  • Recently, cutting-edge ICT technologies such as artificial intelligence, blockchain, edge computing, and the Internet of Things have been applied in various fields to create new services and a new digital era. Along with these technological developments, various policies are being implemented in Korea to transform the country from a "Smart City" to a "Platform City". We can create new services and values by linking with the Smart City Integrated Platform and Smart Housing Platform. This paper defines a linkage scenario between a Smart Housing Platform and the Smart 119 Emergency Dispatch Support Service, one of the Smart City Safety Nets. We propose a data transmission protocol and a metadata schema for data exchange between the Smart Housing Platform and the Smart City Integrated Platform to provide the Smart 119 Emergency Dispatch Support Service.

  • This study was conducted to compare health and nutritional status of 45 home-living elderly people receiving free Meals on Wheels (MOW) (13 men, 32 women) and 81 low income class elderly people receiving free congregate meals (CM) (10 men, 71 women) served in Seoul. Data were obtained from questionnaires, anthropometry and interviews for the 24-hour dietary recall methods. There were no significant differences between the two groups in age and body mass index. Education level, type of housing, family type and income of the two groups also were not significantly different. In MOW, frequencies of exercise were lower while the prevalence of stroke, respiratory disease and loneliness were higher, compared with the CM. The scores of ADL, IADL and food habit of MOW were lower than those of CM. The average daily nutritional intake of both MOW and CM were as a whole under the DRI for Koreans. Energy and macro-nutrient intakes of MOW were tended to be lower than CM (except protein intakes for female). Ca, K, vitamin A, vitamin $B_1$, vitamin $B_2$, vitamin C and folate intakes of MOW were less than 50% of DRI. Percentages of subjects consuming energy less than 75% of EER and 4 nutrients intakes less than EAR were higher in MOW (42.2%) than in CM (1.2%). Our results indicated that dietary nutritional status of MOW was very poor, especially in the case of female elderly groups. For the welfare of the home-living elderly people receiving free MOW, meal service programs should be improved in quality of diet by national supports.

  • Purpose: The purpose of this study was to evaluate the dietary potassium intake, Na/K intake molar ratio, consumption of 18 food groups, and foods contributing to potassium intake of Korean adults as well as the relationships among quartile of potassium intake level and blood pressure, blood biochemical index. Methods: This study was conducted using the Korea National Health and Nutrition Examination Survey, 2007~2010. The total number of subjects was 20,291. All analyses were conducted using a survey weighting to account for the complex survey design. Results: Overall average intakes of potassium were 2,934.7, 3,070.6, 3,078.1, and 3,232.0 mg/day, and they significantly increased by year in Korean adults. The average dietary potassium intake was close to adequate intake (AI), whereas that of women was considerably lower than the AI. The Na/K intake molar ratio in males (2.89~3.23) was higher than in females (2.62~2.95). The major food groups contributing to potassium intake were vegetables, cereals, and fruits/meats. The two major foods contributing to potassium intake were polished rice and cabbage kimchi. The rankings of food source were as follows; polished rice > cabbage kimchi > potato > oriental melon > sweet potato > seaweed > radish > apple > black soybean. In 50~64 year old females, systolic blood pressure (SBP) significantly decreased (p < 0.01) and HDL-cholesterol significantly increased (p < 0.05) as potassium intake increased. Triglyceride (TG) was significantly higher in the other quartile of potassium intake level than in the first quartile (p < 0.05). Conclusion: In conclusion, our study suggests the need for an appropriate set of dietary reference intakes according to caloric intake by sex and age groups and for development of eating patterns to increase potassium intake and decrease sodium intake.

