We have examined the effects of mayonnaise on the lipid metabolism and calcium bioavailability of rats by using myonnaise. Sprague Dawley male rats(131$\pm$5g) were divided into four dietary groups[Control (Con, 10% soybean oil), Mayonnaise(M5), 10% Mayonnaise(M10)and 15% Mayonnaise(M15)] were fed ad libitum with experimental diets for four weeks. Final body weight exhibited a decrease in the M10 group, also final thymus organ weight showed a significant decreasing trend(p<0.05). The levels of serum, liver and adipose total lipid were significantly different among the four experimental groups(p<0.05). Serum calcium levels were significantly lower in the M15 group than in among the groups(p<0.05). On the other hand, the elevation of serum cholesterol levels were not clearly observed, but triglyceride levels were elevated the M5 and M15 group. The P/S ratio of adipose tissue were higher in the M10 group(2.35$\pm$0.35) than any other groups. Free EDTA in mayonnaise was 0.0307~0.0387%, moisture 12.46~16.49% and calcium 0.012~0.019%. But commercial mayonnaise contained free EDTA higher than the safe use (0.0075%). Safety problems of EDTA additives resulted from mass processed mayonnaise are arising. Though the evaluation of safety can not reach a conclusion with only one or two clinical case studies. It often simply jumps to conclusion. Therefore more wide ranged discussion and deepened study is required to search for the solution of safety problems.

Purpose: The purpose of this study was to investigate the effects of aromatherapy on the level of anxiety and fatigue in student nurses who were undergoing their first clinical practice. Method: A non-equivalent. control group. pretest-posttest design was used. A convenience sample of 42 student nurses were selected. They were assigned to experimental and control groups. The aromatherapy using lavender, geranium and camomile was given to the experimental group for four consecutive days while the control group only rested. Result: 1. Anxiety scores for the experimental group were significantly lower than those of the control group on the $2^{nd},\;3^{rd}$ and $4^{th}$ days of clinical practice. 2. Fatigue scores for the experimental group were significantly lower than those of the control group on the $2^{nd},\;3^{rd}$ and $4^{th}$ day of clinical practice. Conclusion: The results support the conclusion that aromatherapy using selected essential oils is an effective intervention for relieving anxiety and fatigue in student nurses experiencing their first clinical practice. However differences between aromatherapy and massage were not clear. Further investigation needs to be done.

Statement of problems. There are only a few studies available that deal with the clinical behavior of ceromer systems as potential substitutes for metal-ceramic crowns. Purpose. This prospective study was initiated to evaluate the clinical performance of 35 Sculpture crowns after 2 years in service. Material and methods. Thirty five Sculpture crowns were placed for 20 patients (7 men and 13 women). All patients were treated by the same dentist, and all restorations were fabricated by the same dental laboratory. Crown placement involved both the anterior and posterior regions of the dental arches. Patients were evaluated by two examiner at baseline, 12, and 24 months using the CDA quality assessment system in addition to periodontal criteria. Results. Of 34 crowns remaining in the study after 2 years, only one crown had experienced a marginal fracture. The crown was replaced as a result of recurrent caries. All remaining crowns were ranked as either excellent or acceptable for surface and color, anatomic form, and marginal integrity. Conclusion. The 2-year clinical observations and ranking with the CDA quality assessment criteria supported the conclusion that Sculpture crowns may be used in substitutes for metal-ceramic crowns.

Purpose: This study was conducted to compare pain, sense, bleeding, and hematoma that patients feel depending on the process of eliminating air of pressure band that was applied to patients after percutaneous coronary intervention (PCI) through radial artery. Methods: It was a nonequivalent control group pretestposttest design to compare pain, sense, bleeding, and hematoma by amount and time of eliminating air of pressure band after PCI through radial artery. Results: On arrival at Coronary Care Unit, meaningful difference didn't exist between pain and sense, however, after two hours of starting eliminating air, the points of pain and sense were meaningfully low (p<.001). Also, there was meaningful difference in reciprocal action between group and time (p<.001). Conclusion: After PCI, the conclusion showed there is positive effect in decreasing wrist pain and sense without any influence of bleeding by eliminating air from patients' pressure bands.

