Purpose: This study aimed to identify the current status and correlations among scuba divers' knowledge of safety, compliance with safety rules, and ability to cope with emergency situations. Methods: There were 317 study subjects. Data were collected between September 21, 2012 and September 7, 2013, and analyzed using SPSS software version 21.0. Results: Of the participants, 89.3% wanted to be educated in emergency care, while 69.4% indicated that preparedness in emergency situations for divers is insufficient. 78.5% suggested a need to creat a legal standard for the prevention of accidents. The average scores among the participants showed 3.22 points for knowledge of safety, 3.09 points for compliance with safety rules, and 2.91 points for ability to cope with accidents and emergency situations, with strong correlation among them. The lower license level they had, the lower score they indicated. Conclusion: We suggest there is a need to strengthen systematic educations on knowledge of safety, compliance with safety rules, and the ability to cope with emergency situations and emergency care at the open water level. In addition, there is a need to creat legal standards to consolidate the effects of these changes.

Hearing impaired persons are exposed to the danger since they can't be aware of many dangerous situations like fire alarms, car hones and so on. Therefore they need haptic or visual informations when they meet dangerous situations. In this paper, we design a dangerous sound detection engine for hearing impaired. We consider four dangerous indoor situations such as a boiled sound of kettle, a fire alarm, a door bell and a phone ringing. For outdoor, two dangerous situations such as a car horn and a siren of emergency vehicle are considered. For a test, 6 data sets are collected from those six situations. we extract LPC, LPCC and MFCC as feature vectors from the collected data and compare the vectors for feasibility. Finally we design a matching engine using an artificial neural network and perform classification tests. We perform classification tests for 3 times considering the use outdoors and indoors. The test result shows the feasibility for the dangerous sound detection.

A primitive conceptualization is defined as the set of all intended situations. A non-primitive conceptualization is defined as the set of all the pairs every of which consists of an intended knowledge system and the set of all the situations admitted by the knowledge system. The reality of a domain is considered as the set of all the situation which have ever taken place in the past, are taking place now and will take place in the future. A conceptualization is defined as precise if the set of intended situations is equal to the domain reality. The representation of various elements of a domain ontology in a model of the ontology is considered. These elements are terms for situation description and situations themselves, terms for knowledge description and knowledge systems themselves, mathematical terms and constructions, auxiliary terms and ontological agreements. It has been shown that any ontology representing a conceptualization has to be non-primitive if either (1) a conceptualization contains intended situations of different structures, or (2) a conceptualization contains concepts designated by terms for knowledge description, or (3) a conceptualization contains concept classes and determines properties of the concepts belonging to these classes, but the concepts themselves are introduced by domain knowledge, or (4) some restrictions on meanings of terms for situation description in a conceptualization depend on the meaning of terms for knowledge description.

We examined the relations between the score of the divergent thinking in mathematical (Mathematical Creative Problem Solving Ability Test; MCPSAT: Lee etc. 2003) and non-mathematical situations (Torrance Test of Creative Thinking Figural A; TTCT: adapted for Korea by Kim, 1999). Subjects in this study were 213 eighth grade students(129 males and 84 females). In the analysis of data, frequencies, percentiles, t-test and correlation analysis were used. The results of the study are summarized as follows; First, mathematically gifted students showed statistically significantly higher scores on the score of the divergent thinking in mathematical and non-mathematical situations than regular students. Second, female showed statistically significantly higher scores on the score of the divergent thinking in mathematical and non-mathematical situations than males. Third, there was statistically significant relationship between the score of the divergent thinking in mathematical and non-mathematical situations for middle students was r=.41 (p<.05) and regular students was r=.27 (p<.05). A test of statistical significance was conducted to test hypothesis. Fourth, the correlation between the score of the divergent thinking in mathematical and non-mathematical situations for mathematically gifted students was r=.11. There was no statistically significant relationship between the score of the divergent thinking in mathematical and non-mathematical situations for mathematically gifted students. These results reveal little correlation between the scores of the divergent thinking in mathematical and non-mathematical situations in both mathematically gifted students. Also but for the group of students of relatively mathematically gifted students it was found that the correlations between divergent thinking in mathematical and non-mathematical situations was near zero. This suggests that divergent thinking ability in mathematical situations may be a specific ability and not just a combination of divergent thinking ability in non-mathematical situations. But the limitations of this study as following: The sample size in this study was too few to generalize that there was a relation between the divergent thinking of mathematically gifted students in mathematical situation and non-mathematical situation.

We analyze number agreement in English in the version of Situation Semantics I put forth in [1]. We propose two theoretical notions, agreement target situations and relevance of situations. We propose that structural constraints shift the former in a way governed by the latter. Our analysis shows that number agreement reflects our knowledge about the structure of the world and the speaker's interests in the discourse.

This paper deals with the ways how the AUV can detect and treat possible emergency situations during the mission. The emergency situations can be divided into two parts according to the zones where the situations take place-inner zone, and outer zone. This paper explains how each element of emergency situation is detected and treated, and as a result, introduce the algorithm of this procedure for the autonomous cruising.

The mathematics instructional beliefs of a teacher include the exterior mathematics instructional beliefs and the internal mathematics instructional beliefs. These two kinds of beliefs are formed in two kinds of different situations. The situated theory thinks that beliefs are related with the situations; so, the two kinds of beliefs are showed in the different situations. The internal instructional mathematics beliefs effect on the actual mathematics instruction, they ought to be noticeable.

This study examined children's happy situations and their self-judgment of happiness level. Subjects were 831 children (7-13 years of age). Research findings were that : (1) There were three categories of happy situations : rewards, daily routine activities, non-daily activities/incidents. These categories were subcategorized into personal and relational experiences. Personal experiences gave them greater happiness than relational experiences. (2) The younger children felt happier through relational experiences than older children. (3) Sixty-two percent of the children reported they were happy most of the time. (4) Preschool children answered "I'm happy" more than older children. Sixth grade children answered "I'm happy" least among the entire sample. (5) Academics correlated positively with children's judgment of happiness level; free time correlated negatively with happiness.

This study investigated 4- and 5-year-olds' social knowledge and interpersonal problem solving strategies according to their sex, age, and hypothetical situation, and the relationships among them. Subjects were 116 preschoolers (73 boys and 43 girls; 68 four and 48 five-year-olds). Results showed that preschoolers had the higher scores of freindliness in potential entry situations than in support situations. Also, 4-year-old children were higher in forceful problem solving strategies than 5-year-olds. Furthermore, children's social knowledge assertiveness scores were positively related to their relevant problem solving strategies in conflict situations, while children's social knowledge friendliness scores were negatively related to their forceful problem solving strategies in conflict and potential entry situations.

The purpose of this study were to investigate the conceptual framework of situational vari-ables, and to find out the causal relationships of apparel buying behavior on usage situations and consumer characteristics. Data were collected viaa questionnaire developed on the previous studies from 386 housewives living at Seoul and Pusan, and analyzed by T-test, Factor analysis, and Path analysis. Results indicated that there were significant differences of apparel buying intention on the types of apparel usage situations. The communi-cation situation was found to be composed of Printed Information and Interpersonal Infor-mation, and the buying situation to be composed of Consumer Conditions, such as weather or mood, Shopping Company, Store Atomosphere, Display, and Store Service. The product char-acteristics considered by consumers in apparel buying process were composed of Practically, Fashionability, Brand, and Approval of others. The causal relationships of apparel buying behavior were significantly different on the types of usage situations and the degree of clothing in-volvement.