  • The purpose of this study was to investigate the blood concentrations of lipids, insulin and ascorbic acid, and their correlations in obese college men in Gyeongnam area. The blood pressure was significantly higher (p<0.001) in the obese group($127.8{\pm}7.2/86.7{\pm}9.2\;mmHg$) than the control group($112.8{\pm}6.6/71.9{\pm}6.6\;mmHg$). The serum triglyceride (p<0.01), total cholesterol (p<0.01), LDL-cholesterol (p<0.05), insulin (p<0.001) concentrations and atherogenic index (AI) (p<0.001) were significantly higher in the obese group ($158.8{\pm}79.7\;{\mu}U/L$, $185.0{\pm}26.8\;{\mu}U/L$, $111.9{\pm}28.1\;{\mu}U/L$, $15.2{\pm}5.6\;{\mu}U/L$, $3.6{\pm}1.0$) than the control group($111.9{\pm}35.8\;{\mu}U/L$, $165.9{\pm}19.4\;{\mu}U/L$, $97.0{\pm}16.4\;{\mu}U/L$, $8.9{\pm}4.4\;{\mu}U/L$, $2.6{\pm}0.3$), but HDL-cholesterol concentration was significantly higher (p<0.01) in the control group($46.5{\pm}7.2\;{\mu}U/L$) than the obese group($41.3{\pm}6.9\;{\mu}U/L$). On the other hand, there was no significant difference in the plasma ascorbic acid concentration in both groups. The ascorbic acid concentration was negatively correlated with total cholesterol level in the control group, and with triglyceride, total cholesterol levels and diastolic blood pressure in the obese group (p<0.05). These data show that young adult obesity might be related to hyperlipidemia, atherosclerosis, hypertension and diabetes mellitus, and that the nutrition of ascorbic acid is more important for obese males than normal weight males.

  • This study was aimed to investigate the changes in textural properties of Korean radish and relevant chemical, enzymatic activities during salting. During salting, pH was decreased and total acidity was increased. The maximum compression and puncture forces of Korean radish were decreased significantly whereas cutting force was increased. From the force-distance curves, the break point and maximum force point disappeared in salted Korean radish whereas these appeared apparently in fresh one. Also, the number of peak obtained by three types of test from salted Korean radish was decreased. Hot water soluble pectin and 0.4% Na-hexametaphosphate soluble pectin were increased whereas 0.05 N-HCl soluble pectin were decreased significantly. Polygalacturonase activity were increased in Korean radish solid(RS) and Korean radish juice(RJ) until 4 days of salting. Pectin esterase activity were decreased in RS and RJ. Cx-cellulase activity did not appear initially, however, they began to show their activities after 2 days of salting and were increased in RJ although it was low.

  • The effects of aloe on liver function and lipid metabolic disorders induced by alcohol consumption were studied in rats using aloe power (0.25%, 0.5%, 1%) and 10% ethanol. 35 Sprague-Dawley (male, 4 weeks old) rats were divided into five groups and fed experimental diets for six weeks. Body weights of rats tended to be lower in all alcohol supplemented groups than in the control. Food intakes and dry feces per day were significantly lower in all alcohol supplemented groups than in the control. Atherogenic indices (AI) were highest in the alcohol group and decreased in proportion with aloe amount. Serum triglyceride level was significantly higher in the alcohol group than in the control, but tended to be lower in the aloe supplemented groups. In relation to liver function, glutamate oxaloacetate transaminase (GOT), glutamate pyruvate transaminase (GPT), and alkaline phosphatase (ALP) activities tended to be higher in the alcohol groups than in the control, but lower in the aloe groups, especially in the alcohol+0.5% AO group. The levels of liver cholesterol were significantly lower in the alcohol group than in the control and aloe supplemented groups. In the histochemical evaluation, fat droplets appeared extensively on the liver-lobule in the alcohol group, whereas they decreased slightly in the alcohol+0.25% AO group and apparently disappeared in the alcohol +0.5% AO. On the other hand, fat droplets appeared again on the liver-lobule in the alcohol+1% AO group, but were reduced compared with the alcohol group. Regarding the fatty acid composition of adipose tissue triglycerides, the level of linoleic acid (18:2) was significantly higher in the aloe supplemented group. Regarding the fatty acid composition of liver phosphatidylcholine (PC), the level of linoleic acid was higher in the alcohol group and alcohol+1% AO group than the other groups. In contrast, the level of arachidonic acid was significantly lower in the alcohol group. As a result, arachidonic / linoleic acid ratios were significantly lower in the alcohol group compared to the control group, whereas the ratios of the aloe supplemented groups were similar to that of the control group. Therefore, aloe had some beneficial effects on lipid metabolic disorders induced by alcohol and affected desaturation of fatty acids.

