STATEMENT OF PROBLEM: How the ISQ values measured by Osstell(TM) and Osstell(TM) Mentor are related, and whether the ISQ values acquired from the two machines changes in accordance with changes in implant stability are not yet fully understood. PURPOSE: The aim of this study was to find out correlation between the ISQ values acquired from Osstell(TM) and Osstell(TM) Mentor, and to evaluate the clinical effectiveness and accuracy of two devices. MATERIAL AND METHODS: Sixty two implants were inserted into 47 patients, and their ISQ values were measured using Osstell(TM) and Osstell(TM) Mentor. In the first stage surgery, the ISQ values of forty four implants inserted into thirty five patients were measured. In the second stage surgery, the values of fifty implants inserted into thirty seven patients were measured. The values were analyzed to determine the difference between the mean ISQ values of Osstell(TM) and Osstell(TM) Mentor. In addition, the correlation between implants used in the first and second stage of surgery with regard to their types and areas of insertion were analyzed. The difference between the ISQ values of 32 implants in each patient during the first and second stage was analyzed. The statistical assessment was carried out using SPSS V. 12.0 for Win. (SPSS Inc., Chicago, USA). The Pearson correlation coefficient was used to examine the correlation between Osstell(TM) and Osstell(TM) Mentor in the first and second stages of surgery, whereas the difference between their ISQ values was evaluated using a paired t-test. RESULTS: In the first stage, the mean ISQ value for Osstell(TM) and Osstell(TM) Mentor was 70.84 and 75.09, respectively, showing a significant difference (P < .01). In the second stage, the mean ISQ value of Osstell(TM) and Osstell(TM) Mentor was 71.76 and 75.94, respectively, also showing a significant difference (P < .01). The difference between the ISQ values in patients in the first and the second stages was significant with both instruments. CONCLUSION: The significant difference in the values obtained using the Osstell(TM) and Osstell(TM) Mentor between the first and second stages of implant surgery indicates that these values can be a convenient and precise way for evaluating the implant stability in clinical practice.

To generate drug delivery vector to locales in the body, genetic engineering and expression techniques have been used to produce antibody avidin fusion proteins. Chicken avidin has been fused to mouse-human chimeric IgG3 immediately after the hinge with a flexible linker (H-Flex-Av) and at the end of CH2 (CH2-Av). Fusion heavy chains were expressed with the expected molecular weight, assembled as H2L2 forms with a co-expressed light chain, and were secreted. The expression level of H- Flex-Av was 1~10 ug/ml/10(8)/24 hrs, but that of C2-Av was a very little (0.08~0.9 ug/ ml/10(8)/24 hrs). The resulting H-Flex-Av and CH2-Av fusion proteins continued to bind antigen dansyl and also bound biotinylated bovine serum albumin; both H-Flex-Av and CH2-Av had shown to retain 3-4 times higher relative affinity than that of CH3-Av in ELISA. Importantly the fact that both avidin fusion proteins had a higher relative affinity suggests that these avidin fusion proteins can be effectively used to deliver biotinylated ligands such as drugs and peptides to a certain locale, such as the brain.

