Purpose: This study examined the relationships between organizational silence, organizational commitment, organizational justice, and organizational citizenship behavior among clinical nurses. Additionally, it determined the mediating effect of organizational commitment moderated by organizational justice on the relationship between organizational silence and organizational citizenship behavior among clinical nurses. Methods: A total of 160 clinical nurses were recruited from a university hospital. Data were collected from June to July, 2023. The collected data were analyzed using descriptive statistics, independent t-test, one-way ANOVA, Scheffé test, Pearson’s correlation coefficient, Baron and Kenny’s three-step regression analysis, Hayes’ PROCESS macro model, and bootstrapping using SPSS/WIN 27.0 program. Results: Organizational commitment had a full mediating effect on the relationship between organizational silence and organizational citizenship behavior (B=-0.04, CI [-0.098~-0.001]). Among the subscales of organizational justice, distributive justice had a moderating effect on the relationship between organizational silence and organizational commitment (B=-0.17, p=.009). There was no significant mediating effect of organizational commitment moderated by organizational justice on the relationship between organizational silence and organizational citizenship behavior. Conclusion Appropriate strategies are needed to effectively manage nursing personnel and improve nursing performance.

BACKGROUND: Ambulatory blood pressure monitoring is widely available in clinical practice. To evaluate the pattern of normal 24 hour variation of blood pressure and the problems in analysis of data which was obtained with use of automatic blood pressure recorder, 24 hour ambulatory blood pressure was measured. METHODS: Ambulatory blood pressure was recorded for 24 hours with automatic blood pressure monitor in 22 normotensive young adolescents. RESULTS: 1) Average 24-hour BP was 109mmHg in systolic(115+/-30 for male, 102+/-30 for female), 66mmHg in diastolic(69+/-18 for male, 63+/-19 for female) and pulse rate was 72 beats per minute(70+/-23 for male, 75+/-26 for female). 2) Data obtained from ambulatory blood pressure monitor should be analyzed after deletion of unacceptable data with use of conventional criteria. Blood pressure increase which is not accompanied by increase in pulse rate increase can be used as another criteria to rule out unacceptable blood pressure data. 3) Blood pressure was low from mid-night to 6 A.M. and began to rise slowly till mid-day and then maintained steadily through the remainder of the day. And 24 hour variation of blood pressure was more adequately assessed after application of Fourier analysis. CONCLUSIONS: These results suggest that certain deletion criteria was inevitable during analysis of the data which were obtained from ambulatory blood pressure recorder and Fourier analysis can be used as valuable smoothing technique to assess the 24-hour blood pressure profiles.

Objectives: An increasing emphasis has been placed on the integration of clinical data and patient-generated health data (PGHD), which are generated outside of hospitals. This study explored the possibility of using standard terminologies to represent PGHD for data integration. Methods: We chose the 2020 general health checkup questionnaire of the Korean Health Screening Program as a resource. We divided every component of the questionnaire into entities and values, which were mapped to standard terminologies—Systematized Nomenclature of Medicine Clinical Terms (SNOMED CT) version 2020-07-31 and Logical Observation Identifiers Names and Codes (LOINC) version 2.68. Results: Eighty-nine items were derived from the 17 questions of the 2020 health examination questionnaire, of which 76 (85.4%) were mapped to standard terms. Fifty-two items were mapped to SNOMED CT and 24 items were mapped to LOINC. Among the items mapped to SNOMED CT, 35 were mapped to pre-coordinated expressions and 17 to post-coordinated expressions. Forty items had one-to-one relationships, and 17 items had one-to-many relationships. Conclusions We achieved a high mapping rate (85.4%) by using both SNOMED CT and LOINC. However, we noticed some issues while mapping the Korean general health checkup questionnaire (i.e., lack of explanations, vague questions, and overly narrow concepts). In particular, items combining two or more concepts into a single item were not appropriate for mapping using standard terminologies. Although it is not the case that all items need to be expressed in standard terminology, essential items should be presented in a way suitable for mapping to standard terminology by revising the questionnaire in the future.

Primary malignant lymphomas of the salivary glands are uncommon. The parotid gland was most frequently involved, followed by the submandibular gland, minor salivary glands and sublingual gland. The most common subtype is mucosa-associated lymphoid tissue (MALT) lymphoma. MALT lymphoma is a relatively indolent disease and tends to remain localized for prolonged period of time. But, we experienced a case of a multifocal salivary MALT lymphoma involving both parotid glands and right submandibular gland during its progression of disease. We report a case with a review of the literature.

