  • The purpose of this paper was analyzing the contents of life science area in elementary science textbooks according to Korean science curricula change to get suggestions for the advancement of science curriculum. The framework of content analysis was developed by revising TIMSS 2015 life science evaluation framework. The results of this research were as follows: 'The differences of living things and non-living things appearing in the first grade mostly were not included in the 1st, the 6th and the 2009 revised curricula. Contents emphasizing rural life were appeared from 'Teaching themes period' to the 2nd curriculum period, disappeared from the 3rd curriculum period until the 2009 revised curriculum. Contagious disease was emphasized in all elementary grades in the 1st curriculum period, which reflected a social phenomena emphasizing health and hygiene after the Korean War. Mostly fungus was included until the 7th curriculum period and bacteria and virus were added from the 2007 revised curriculum period. The way of improving health was emphasized continuously.' The differences of living things and non-living things should be included in elementary science curriculum for the correct 'life' concept formation of elementary students. 'Strategies for helping the living of descendants' and 'the heredity of animal and plant' which were appeared in the lower grades, should be included at the higher grades with greater depth. The incoming elementary science textbooks also need to include science contents about evolution in greater depth, along with human health.

  • The purpose of this study was to analyze paper and pencil test items of life science I in high school to diagnose problems of the test items developed by teachers, and to provide some implication for better assessment. 690 selection-type items and 162 supply-type items in life science I were collected from 10 general high schools. In the analysis of test items, the ratio of the selection-type item and the supply-type item was 81:19 in the number of items based on item type, while the ratio was 74.4:25.6 in the distribution of marks, indicating that the distribution of marks compared to the number of items was higher in the supply-type items. In the analysis by the Bloom's revised taxonomy of educational objectives, the items of 'conceptual knowledge' in the knowledge and those of 'understanding' in the cognition process were shown most in both the selection-type item and the supply-type item. In the analysis by the science assessment frameworks of NAEA, the items of 'knowledge' were shown 9 times more than those of 'inquiry'. When compared to the level of difficulty presented in the two-way specification table and the percentage of correct answers in the selection-type item, the concurrence was 41.5%. When compared to the ratio of number of items based on the item type of the supply-type items, the short-answer items were 34.0%, the descriptive items were 61.1%, and the drawing items were 4.9%. The drawing items were mainly developed in the unit of 'Cells and Continuity of Life'. When the descriptive items were classified by the acceptance of response, all the items were 'response restricted' type, and the items of 'restricted in content range' type among them were highest. When the items were classified by presentation of data, the items of 'presentation of data' type were highest(65.4%), and when classified by type of question, the items of 'knowledge description' type were highest(80.4%). In conclusion, it is needed to develop items belonging to 'inquiry' area more in the school, and to increase the ratio of the descriptive items, presenting various types of items.

  • The purpose of this study is to analyze the determinants of insurance product cross selling performance. For the study, 11 insurance managers and 2 sales managers belonging to A insurance agency were selected and in-depth interviews were conducted. The analysis of the research data was done by the open coding method suggested by Strauss & Corbin(2001). As a result, 84 concepts, 28 subcategories and 10 categories were derived. The ten categories that were determinants of insurance product cross-selling performance were personal characteristics, consultation method, cross-selling ratio, sales culture, education, customer change, customer DB provision, satisfaction, business support system, and customer service. In order to verify the qualitative results, quantitative analysis was emplyed to the actual performance data of insurance planners belonging to A insurance agency during April 2016~March 2019. As a result of the analysis, the age, position, and the number of months worked in the insurance company had a statistically significant effect on the number of life insurance contracts in total insurance contracts and life insurance contracts in total insurance contracts. In addition, the age, position, and the number of months worked in the insurance company had a statistically significant negative impact on the number of non-life insurance contracts in the total number of insurance contracts and the total amount of insurance contracts in total insurance contracts. The result of this study can be an important basic data for the development of educational programs and job support systems for the training of insurance planners. Insurance companies should refer to ten categories derived from qualitative research in order to increase the performance of insurance planners and to promote long-term service. Especially, it is necessary to develop specialized education programs and job support systems so that cross sales that increase the proportion of life insurance sales increase.