Purpose : The purpose of this study was to determine the changes in ultrasound imaging of the lower limbs in patients with degenerative osteoarthritis who received a total knee replacement (TKR). Methods : The participants for the study were ten patients who were to receive a total knee replacement. Measurements were taken a total of three times: before receiving a total knee replacement, and one week and two weeks after receiving a total knee replacement. The vastus medialis, rectus femoris muscle, tibialis anterior and gastrocnemius muscle were measured using ultrasound imaging. Results : Muscle thickness of the vastus medialis, rectus femoris muscle, tibialis anterior and gastrocnemius muscle had no significant interaction over time whether surgery was performed or not. White area index (WAI) and density of vastus medialis, rectus femoris muscle, tibialis anterior and gastrocnemius muscle had no significant interaction over time whether surgery was performed or not. Conclusion : In conclusion, lower quality muscles were due to a decrease in muscle fiber and an increase in fat fiber. Therefore, initial physical therapy after total knee replacement should consider this point and be designed appropriately as a therapeutic approach for total knee replacement patients.

Purpose: Alcohol use in South Korean women, particularly college students, is increasing. Women are more vulnerable than men to alcohol use, which puts them at greater risk of physical and psychosocial problems. Some studies have reported that on failing to find meaning in life, many South Korean college students experience depression, subsequently using alcohol as a coping mechanism. This study aimed to develop a logotherapeutic program and identify its effects on meaning in life, depression, and problem drinking among female college students. Methods: This study was a quasi-experimental trial. The participants were female college students who scored over 8 in the Alcohol Use Disorders Identification Test (AUDIT). Twenty-four students were assigned to the experimental group and twenty-three to the control group. Three scales were used in this study: the Purpose in Life test, Beck Depression Inventory, and AUDIT. The data were analyzed using the Mann-Whitney test in SPSS/WIN 12.0. Results: After the conclusion of the logotherapeutic program, the level of meaning in life and depression were more greatly improved in the experimental group than the control group. Conclusion: The logotherapeutic program is an effective method to help female college students find meaning in life and reduce depression in this population.

Objectives: This is a five-year survival and complete response (CR) report on pancreatic cancer treated with western medicine and Korean traditional medicine. Method: A 59-year-old woman diagnosed with pancreatic cancer visited ○○ Korean traditional medicine hospital after neoadjuvant chemotherapy and pylorus-preserving pancreaticoduodenectomy. She was treated with Korean traditional medicine, including acupuncture, abdominal moxibustion, wild ginseng pharmacopuncture, and herbal medicine, which was based on integrated medicine therapy (IMT), from March 2018 to September 2022. The tumor size was measured by scanning with computed tomography (CT), magnetic resonance imaging, and positron-emission tomography/CT. Adverse events were evaluated using laboratory conclusion and National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0. Result: During four years and three months of treatment, IMT maintained safety. The patient finally reached five-year survival without any recurrence or complication (CR) on October 26, 2022. Conclusion: We suggest that an integrative approach including Korean traditional medicine can be a meaningful treatment option for pancreatic cancer. Further studies should be performed to establish the proper treatment protocol of integrative medicine for pancreatic cancer.

Purpose - On the basis of discussing the network economy concept and the commentary of the marginal revenue decreasing of traditional economic theory, The concept of network economy has just been put forward in recent years. The reason why such a concept appears is that the information technology, marked by computer network, plays an increasingly important role in economic activities. Some people define network economy as an economic form based on network technology and human capital. this paper points out network economy existing the marginal revenue increasing and analyzes the reasons that influencing the marginal revenue increasing. Research design, data, methodology - The network economy has fundamentally changed the traditional economic laws. The economic basis of industrial society is the law of incremental marginal cost, which reflects the socialization of high cost in industrial society. Results - As the number of network members increases, the value of the network increases explosively, and the value increases attract more members to join, resulting in more returns. Conclusion - In conclusion, network economy has changed many aspects of traditional economy, resulting in decreasing marginal cost, decreasing transaction cost in and out of enterprise organizations, and making the effect of increasing scale compensation more prominent. This is of great significance to the information construction in China.

Purpose: The central aim of this study is to leverage machine learning techniques for the classification of Intrusion Detection System (IDS) data, with a specific focus on identifying the variables responsible for enhancing overall performance. Method: First, we classified 'R2L(Remote to Local)' and 'U2R (User to Root)' attacks in the NSL-KDD dataset, which are difficult to detect due to class imbalance, using seven machine learning models, including Logistic Regression (LR) and K-Nearest Neighbor (KNN). Next, we use the SHapley Additive exPlanation (SHAP) for two classification models that showed high performance, Random Forest (RF) and Light Gradient-Boosting Machine (LGBM), to check the importance of variables that affect classification for each model. Result: In the case of RF, the 'service' variable and in the case of LGBM, the 'dst_host_srv_count' variable were confirmed to be the most important variables. These pivotal variables serve as key factors capable of enhancing performance in the context of classification for each respective model. Conclusion: In conclusion, this paper successfully identifies the optimal models, RF and LGBM, for classifying 'R2L' and 'U2R' attacks, while elucidating the crucial variables associated with each selected model.