Development of antibody-based cancer therapies will be greatly facilitated if antibodies are better standardized in two fundamental issues that are specificity analysis of antibody reactivity and the detailed biodistribution and pharmacokinetic profile of antibodies. In the current endeavor we attempted to use an antibody binding specificity to target the tumor in a syngeneic carcinoembryonic antigen (CEA) tumor model. CEA, a 180 kDa glycoprotein, expressed at high levels on the surface of nearly all tumors of the gastrointestinal tract was used a potential target for antibody immunotherapy of gastrointestinal carcinomas. Using the CEA model antibody-based cancer therapy directed against CEA has been evaluated in a syngeneic animal model of disseminated disease. We constructed mouse/human chimeric anti-CEA IgG3, which has been evaluated for the specificity for CEA and the detailed biodistribution and pharmacokinetic profiles. Anti-CEA IgG3 heavy chain was expressed with the expected 180kDa molecular weight, assembled as H2L2 forms with a co-expressed mouse/human chimeric anti-CEA light chain, and were secreted. On FACS the purified anti-CEA IgG3 specifically recognized the mouse colon adenocarcinoma cell line MC-38 transduced with CEA (MCA32a), but not MC 38 without expressing CEA. After subcutaneous injection in C57BL/6 mice the half- lives of anti-CEA IgG3 and an irrelevant anti-dansyl IgG3 showed the bi-phasic kinetic patterns, and their pharmacokinetics of the distribution and the elimination were similar in mice. However, the biodistribution patterns of anti-CEA IgG3 were very different from those of anti-dansyl IgG3. Anti-dansyl IgG3 was mainly distributed into kidney until 72 hours, but anti-CEA IgG3 was slowly rernoved from blood and distributed into liver, kidney, spleen, and tumor. It is note worthy that anti- CEA IgG3 increased in targeting MCA32a tumor expressing human CEA by time, but the targeting to MC38 tumor was negligible. Thus, the increased targeting of anti- CEA IgG3 made MCA32a tumor grow slowly

This study was a descriptive research in search of a nursing intervention scheme to improve stroke patients' quality of life by understanding the relationship of stroke patients' ADL. depression, self-efficacy and quality of life with various variables and identifying factors that affect their quality of life. Each subject was interviewed one to one based on a structured questionnaire. With regard to research tools, Modified Barthel Index (MBI: Fortinsky et al., 1981), which was translated by Choi, Hye-sook (996), was used in measuring ADL, Randloff's (1977) tool. which was translated by Choi, Soon-hee, was used in measuring depression, and the tool developed by Sherer et al. (1982), which is to measures self-efficacy under general conditions not limited to specific conditions, and modified by O, Bok-ja (1994) was used in measuring self-efficacy. The quality of life was measured using the scale of satisfaction of life developed by Diener et al.(1985). The results of this study were as follows: 1. The means of ADL of the subjects was 79.5+/-1.9, depression 26.8+/-0.4. self-efficacy 47.1+/-5.7, and the quality of life 12.3+/-.9. 2. The subjects' quality of life showed a statistically significant difference according to gender (t=7.9, p= .006), satisfaction with income (F= 5.8, p = .004), the burden of medical fee (F=3.7, p= .028) and the period of disease (F=2.8. p= .042). 3. With regard to relationship among ADL, depression, self-efficacy and the quality of life, ADL was in a relatively low positive correlation (r= .293, p= .003) with and the quality of life, depression in a high negative correlation (r=- .634. p= .000) with the quality of life. and self-efficacy in a positive correlation with the quality of life (r= .388. p= .000). 4. Factors that made a significant influence on the quality of life were depression (8=- .309. p= .001) and satisfaction with income (8=-2.611. p= .001). Based on these results, this study made following suggestions: 1. It is necessary to run rehabilitation programs to improve stroke patients' ADL, depression and self-efficacy. 2. It is necessary to perform research of monitoring stroke patients' quality of life in various areas using measuring tools.

5.Factors Affecting Blood Pressure and Stress according to the Alcohol Use Disorders Identification Test Scores among Undergraduate Students.
Journal of Korean Biological Nursing Science 2017;19(4):215-226
PURPOSE: The purpose of this study was to investigate the effects of general, health, and alcohol-related characteristics on blood pressure and stress according to the Alcohol Use Disorders Identification Test (AUDIT). METHODS: This was a descriptive study. From participants in the 2013 Korea National Health and Nutrition Examination Survey, 319 participants who responded to the survey when they were attending college or university were selected. Data were analyzed using the SPSS Win 23.0 program for composite sample data reflecting the composite design elements of stratification, colonization, and weighting. RESULTS: Mean age of onset of alcohol drinking was 17.91±0.16 years, the average AUDIT score was 7.56±0.41, and 25 (9.1%) participants fell into the high-risk drinking group. In the high-risk AUDIT group, systolic blood pressure was influenced by age, gender, institution, health status, body mass index, and suicidal ideation, and the explanatory power of the model (R2) was 75.0%. For diastolic blood pressure, institution and health status were the influential factors, and R2 was 66.2%. Predictors of stress were health status, depression, and the age of onset of drinking, and R2 was 57.2%. CONCLUSION: It was confirmed that the explanatory power of the variables in models of systolic and diastolic blood pressure and stress is greater in those with higher scores on AUDIT.

