The objective of this study is to report an accidental detection of colorectal cancer (CRC) metastasis to spine during conservative treatment for lumbar disc herniation. We treated a 65-year-old female who was diagnosed with lumbar disc herniation on September 2019 by acupuncture, pharmacopuncture, cupping treatment, chuna manual therapy, herbal medicine treatment, medicine treatment and physical therapy. After that we analyzed medical record from December 12, 2019 to February 11, 2020. The patient was diagnosed with CRC and received tumor resection in 2014. After 2 times of chemotherapy, she arbitrarily interrupted the treatment. Since she stated that CRC treatment was terminated, we had difficulty in finding connection between symptom and CRC. During the treatment period, compression fracture at L3 body was found, which was caused by CRC metastasis. Rigorous question, appropriate radiological and clinical tests are required to patients who have history of malignant tumor.

The lack of characteristical understanding of the Home Economics Education will have difficulty in achieving the goal of the Home Economics Education. To allow the Home Economics Education class in school contribute toward the enhancement of the quality of life, it is inevitable to reinforce the recognition of the importance and necessity of the Home Economics Education and to newly propose a directional guidance forward the coming 21st century. The purpose of this study was to provide basic data for planners of the future Home Economics Education by surveying research administrators in charge of programming the overall school curriculum. This study was conducted under the following procedure to have the outcome as follows ; 1. Answers from respondents of age over 50 or careers over 16 years tended to grasp the goal of Home Economics Education in relation to the enhancement of quality of life rather than to the accumulation of knowledge, skill or capacity. 2. Of all the surveyed, 9.64% regarded Home Economics Education as an essential part of school education and the positive ratio was higher with younger respondents. 3. To the question asking if the high school Home Economics Education could have influence on one's capacity, 97.2% of the answerers said yes. The respondents with career under 15 year showed 100% of positive agreement in this matter and of age under 40 marked much higher ratio of 98.84% than the elders. 4. The overall recognition of the necessity for separate sections in Home Economics Education programmed in accordance with the 6th Revision of High School Curriculum displayed a considerably high ratio, with a little differences among age and job groups.

Various items were used as evaluation tools that identify the student's abilities accurately to confirm the completion of learning. Among them, the multiple choice item has the advantages of high objectivity and reliability in scoring, but it cannot remove the factor of guessing. In this paper, the multiple choice items are classified into two types according to the relationship between the questionnaire and the choices. One is the type used in the classical test theory with the probability of guessing 1/k for k choices and the other is the novel proposed type which introduces the concept of partial knowledge. In the proposed type, the probability of guessing when the number of knowledge i is (i+1)/k for k choices. Based on the assumptions of the previous theories about multiple choice items, we derive the guessing parameter about the proposed type. And we analyzed the effect of the guess on the correct answer in the existing type and the proposed type. This shows that the proposed type has more question guessing than the existing type.

Background: The clinical significance of lip-tie, or a tethered maxillary frenulum, remains under debate. Clinicians and parents are often perplexed when deciding whether procedures available to relieve a seemingly tight or severe maxillary frenulum are needed. Purpose: No previous studies have assessed the consequences of not subjecting a tethered maxillary frenulum in newborns to surgical intervention. This study aimed to contribute the first prospective trial on this topic with a relatively extended follow-up of these newborn infants. Methods: This prospective observational questionnaire-based cohort trial was performed in a community setting and aimed to determine whether lip-tie is associated with an increased likelihood of eventual feeding or oral disorders. Results: The convenience sample comprised of 61 consecutively arriving infants with concomitant tethered frenula who were treated at the clinic for various reasons. This cohort was compared with a random sample of 66 age-matched children for a mean follow-up period of 6.42 years. Infants undergoing oropharyngeal procedures were excluded. Awareness of a deviation in oral structures was reported by 18% of the study group versus 0% of the controls. Mothers participating in the study group (24.6%) less frequently recalled painful nipples or discomfort during breastfeeding than those in the control group (47.0%) (P<0.01). There were no intergroup differences in other types of feeding difficulty, dental hygiene, pronunciation, or speech development. Conclusion: Our findings suggest that a tethered labial frenulum is not associated with an increase in breastfeeding disturbances or oral disorders. These data encourage clinicians to question the need to intervene in cases of tethered maxillary frenula.

Although students can make their questions to clarify their curiosity, there are variety of reasons why a student cannot ask a lecturer. For example, they are ashamed to ask questions. In particular, in case of the class to attend many students, the situation for the difficulty of the question will be caused even greater. Recently, in order to overcome this problem, the Audience Presentation Program (APS) to share students' questions and comments have been introduced, it has widely used. The APS system enables students to ask questions more easily and comfortably. In this paper, we have analyzed the effect of the APS system on the basis of questionnaires in terms of easy-to-use, preference, engagement, etc. According to the results of this paper, we found that all students were satisfied with the APS system.

This study has produced a checker of the shortest path search problem with a total of 19 questions as a web-based computer evaluation based on the 'TRAFFIC' questions of PISA 2012. It is because the computer has been settled as an indispensable and significant instrument in the process of solving the problems of everyday life and as a media that is underlying in assessment. Therefore, information gifted students should be able to solve the problem using the computer and give clear enough commands to the computer so that it can perform the procedure. In addition, since it is the age that the computational thinking is affecting every sectors, it should give students new educational stimuli. The relationship between the rate of correct answers and the time took to solve the problem through the shortest route search process showed a significant correlation the variable that affected the problem solving as the difficulty of the question rises due to the increase of nodes and edges turned out to be the node than the edge. It was revealed that information gifted students went through algorithmic thinking in the process of solving the shortest route search problem. And It could be confirmed cognitive characteristics of the information gifted students such as 'ability streamlining' and 'information structure memory'.