  • The importance of bamboo as raw material for bamboo wares and several kinds of industrial products is highly appreciated at home and abroad. But different kinds of bamboo-bundle systems have been traditionally used in the local areas. There being no reasonable bamboo-bundle system, we have a lot of difficulty in trading bamboo products and executing adrinistmative works. Therefore, a reasonable bamboo-bundle system based on scientific proofs needs to be tested and established for fair trade and administration. This study is carried out to solve the above difficulty with statistical investigation and analysis. The results obtained are as follows. 1. The larger the circles at eye-height become, the more the possibility of the largest internode covering the span between eye-height and 1/4 height increases. 2. The longest internodes are distributed according to a rule without relation to circles at eye-height. 3. The tapering grade of bamboo culms is very high and its form is almost the same without relation to its size. (Form exponent; 0.71-1.05, eye-height form factor; 0.60-0.66, 1/4 becomes, seeing that the circle grade and the percentage of actual volume height form factor; 0.61-0.69). 4. The larger the circles at eye-height are, the lower the percentage of actual volume have negative curve relation to each other. 5. It is considered that the numbers of bamboos bundled in a "Sok" is not decided according to the usefulness of bamboos, judging from the fact that the outputs of bamboo wares per "Sok" in every circle grade are not the same. 6. As the results of the regression analysis, the empirical formulae of several amounts to circles at eye-height and culm length are as follows; Volume, $${\hat{y}}_i=\bar{3}.821874+2.013181log\;C_i+0.839128log\;H_i$$ $$V=0.0066355\;C^{2.013181}\;H^{0.839128}$$ Actual volume, $${\hat{y}}_{ai}=3.915338+0.776549log\;C_i+1.857000log\;H_i$$ $$V_a=0.0082288\;C^{0.776549}\;H^{1.857000}$$ Weight, $$w_i=3.869148+1.936410log\;C_i+0.566904log\;H_i$$ $$W=0.0073986\;G^{1.936410}\;H^{0.565904}$$ 7. Korean Phyllostachys bambusoides Sieb. et Zucc. is almost the same as that of Japan in several amounts, just the same especially in the weight. 8. It is found that the bamboo-bundle systems of Korea and Japan have much closer relation to the weight than other amounts. So It is, therefore, considered that the weight is important factor in deciding bamboo-bundle system. 9. According to the item 8, I should like to propose the appropriate numbers per "Sok" adjusted on the basis of the weight in the Table 18.

  • Many people with disabilities have shown interest in artificial intelligence speakers that serves as the main hub of the smart home. Therefore, the purpose of this study was to identify the intention of people with disabilities to use such speakers. The focus is on those with physical disabilities, a segment that accounts for the largest number of disability types. Based on the theoretical model of technology acceptance, the effect of perceived ease of use and perceived usefulness of artificial intelligence speakers by people with disabilities was analyzed using Structural Equation Modeling (SEM). Research has confirmed that the technology acceptance model is suitable for identifying the intention to use artificial intelligence speakers by people with disabilities, and specifically that the perceived ease of use has a significant impact on usefulness. Furthermore, the perceived ease of use for people with disabilities did not have a statistically significant effect on their intent to use whereas the perceived usefulness was shown to have a significant effect on the same. This study is meaningful as a foundation for developing customized artificial intelligence speaker services and improving the use of artificial intelligence speakers by people with disabilities.