6.The effect of aromatherapy on pain in individuals with diabetes: a systematic review and meta-analysis
Journal of Korean Biological Nursing Science 2024;26(2):71-82
Purpose:
This study systematically analyzed the impact of aromatherapy on pain in individuals with diabetes. Methods: A search was performed in seven electronic databases based on the PICO-SD (Population, Intervention, Comparison, Outcome, Study Design) framework. The population (P) of interest was individuals with diabetes, and the intervention (I) included aromatherapy targeting pain reduction. The comparison (C) consisted of control groups that received no intervention, another intervention, or usual care. The outcome (O) measured was pain. The quality of the selected literature was assessed using the Joanna Briggs Institute checklist. In MIX 2.0 Pro, the pooled overall effect of pain was calculated using Hedge's g and a random-effects model, and heterogeneity was calculated using the Q statistic and Higgin's I2 values. Meta-regression and exclusion sensitivity analyses were performed.
Results:
Five articles and seven studies were included, showing a significant pooled overall effect of aromatherapy on diabetes-related pain (Hedge’s g = −1.83, 95% CI: −2.76 to −0.91). Meta-regression demonstrated that effectiveness in reducing pain was associated with studies conducted in West Asia, those with IRB approval, and those receiving funding. Additionally, interventions involving subjects under 60, lavender oil (vs. turpentine oil or blended oils), massage therapy (vs. topical application), fewer hours per session, and more repeated measurements (vs. pre/post measurements) were associated with pain reduction.
Conclusion
Aromatherapy, especially with lavender oil, effectively manages diabetes-related pain. Short-duration massage application is also effective. A personalized selection of oil type and application method could optimize therapeutic outcomes for individuals with diabetes.

PURPOSE: The study was to examine the effects of the individual education about chemotherapy for cancer patients as well as their family who are receiving the first chemotherapy on self-care knowledge, self-care performance, family support, and anxiety level. METHODS: A non-equivalent control group was used in this interventional study. A total of 50 patients with cancer aged above 19 in the K university hospital, Seoul, Korea, participated in the study (Experimental group: n=25, Control group: n=25). The education about chemotherapy was offered one week after hospital discharge, which was followed by telephone counseling Data were analyzed by the SPSS/WIN 20.0 program using percentage, frequency, mean, standard deviation, x2 test, and independent t-test. RESULTS: The experimental group showed a significantly better self-care knowledge (t=4.094, p < .001), self-care performance (t=3.532, p=001), family support (t=2.170, p=.035), and anxiety control (t=4.780, p < .001) than the control group. CONCLUSION: The findings suggest that the individual education should be considered for cancer patients and their family in the clinical fields.

Korean Journal of Dermatology 1992;30(3):279-290
Thirty two cases of nevus sebaceus were studied by immunohistochemical staining employing three anticytokeratin antibodies(34bE, 34bB, CAM 5.2) and anti-involucrin antibody in order to clarify the biochemical characteristics of the covering epidermis of nevus sebaceus. An attempt was made to compare the expression pattern of these proteins in the epidermis of nevus sebaceus with that in normal skin and in epidermal nevus. Serial sections in all cases were also stained with PAS in attempt to correlate these protein expression with the amount of glycogen in the epidermis of nevus sebaceus. The following results are obtained. 1. The expression of cytokeratin and involucrin in the epidermis of nevus sebaceus was changed as the age of the lesions increased, but we could not identify a uniform pattern according to the age of lesions. 2. Several CAM 5.2 positive cells were found in the basal layer of the epidermis of nevus sebaceus lesion obtained from patients over 10 years of age. 3. The expression of cytokeratin and involucrin did not show any correlation with glycogen content. These results suggest that the covering epidermis of the lesion of nevus sebaceus may not be nevoid proliferation of epidermal nevus.
