Recently, interest and necessity for the insect industry has been increasing. Insects, which are referred to as the second food, are being used in various fields. Interest in mass production of insects has been increasing in various fields, and the need for research on environmental analysis for them is also increasing. In some countries in other developed countries, automated breeding systems have been developed that incorporate IoT. However, it is limited to be applied to many kinds of insects, and the price is so expensive that it has not been utilized in farm households. Therefore, we have carried out a study to make an optimal system that can be used practically in a farmhouse. Protaetia brevitarsis used for medicinal and edible purposes.

The purpose of this study was to verify the educational effects of career guidance classes, which are now included in regular course offerings by universities. To this end, the self-efficacy of college students regarding career decisions and their degree of career maturity was measured as effect variables. The subjects of the study included 33 sophomores who took 15 weeks of career guidance classes provided by four-year universities. Pretest-posttest design and the paired t-test were conducted for verifying the differences before and after taking career guidance courses. According to the results of the analysis, first, university students' self-efficacy in career decision-making was higher after taking the career guidance courses, indicating a statistically significant difference. Second, the t-value for the difference before and after taking the career guidance courses was indicating that there was a slight statistically significant improvement. These results are meaningful in that they proved that career guidance courses in higher education had the educational effects of improving self-efficacy in career path decisions and the career maturity of college students.

In order to observe the endemic status of Clonrchis sinensis infection in Samrangjin eup, Milyang gun, Kyongsang nam do, a total number of 294 stool specimens were collected from the inhabitants who lived in the basin of the Nakdong river. The specimens were examined by cellophane thick smear technique and Stoll's egg dilution technique during the period from May to June 1983. The epidemiological status was analysed statistically by the regression equation and catalytic curv with the results obtained from this area. The results are as follows : 1) The infestation rate of Clonorchis sinensis in 294 was 49.0%. 2) No remarkable difference was observed between male (52.5%) and female (44.8%). 3) Average E.P.G. by Stoll's egg dilution technique in this area was 9,597. 4) The degree of the intensity of Clonorchis infection by E.P.G. count was distributed as 10.5% in very heavy infection, 14.7% in heavy infection, 47.4% in moderate infection, and 29.3% in light infection. 5) The intensity of endemicity in this area was represented with the regression equation calculated with the cumulative percentages of E.P.G. counts. Regression equation was y=3.40+1.23 log x and Cs. $D._{50}$ was 19.99. 6) The two stage catalytic model was applied and the calculation lead to the equation $y=1296(e^{-0.008t}-e^{-0.035t})$ ; a=0.035 > b=0.008 in this surveyed area. 7) Other helminthic infection rate in this area was 7.1% in A. lumbricoides, 9.5% in T. trichiura and 4.1% in E. vermicularis respectively.

Recently, the spreading business of AMI (Advanced Metering Infrastructure) remote metering systems in various regions of the country has been activated, and it provides various metering functions such as two-way communication and security plan functions for power demand management. Current AMI system is difficult to analyze based on the existing RDB(Relational Database) due to the increase in the size of new internal IoT devices and networks. This study proposes a new GDB(Graph Database) based failure analysis method that utilizes existing RDB data. It analyzes the correlation of new failure patterns through accumulated data such as internal thresholds and status values. As a result of GDB-based simulation, it was confirmed that RDB can predict to a new obstacle pattern that was difficult to analyze.

The purpose of this study is to identify the effects of the apply of lumbar stabilization exercises and lumbar strengthening exercises using Medx machine on back functions such as static balance, lumbar reposition sense, and back pain(VAS) in chronic low back pain. This study divided 30 chronic low back pain patients who experienced only lumbar back pain(male: 5, female: 10) into a lumbar stabilization exercise group and a complex exercise group, and then performed their respective exercise programs for three times a week over a 8-week period. The lumbar static balance, lumbar reposition sense, and lumbar back pain were measured using a pair t-test within each group, and were also compared between two groups using an independent t-test. The results of the present study were as follows: Both groups exhibited statisti cally significant increases after performing their own exercise program in the static balance, lumbar reposition sense, and lumbar back pain(p<.05). However, the comparison of two groups confirmed that the complex exercise group resulted in greater effects than the lumbar stabilization exercise group(p<.05). In conclusion, muscle strengthening and stabilization exercises in chronic low back pain patients are considered to not only relieve back pain, but also improve various back functions.