  • This study aims to examine genetics problem-solving processes of high school students with different learning approaches. Two second graders in high school participated in a task that required solving the complicated pedigree problem. The participants had similar academic achievements in life science but one had a deep learning approach while the other had a surface learning approach. In order to analyze in depth the students' problem-solving processes, each student's problem-solving process was video-recorded, and each student conducted a think-aloud interview after solving the problem. Although students showed similar errors at the first trial in solving the problem, they showed different problem-solving process at the last trial. Student A who had a deep learning approach voluntarily solved the problem three times and demonstrated correct conceptual framing to the three constraints using rule-based reasoning in the last trial. Student A monitored the consistency between the data and her own pedigree, and reflected the problem-solving process in the check phase of the last trial in solving the problem. Student A's problem-solving process in the third trial resembled a successful problem-solving algorithm. However, student B who had a surface learning approach, involuntarily repeated solving the problem twice, and focused and used only part of the data due to her goal-oriented attitude to solve the problem in seeking for answers. Student B showed incorrect conceptual framing by memory-bank or arbitrary reasoning, and maintained her incorrect conceptual framing to the constraints in two problem-solving processes. These findings can help in understanding the problem-solving processes of students who have different learning approaches, allowing teachers to better support students with difficulties in accessing genetics problems.

  • This study aims to look into the concept of Human Mind and Moral Mind and the issue of their axiological interpretation in Daesoon Thought. In the Song dynasty, the concept of the Human Mind and Moral Mind was understood as indicating two aspects of the universal Human Mind. Discourse on this theory was undertaken by scholars such as Cheng Yichuan (程伊川), Su Shi (蘇軾), and Zhu Xi (朱熹). The differences between the Human Mind and Moral Mind were interpreted as issues of cultivation. The discussion of the Human Mind and Moral Mind were established through a systematic theory by Zhu Xi, and this developed into various forms of discourse and ideological stances thereafter. One of the most important issues of the Human Mind and Moral Mind theory was its axiological interpretation, which was divided largely into three patterns. One was to interpret the Human Mind and Moral Mind as evil and good respectively (proponents included Cheng Yichuan and Zhu Xi in his early theories), the other one saw them as value-neutral and good (proponents included Zhu Xi, Toegye 退溪, and Yulgok 栗谷), and the last one interpretation held them as pre-evil and pre-good (Dasan 茶山). As the Human Mind and Moral Mind can be seen as a universal human issue, the examination of those patterns in the Confucian tradition would be meaningful for understanding the Human Mind and Moral Mind as a theoretical base in Daesoon Thought. In Daesoon Thought, the Human Mind and Moral Mind are defined as private and public respectively, but no further explanation is provided regarding these items. If we infer by considering the two in the light of the overall ideology and values that Daesoon Jinrihoe pursues, the Human Mind can be said to represent basic biological desires such as clothing, food, and sexual satisfaction all of which are human vital activities needed for the preservation of the human race. The Moral Mind can be seen as a mind that is set upon practicing morality and realizing the ideological aims of 'supporting the nation and comforting the people,' 'vast saving all creatures,' and achieving 'harmony and peace for humankind.' However, the conscience and the selfish mind, which are related axiologically to the Human Mind and the Moral Mind, are defined respectively as good and evil and explained in a relatively systematic way which includes conceptual claims and details on the origin of these aspects of mind. The reason why the discussions of the conscience and selfish mind are more systematically described than the Human Mind and Moral Mind seems to be that issues relating to the conscience and selfish mind are more directly applicable to matters of religious doctrine.

  • Purpose: This study aims to draw the problems and improvements of NFSC 103 sprinkler head discharge obstruction prevention standard to increase the fire extinguishing performance of sprinkler system in order to contribute to the protection of people's lives and property in the event of a fire. Method: NFSC 103 was compared to NFPA 13 which is the latest 2019 version in U.S in terms of sprinkler head discharge obstruction prevention. Results: This study found that NFSC 103 doesn't define even the basic concept of sprinkler discharge obstruction. And NFSC 103 doesn't have detailed standard for side wall sprinkler head discharge obstruction prevention as well as the "height" criteria of the "three times" separation rule. Conclusion: NFSC 103 needs a lot of supplements and improvements such as the addition of definition for water discharge obstructions, the adoption of sidewall sprinkler heads standard for preventing water discharge obstructions and the additional establishment of the "three times rule" considering the "height" of obstacles to promote the advance of fire safety standard equal or above fire fighting advanced country and increase the reliability for the suppression performance of sprinkler system.

