws the exact requirements of citizens, improving the previous text mining in analyzing the data of civil complaints. The new text-mining method is based on the principle of Co-Occurrences Structure Map, and it is structured by two-step association analysis, so that it consists of the first-order related word and a second-order related word based on the core subject word. For the analysis, 3,004 cases posted on the electronic bulletin board of Busan City for the year 2016 are used. This study's academic contribution suggests a method deriving the requirements of citizens from the civil affairs data. As a practical contribution, it also enables policy development using civil service data.

  • The spinel structured $LiMn_2O_4$ was prepared from $Li_2CO_3$ and $MnO_2$ by calcination at various temperatures in the range of $750{\sim}900^{\circ}C$. It was found that the most suitable cubic structure of $LiMn_2O_4$ was obtained by heating at $850^{\circ}C$ for 12 hrs. However, in the calcination at $900^{\circ}C$, $Mn^{4+}$ of 0.06M was changed to $Mn^{+3}$ by the oxygen loss, so that it has been shown that the formula has changed to $LiMn_2O_{3.97}$. This phenomena were in agreement with the Jahn-Teller distortion by the increment of $Mn^{+3}$ ion on the octahedral sites of the spinel structured $LiMn_2O_4$. The results showed that after 15 charge/discharge cycles in the voltage range from 3.5V to 4.3V versus Li/$Li^+$ with a current density of $0.25mA/cm^2$, the spinel structured $LiMn_2O_4$ that was prepared at $900^{\circ}C$ showed a lower discharge capacity, 82~50 mAh/g, while the $LiMn_2O_4$, prepared at $850^{\circ}C$, showed the discharge capacity of 102~64 mAh/g.

  • Objectives : In the psychiatry, structured interview is very important tool to be used in epidemiological or psychopharmacological studies. However, investigators often find that the administration of comprehensive diagnostic interviews is time-consuming and expensive to be used in clinical or research settings. Considering these points, Sheehan and his colleagues developed MINI (Mini International Neuropsychiatric Interview) to meet the need for a brief, reliable, and valid structured diagnostic interview for psychiatric disorders. The MINI has been translated into many languages and used in many countries. Therefore, we translated the MINI into Korean and determined its validity in this study. Methods : Twohundred seventy patients and normal subjects participated in the validation of the MINI versus an expert's professional opinion. Schizophrenia and other psychotic disorders, mood disorders including major depressive disorder and bipolar disorder, anxiety disorders including panic and other phobic disorders, and alcohol dependence were included in this study. The validity was obtained by examination whether MINI based diagnoses were compatible with diagnoses by expert psychiatrists. Results : The range of Kappa values was 0.22 (somatoform disorder) to 0.93 (bipolar disorder - past). Overall agreement between MINI and expert's diagnoses were good. The Kappa values for anxiety disorders seemed to be higher than those for other disorders. Conclusion : The MINI Korean version has the good validity. It also has potential applications as a diagnostic tool for psychiatric disorders.

  • The purpose of this study is to investigate whether standardized patient(SP) can be used as a reliable examiner in Objective Structured Clinical Examination(OSCE). 4 SPs and 4 faculties who have more than 2 years experience of OSCE scoring were selected. For 1 assignment 2 members of faculty and 2 SPs were designated as raters. SPs were educated for assessing 2 technical skills, male Foley catheter insertion and wound dressing, for 8 hours (4 hours / day, each topic). The definition, method, cautions and complications for each of procedural skills were covered in the education. Theoretical lectures, video learning, faculty demonstration and practical training on mannequins were employed. The 8 raters were standardized for an hour with simulated OSCE scoring using previous videos on the day before the OSCE. Each assessment was composed of 14 checklists and 1 global rate. The allotted time for each assignment was 5minutes and for evaluation time 2 minutes per student. The evaluation from the faculty and SPs were compared and analyzed with the GENOVA program. The overall generalizability coefficient (G coefficient) was 0.839 from two cases of OASTS. The reliability of the raters was high, 0.946. The inter-rater agreement between faculty group and SP group was 0.949 for checklist and 0.908 for global rating. Therefore SPs can play a role of raters in OSCE for procedural skills, if they are given the appropriate training.