This study started with wondering whether the nonproportional model used in unit assessment for 2nd graders is appropriate or not for them. This study aims to explore the applicability of the nonproportional model to 2nd graders when they learn about numbers. To achieve this goal, we analyzed elementary mathematics textbooks, applied two kinds of tests to 2nd graders who have learned three-digit numbers by using the proportional model, and investigated their cognitive characteristics by interview. The results show that using the nonproportional model in the initial stages of 2nd grade can cause some didactical problems. Firstly, the nonproportional models were presented only in unit assessment without any learning activity with them in the 2nd grade textbook. Secondly, the size of each nonproportional model wasn't written on itself when it was presented. Thirdly, it was the most difficult type of nonproportional models that was introduced in the initial stages related to the nonproportional models. Fourthly, 2nd graders tend to have a great difficulty understanding the relationship of nonproportional models and to recognize the nonproportional model on the basis of the concept of place value. Finally, the question about the relationship between nonproportional models sticks to the context of multiplication, without considering the context of addition which is familiar to the students.

The purpose of this study was to determine factors affecting intention to participate in school breakfast programs of middle and high school students in Seoul using the Theory of Planned Behavior. Out of 2,280 questionnaires distributed to the middle and high school students, 2,060 were returned (90.4% response rate) and 1,799 were analyzed (78.9% analysis rate). To determine factors affecting intention to participate in school breakfast programs, logistic regression analyses were conducted for middle and high school students, respectively. For logistic regression, data of 1,217 out of 1,799 students (637 middle and 580 high school students) were used after excluding 582 students which had an answer 'Not sure' to the question about intention to participate in school breakfast programs. In case of middle school students, male than female students (OR = 1.504), the students who skipped all breakfast (OR = 1.851), who ate breakfast $1{\sim}2$ times (OR = 3.474) or $3{\sim}4$ times (OR = 1.950) than those who ate breakfast everyday during weekdays of the previous week were more likely to participate in school breakfast programs. In case of high school students, male than female (OR = 1.967), the students who skipped all breakfast (OR = 4.187), the students who ate breakfast $1{\sim}2$ times (OR = 3.024) or $3{\sim}4$ times (OR = 2.095) than those who ate breakfast everyday during weekdays of the previous week were more likely to participate in school breakfast programs. In addition, both possibility of middle and high school students' participation in school breakfast programs increased as the satisfaction with school lunch service (OR = 1.704, 1.653) increased. Middle school students who perceived their household income level 'low or middle low' (OR = 1.999) than those who perceived their household income level 'middle' and the students who had more positive 'attitude' (OR = 1.311) toward eating breakfast were more likely to participate in school breakfast programs. However, high school students who had higher 'perceived difficulty in access to breakfast' (OR = 1.370) were more likely to participate in school breakfast programs. The results of this study could be useful data to plan and develop school breakfast programs in Korea.

This study intended to find out how the handicapped use medical aid, their satisfaction at using it and so on. First a preliminary survey(Apr. 20$\sim$24, 2002) was made for the handicapped who had been cured for rehabilitation by wearing medical aid at hospitals and welfare center in Jeonbuk region. Then total 120 subjects were asked to fill out a standardized questionnaire from May 15$\sim$22, 2002. Out of total 95 questionnaires collected, 84 questionnaires were analyzed except for 11 cases unsuitable for the intention of this study. The results can be outlined as follows: 1. In general characteristic, it was found that the causes of disability included disease(35 respondents; 41.7%), traffic accident(23 respondents, 27.4%) and so on. In addition, 1st handicap comprised the majority(32 respondents; 58.2%) in handicap grade and ankle foot orthosis(or b-k orthosis) was most often used as medical aid(28 respondents: 33.3%) 2. In particular, it was also shown that the 1st handicap mainly resulted from traffic accident(15 respondents, 27.3%) and post-disease disability (11 respondents, 20.0%). They wore medical aid for 1 year or less on the average, because they were hospitalized for cure, which showed statistically significant level(P<0.05). 3. It was found that total 69 respondents(82.1%) were more or less satisfied with their medical aids depending on the causes of disability, and total 46 respondents(83.6%) were satisfied with their aids according to their handicap grade, but there were no statistical significance. 4. Total 56(66.7%) respondents answered that they would purchase medical aid on their own expenses, when they became handicapped. And the price of medical aid ranged from $\300,000{\sim}400,000$(25 respondents: 29.8%) to \ 500,000 or more(24 respondents: 28.6%). It means that they purchased more or less expensive medical aid on their own expenses, which showed statistical significance(P<0.05). 5. If there was any failure of medical aid, 9 respondents(37.5%) answered that they would be serviced from medical companies, and 7 respondents(29.2%) would be serviced from medical aid manufacturers. Most respondents were serviced for their medical aids from related companies. For the question about the causes of dissatisfaction upon repair service, 11 respondents(45.8%) answered that existing service company provided unskilled repair services and other respondents answered that there was no spare part or higher service expenses than they thought. These answers had the statistical significance(P<0.05). However, 20 respondents(79.2%) answered that they were satisfied with the repair service, which means that most respondents are satisfied with the service. In view of the results as described above, it can be concluded that their handicap or disability results from disease or sequelae after traffic accident and most of the affected wear their own medical aid. In the future, it is required that the medical insurance should cover those medical aids, and the service for failed medical aids should be commissioned by technical serviceman to realize customized manufacture and repair service according to different causes so that the handicapped can enjoy more or less comfort and convenience in their daily lives without any extreme difficulty.
