The purpose of this study was to suggest valuable maker education programs by implementing and evaluating a Home Economics(HE) maker education program developed based on the content of "Hanbok and Creative Clothing" for high school students. The results of this study are as follows. First, the HE maker education model for high school students was designed and developed. The HE maker education model was developed by integrating and modifying the TMSI model of the maker education model and Laster's HE practical action teaching model. The HE maker education model consisted of 4 steps: tinkering(T: 4-hour class), practical reasoning(P: 3-hour class), making together(M: 4-hour class), and sharing and spreading(S: 1-hour class) with a total of 12-hour lesson plans. The theme of the developed HE maker program is 'Practice and spread of creative traditional culture of life (Hanbok)'. Second, the results of online survey of 240 high school students who participated in this maker class showed that HE maker class had positive effects in the order of experiential(4.26), cognitive(4.22), emotional(4.18), social(4.18), and practical(4.10). It is expected that the findings of this study will contribute to diversifying the curriculum of Home Economics, thereby improving the quality of Home Economics Education.

1. King Hyeonjong(1641-1674) mainly suffered from eye disease and abscess. He specially took a hot spring bath for cure of eye and skin problems. He probably died of septicemia and the following gastro-intestinal infection at the age of 34, quite early for his age. 2. King Sukjong(1661-1720) was not very well all through his life, but lived quite longer than other Kings in the Joseon Dynasty. He suffered from various diseases like heart-based heat, abscess, edema, upper respiratory infections, etc. He frequently took the treatments of acupuncture and moxibustion. He presumably died of dysfunction of liver and kidney at the age of 60. 3. King Gyeongjong(1688-1724) suffered from political problems from birth to death, so he may have had excessive mental stress for his poor health. He mainly suffered from heart-based heat and abscess. It is quite not sure why he died in only one month from the onset of his symptoms, so many people thought that he was poisoned to death. He probably died of septicemia and the following gastro-intestinal infection at the age of 37. 4. King Yeongjo(1694-1776) lived for 83 years, which is the longest of all the Kings in the Joseon Dynasty. He mainly suffered from hypofunction of gastro-intestinal system with cold symptoms, coughs, uneasiness. He took various kinds of herbal medicine, of which he took ginseng the most. He is supposed to be dead due to his old age at 83.

Ovarian cancer is a highly malignant neoplasm with high mortality rates. Research to identify markers facilitating early detection has been pursued for many years. Currently, diagnosis is based on the CA 125 and HE4 markers, as well as the ROMA algorithm. The search continues for new proteins that meet the criteria of good markers A total of 90 patients were included in the present study, allocated into: group 1, ovarian cancer, with 29 patients; group 2, endometrial cysts, with 30s; and group 3, simple ovarian cysts, with 31. Following histopathological verification, the CA 125, HE4, and metalloproteinase 3 (MMP3) levels were determined and the ROMA algorithm was calculated for all patients. The mean concentrations of all determined proteins, CA 125, HE4, and MMP3, as well as the ROMA values, were significantly higher in group 1 (ovarian cancer) compared to group 3 (simple ovarian cysts). The highest significant differences for the CA 125 levels (p<0.000001) and ROMA (p<0.000001) values were observed in postmenopausal women. For HE4, statistical significance was at the level of p=0.00001 compared to p=0.002 for MMP3. For the differentiation between ovarian cancer and endometrial cysts, the respective AUC ratios were obtained for CA 125, HE4, and MMP3 levels, as well as the ROMA values ( 0,93 / 0,96 / 0,75 / 0,98). After removing the post-menopausal patients, the MMP3 AUC value for ovarian cancer vs. benign ovarian cysts increased to 0.814. For post-menopausal women, the MMP3 AUC value for ovarian cancer vs. endometrial cysts was 0.843. As suggested by the results above, both the CA 125 and HE4 markers, as well as the ROMA algorithm, meet the criteria of a good diagnostic test for ovarian cancer. MMP3 seems to meet the criteria of a good diagnostic test, particularly in postmenopausal women; however, it is not superior to the tests used to date.