  • This study aimed to investigate the current uses of subheadings that appear in medical science journal abstracts and to discuss its potential implications for medical science from the perspectives of library and information science. To conduct this study, the following nine sub-fields in medical science were selected: cancer, ethics, genetics, infectious disease, neurology, pediatrics, immunology, psychiatry, and cardiology. Random sample data were drawn based on the years 2010 to 2015 from the PubMed database. This study investigated the extent of the uses of subheadings, variants of subheadings, and common formation of subheadings with the help of a frequency analysis. The specific findings of this study are summarized as the following: 1) more traditional abstracts are used across almost all sub-fields of medical science; 2) on average, 4.1 subheadings were used in the sample dataset; and 3) the most frequently used set of subheadings is OBJECTIVES, METHODS, RESULTS, and CONCLUSIONS. This subheading set appears to be the de facto standard across all medical science journals. The analysis of subheadings in structured abstracts and the issues raised in this study can be beneficial for journal editors and other academics in medical science as well as library and information science.

  • 3D-structured (embossed) aluminum sheets have been used in the heat insulation purpose for automative exhaust parts because of increasing their surface areas and stiffness reinforcement imposed in making the embossing pattern. However, there are many restrictions in press forming of the embossed sheet compared with the flat sheet (non-embossed one) because of its difference in the mechanical properties and the geometrical 3-dimensional shape. In this paper we investigated the deformation characteristic of embossed aluminum sheet in the incremental sheet forming process which has frequently used in the design verification and the trial manufacturing of sheet products. The single point incremental forming (SPIF) experiments for the rectangular cone forming using the CNC machine with a chemical wood-machined die and a circular tool shape showed that the formability of the embossed sheet are better than that of the flat sheet in view of the maximum angle of cone forming. This comes from the fact that the embossed sheet between the tool and the elastic die wall is plastically compressed and the flatted area contributes to increase the plastic deformation. Also the tool path along the outward movement from the center showed a better formability than that of the inward movement from the edge. However the surface quality for the tool path along the outward movement evaluated from the surface deflection is inferior than that of the tool path along the inward movement.

  • To recruit nurses with skills, the hospital must evaluate the skills of the applicants. But objective evaluation of the skills is a difficult. Many hospitals are using written examination or oral test only and are not testing the nursing skills directly when they recruit new nurses. OSCE(Objective Structured Clinical Examination) is a method developed for the evaluation of clinical skills objectively. In this study, 16/20 nurse managers of one university-affiliate hospital were assembled for the project of developing 7 OSCE modules by themselves, and then they ran OSCE using those modules for 40 nursing students. They scored nursing skills of the students using checklists they designed. The whole process was proceeded phase by phase using step-wise approach model. The project was successful; inter-personal consistency of the scores were high; nurse managers became confident in objective skill evaluation; subjective responses for this project were favorable. The hospital adopted OSCE in recruitment process thereafter. This experience might be applied to other hospitals who want to recruit nurses with skills.

  • XML data generally consists of a hierarchical tree-structure which is reflected in mechanisms to store and retrieve XML data. Therefore, when storing XML data in the database, the hierarchical relationships among the XML elements are taken into consideration during the restructuring and storing of the XML data. Also, in order to support the search queries from the user, a mechanism is needed to compute the hierarchical relationship between the element structures specified by the query. The structural join operation is one solution to this problem, and is an efficient computation method for hierarchical relationships in an in database based on the node numbering scheme. However, in order to process a tree structured XML query which contains a complex nested hierarchical relationship it still needs to carry out multiple structural joins and results in another problem of having a high query execution cost. Therefore, in this paper we provide a preprocessing mechanism for effectively reducing the cost of multiple nested structural joins by applying the concept of equivalence classes and suggest a query path reduction algorithm to shorten the path query which consists of a regular expression. The mechanism is especially devised to reduce path queries containing branch nodes. The experimental results show that the proposed algorithm can reduce the time requited for processing the path queries to 1/3 of the original execution time.

  • In recent years, nano-structured thin film systems are often applied in industries such as MEMS/NEMS device, optical coating, semiconductor or like this. Thin films are used for many and varied purpose to provide resistance to abrasion, erosion, corrosion, or high temperature oxidation and also to provide special magnetic or dielectric properties. Quite a number of articles to evaluate the characterization of thin film structure such as film density, film grain size, film elastic properties, and film/substrate interface condition were reported. Among them, the evaluation of film adhesive to substrate has been of great interest. In this study, we fabricated the polymeric thin film system with different adhesive conditions to evaluate the adhesive condition of the thin film. The nano-structured thin film system was fabricated by spin coating method. And then V(z) curve technique was applied to evaluate adhesive condition of the interface by measuring the surface acoustic wave(SAW) velocity by scanning acoustic microscope(SAM). Furthermore, a nano-scratch technique was applied to the systems to obtain correlations between the velocity of the SAW propagating within the system including the interface and the shear adhesive force. The results show a good correlation between the SAW velocities measured by acoustic spectroscope and the critical load measured by the nano-scratch test. Consequently, V(z) curve method showed potentials for characterizing the adhesive conditions at the interface by acoustic microscope.