  • Our society nowadays sees the increase in damage from crime on lives and properties by leaps and bounds in line with the economic take-off, and as a result, the raise of individual income. When considering such a hike in crime, it is desirable that the police framework be enhanced. However, thanks to the failure to correspond to this, it could be safely said that a good portion of accountability was shifted to the private security industry in regard to security for the people. Accordingly, the request for escort security business is on the increase regarding expansion and improvement about this industrial sector. As such, it is necessary to get the related system rearranged for authority on the part of escort guards, who are directly exposed to numerous crimes. On top of this, dispersion is required for the escort security businesses centralized in the metropolitan area. It is also necessary for the security guard system to be strengthened and disintegrated into details so that the escort security services are available to people in more safe and easily manners than ever before. When the qualification regime is operated based on this refreshed system, the efficient escort security work would be realized. The dichotomy into act on Special Security Guard and act on Security Business should be dealt with once again for integration as an issue on the front burner in the academic area, and through which the escort security market could be fit for the globalization as well. This paper would provide the solution that leads to more professional and efficient results from comprehension of progress situations in reality by starting from the concept on private security to the analysis of the conditions in this industrial sector.

  • There are numbers of unpredictable risk factors in the disaster scenes such as fire, explosion and fail to early life-saving or holding the flames which can lead to massive damage. In particular, fire-fighters who arrive on the scene within 5 minutes after dispatching, have a limitation to get aware to the situation of scene fully, because of immediate deploy to disaster scene with limited information. This situation may lead to disturbance that fire-fighters perform effective fire-fighting activities, to put fire-fighter's life at risk by misjudge the situation. Previous domestic and International studies focused vulnerability for spatial area or features which can damage to life and property in the event of anticipated. In this study, we have been developed fire-fighting vulnerable zone model that can analyze comprehensively hindrance factors for fire-fighting activities targeting whole life cycle of fire-fighting activities from dispatch to fire suppression or life-saving. In addition, we have been given shape to finality and applicability for our model by defining the new concept of fire-fighting vulnerable zone which can be distinguished from the concept of fire vulnerable area in previous studies. The results of this study can be used to analysis fire-fighting vulnerable zone type analysis, establish fire-fighting policies and improve the performance of decision-making process.

  • Everyone knows the importance of environmental education, which is essentially required especially today. In particular, the education could influence greatly students who have to get in their class and they might build their own thought on the basic concept regarding environment and ecosystem through their elementary school period. But the current elementary education has not the independent subject of 'environment' but only refers to other courses some dealing with it, leading to the highly possible failure of achieving comprehensive and concrete approaches toward environmental education. In that sense, it will be meaningful that based on existing academic discussions and approaches about various environmental issues facing our society, we seek desirable directions for environmental education at primary school for sustainable development that is needed in this era and its possible applications. The concept of sustainable development that puts an importance on the harmony between the development of environment and its preservation should be rather the one which helps to satisfy desires of the future and now generation together and also emphasizes that environmental protection should be primarily considered even in the situation in which economic development could be seen necessary. Therefore, the key to environmental education for sustainable development lies in building the attitude respecting 'life and nature' and such value will be accomplished through education.

  • One of the current issues in Workers' Compensation Insurance is about the coverage range. Korea uses the definition of worker under the Labor Standards Act in Workers' Compensation Act and solved the problems associated with the coverage range of insurance group by the exceptional clause only for the groups which was raised about the need for the social protection. The purpose of this paper is to draw implications for solving problems which are associated with the coverage range of insurance group by reviewing the German literature. We focus on volunteers and persons in special types of employment. German government supports the activity of volunteers by providing with the protection service against the accidents. This paper shows how the coverage range is extended from the dependent employees in the introduction of the Workers' Compensation Insurance to the people who need social protection focusing on the volunteers. The implications of this research are following. First, German system shows that Workers' Compensation Insurance can be extended to the groups which do not belong to the dependent employee but are worthy of protection. Second, it is necessary to provide volunteers in the social welfare system with the protection service against the accidents and the statutory accident scheme is recommendable to use. Third, volunteers in the social welfare system need to be compulsory insured. Fourth, Korea should find their own way in solving problems associated with persons in special types of employment.