  • The purpose of this study is to analyze the current situation of EduTech, which is proposed as a way to build a flexible learning environment regardless of time and place according to the use of digital technology in mathematics subjects. The process of designing classes to use the EduTech platform, which is still in the development introduction stage, in public education is still difficult, and research to observe its effects and characteristics is also in its early stages. However, in the stage of preparing for future education, it is a meaningful process to grasp the current situation and point out the direction in preparation for the future in which EduTech will be actively applied to education. Accordingly, the current situation and utilization trends of EduTech at home and abroad were confirmed, and the functions and roles of EduTech platforms used in mathematics were analyzed. As a result of the analysis, the EduTech platform was pursuing learners' self-directed learning by constructing its functions so that they could be useful for individual learning of learners in hierarchical mathematics education. In addition, we have confirmed that the platform is evolving to be useful for teachers' work reduction, suitable activities, and evaluations learning management. Therefore, it is necessary to implement instructional design and individual customized learning support measures for students that can efficiently utilize these platforms in the future.

  • This study was conducted to examine beauty shop workers' views of job. Data were collected from the workers in Seoul, Daegu, Pohang, Junjoo, and Kimhae from June 1, 2000 to August 31, 2000. The results of this study are summarized as follows. 1. According to general characteristics of the subjects, 28,7% of them was female; 94.2% 'specialized in hair'; 46.4% 'below twenty nine years old'; 47.1% 'married'; 59.7% 'highschool graduate'; 33.9% 'worked for below three years'; 28.5% 'monthly income of five hundred thousand to nine hundred ninety thousand won'; 62.3% 'working for above twelve hours a day' ; 41.0% 'above five workers' ; 40.6% 'working in city'. 2. 54.8% of the respondents thought that they were in good health. 76.3% of them smoked and 54.8% drank. 62.8% of them did not exercise and 78.7% was under stress. 61.5% responded that they chose the job because of its possibility of professional vocation. 91.0% of them obtained the beauty skill from beauty schools. 3. Among the factors which influenced job satisfaction, 'stable job and life security' was highest(43.9%), while 'interest in the job and amount of pay' was lowest(3.2%). 'Personal ability and use of originality' was 19.4% and 'harmonious relationship with fellow workers' was 18.1%. 'Job environment' was 7.1% and 'harmonious relationship with higher workers' was 4.5%. 4. The level workers' view of job was $113.8{\pm}17.3$ points on the basis of 150 points. On the basis of 75 points, each item showed it points in order of self-development($22.3{\pm}3.8$), service for customers($20.1{\pm}3.1$), vocational mission($15.6{\pm}3.1$), harmony with the others($18.9{\pm}3.5$), working environment($18.6{\pm}3.6$), and working condition($14.3{\pm}5.1$). 5. Among the reasons why they considered leaving the job, 24.0% of them considered it because they could not free time, while 15.4% considered it because undesirable living environment or long distance from home. 15.0% thought it because they could not receive proper treatment as much as they worked and 12.8% thought they overworked. 6. When they move into new working places, they consider such factors as good working environment(24.1%), good place to open their own beauty shops(16.7%), good beauty shop to learn beauty skill(15.6%), chance to have job training(9.5%), and close place from home(9.0%). 7. 40.6% of the respondents wanted to leave the job, while 32.3% of them did not want to leave the job. The intention of leaving the displayed significant difference in the variables of age, working period, monthly income, marital status, the number of workers, location of the shop, rank, and reason of selecting the job. 8. According to the results of a regression analysis of factors which influenced job satisfaction, it was affected significantly by intention of leaving job, the number of workers, health condition, level of stress, and monthly income. The beauty shop workers showed low satisfaction level with working environment, working condition, and working mission, They considered leaving the job because of lack of free time, overwork, poor working environment, improper treatment, etc. Therefore, related professionals and organizations must device adequate measures in order to make them work with pride as creators of beauty.