The purpose of this study was to identify a support method for the introduction of metaverse-based classes (MBC) in home economics (HE) education. This was achieved by diagnosing the stages of concern and levels of use exhibited by HE teachers applying the concerns-based adoption model (CBAM). Questionnaires were sent to a convenience sample of middle- and high-school HE teachers using the KSDC (Korea Social Science Data Center). Overall, 271 responses were received, and the data were analyzed using KSDC E-STAT 3.0 and SPSS 28.0.1.1. The results were as follows: First, regarding the level of knowledge of MBC, the introductory level was the most common (139 respondents, 51.3%,), followed by the beginner level (81, 29.9%), the intermediate level (28, 10.3%,), the advanced level (12, 4.4%), and the master level (11, 4.1%). Average responses on a 5-point Likert scale to questions about the use of metaverse in HE classes were as follows: possibility (4.02), necessity (3.82), and usefulness (3.90). Second, HE teachers' stages of concern in MBC were as follows (in descending order): unconcerned - stage 0, and information - stage 1 (86.9), personal - stage 2 (85.6), management - stage 3 (80.9), collaboration - stage 5 (57.5), consequence - stage 4 (57.4), and refocusing - stage 6 (55.2). Third, the use of MBC was highest for orientation - level 1 (173 respondents, 63.8%), followed by non-use - level 0 (34, 12.5%), preparation - level 2 (29, 10.7%), mechanical - level 3 (15, 5.5%), refinement - level 5 (8, 3.0%), renewal - level 7 (8, 3.0%), routine - level 4 (3, 1.1%), and integration - level 6 (1, 0.4%). Many HE teachers had heard about MBC but were in the introductory level of not knowing what it is, and at the stage of being unconcerned or wanting to know about MBC. Of the 271 respondents, only 35 used metaverse in classes. Therefore, it is necessary to provide teacher training opportunities that provide basic information on the significance and implementation of MBC for HE teachers. Also, an MBC guideline book should be developed and distributed to HE teachers. Finally, a teacher community meeting is needed to share the expertise of teachers with substantial experience in using MBC.

Celecoxib, a selective inhibitor of COX-2, showed cytotoxic effects in many cancer cell lines including cervical cancer cells. This study investigated the effect of celecoxib on cell cycle arrest in HeLa cervical cancer cells through p53 expression. In vitro anticancer activity was determined with the 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide (MTT) method. A double staining method was applied to investigate the mechanism of cell death, cell cycling was analyzed by flow cytometryand immunocytochemistry was employed to stain p53 expression in cells. Celecoxib showed strong cytotoxic effects and induced apoptosis with an $IC_{50}$ value of $40{\mu}M$. It induced cell cycle arrest at G2/M phase by increasing level of p53 expression on HeLa cells.

In this study, the change of temperature, chemical composition, and helium gas of thermal water in Pohang area was observed from January 2018 to June 2019 in order to interpret the relationship with earthquake events. During observation period earthquakes above M 2.0 within 100 km in a radius from a geothermal well occurred 58 including two earthquake events with a magnitude of 3.0~3.9 and two earthquake events with a magnitude of 4.0~4.9. We introduce a q-factor and earthquake effectiveness (ε) to express the influence of each earthquake as magnitude and distance factors. The geothermal well of 715 m deep was developed in the Bulguksa biotite granite, and the water temperature was observed in the variation from 51.8 to 56.3℃ during monitoring period. At M 4.1 and M 4.6 earthquake events, the increase of geothermal water temperature (𝜟T 2.6~4.5℃) was recorded, and slight change in specific ionic components such as SO₄ and Cl, and of chemical types on the Piper diagram were observed. In the ³He/⁴He vs ⁴He/²⁰Ne diagram, the original mixing ratio of helium isotope before and after the magnitude 4.1 earthquake was slightly changed from 83.0% to 83.2% of crust-origin ⁴He, and the from 16.3% to 16.7% of mantle-origin ³He. Hot-cold water mixing ratio before and after earthquakes by using the quartz and chalcedony solubility curves of the silica-enthalpy mixing model was calculated to interpret the temperature change of geothermal water. The model calculation shows the increase of 6.93~7.72% and 1.65~4.94% of hot water ratio at E1 and E2 earthquakes, respectively. Conclusively, the magnitude of earthquake for observable change in the temperature and helium isotope of thermal water is of 4.1 or higher and q-factor value of 30.0 or higher in the study site.

Objectives: Treating complex regional pain syndrome (CRPS) is difficult because it still does not have a recommended therapy. A 29-year-old man was diagnosed with CRPS after surgery on his $4^{th}$ and $5^{th}$ left toes 7 years ago. Though he had undergone diverse pain treatment, the symptoms persisted, so he visited Dunsan Korean Medicine Hospital of Daejeon University. This case report presents results on the effect of bee venom pharmacopuncture in treating patient with CRPS. Methods: Bee venom pharmacopuncture (BVP), 0.15 to 0.4 mL dosage, was administered at GB43. The treatment was applied each week for a total 14 times. The symptoms were evaluated using a numeric rating scale (NRS) and the dosage of pain medicine. Results: On the first visit, he was taking an anticonvulsant, a trycyclic antidepressant, and an analgesic. On the NRS the worst pain in the toes received a score of 8. He also complained of severe pain and hypersensitivity when the $4^{th}$ and the $5^{th}$ toes were touched just slightly. Other complaint included dyspepsia, rash, and depression. After treatment, on the NRS, the score for toe pain was 0, and he no longer needed to take pain medication. During the 4-months follow-up period, he has remained without pain; neither have additional symptoms appeared nor adverse events occurred. Conclusion: BVP may have potential benefits for treating patients with CRPS.