Impaired fasting glucose (IFG) is one of significant risk factors of developing diabetes. The persons with IFG are, thus, an important target group for primary prevention of diabetes. It is well known that plasma homocysteine concentration may be increased in poor folate nutritional status. Elevated level of plasma homocysteine is considered as a marker of enhanced oxidative stress. In addition, the protective effect against oxidative stress may be diminished in poor antioxidative nutrient status as vitamin C. It is, therefore, important to maintain adequate nutritional status of folate and vitamin C in the patients with type 2 diabetes or IFG. This study was performed to determine the effects of supplementation of folic acid or vitamin C on plasma concentrations of homocysteine, oxidized LDL, and lipids and on the activity of plasma anti-oxidative enzyme in patients with IFG. A total of 97 patients with IFG were participated voluntarily with written consents. They were divided into one of the four experimental groups; Control (C), Folatesupplemented (F), Ascorbate-supplemented (A), and Folate plus ascorbate-supplemented (FA). The subjects in C were taken placebo, those in F were supplemented 1 mg of folate, those in A were received 1,000 mg of vitamin C, and those in FA were given 1 mg of folate plus 1,000 mg of vitamin C daily for 4 weeks. No change in plasma concentrations of vitamin C, lipids, and oxidized LDL and the activity of GSH-Px were observed in vitamin C-supplemented group (A + FA) and folate-supplemented group (F + FA) compared to the placebo group (C + A). Only the folate-supplemented group (F + FA) had significantly increased average serum folate concentration and lowered plasma homocysteine concentration compared to the placebo group (C + A). Thus, it should be recommended the patients with IFG to increase folate intake through diets and, if it is not sufficient, to take folic acid supplements to prevent the development of complications induced by hyperhomocysteinemia as well as oxidative stress.

PURPOSE: Our purpose was to compare maximum relative cerebral blood volume (rCBV) with histologic grade of cerebral gliomas. MATERIALS AND METHODS: First-pass perfusion MR imaging was performed preoperatively in 16 patients with pathologically proven cerebral gliomas (7 glioblastoma, 2 anaplastic astrocytoma, 1 anaplastic oligo-dendroglioma, 5 low-grade astrocytoma, and 1 low-grade oligodendroglioma). Maximum rCBV was com-pared with histologic diagnosis and grade of the tumor. RESULTS: Maximum rCBVs of glioblastomas were in the range of 433%-1330% (average, 790%), as compared with those of contra-lateral normal white matters. Maximum rCBVs of two non-enhancing anaplastic astrocytomas were 66% and 284%, respectively. Maximum rCBV of one well-enhancing anaplastic oligodendroglioma was 502%. Maximum rCBVs of low-grade astrocytomas were in the range of 80%-369% (average, 202%). Maximum rCBV of one low-grade oligodendroglioma was 1450%, even higher than those of glioblastomas. CONCLUSION: Maximum rCBV was higher in glioblastoma than in low-grade astrocytoma without overlap-ping. However, there was no difference of maximum rCBV between non-enhancing anaplastic astrocytoma and low-grade astrocftoma.

This study examined all the research published in Journal of Korean Academy of Nursing (JKAN) for last 30 years, from its beginning year to year 1999, based on an objective frame of evaluation. The purpose of this study is to reflect the trend of nursing research in Korea to date, and to provide an optimal direction for future research. The total number of 959 studies were analyzed with the following results. 1. Since 1990s, the number of non-degree based research has been larger than that of degree-based research compared to 1970s and 1980s. Both collaborative and funded research has been particularly increased in a gradual rate. 2. Research on nurses or nursing students has decreased while research on more diverse populations such as patients, patient families, or community-dwelling healthy clients has increased. 3. While essential nursing concepts such as human, nursing, and health have been consistently dealt as main research topics, research related to the concept of environ- ment has been insufficiently conducted. 4. It was remarkable that the quality of nursing research has been improved due to the acknowledgement of the importance of the empirical research method within the nursing community. 5. Qualitative research has appeared in the journal since the late 1990s, but it is still regarded to be in its novice stage. 6. Although the utilization of research findings for expanding the nursing body of knowledge has been wide in diverse specialties, most studies are limited to focus on concept development or evolution yet. also, in some of these research finding are utilization already considerably as to develop nursing interventions. Based on these findings, conclusions are extended to the following discussions: For the last 30 years, nursing research in Korea has shown an acute methodological development in both quantity and quality. However, there has been a lack of research on theory development although it is one of the ultimate goals in nursing. Further research should be empirical enough to be utilized in an actual nursing care context, and thus to be basis of developing culturally competent nursing theories in Korea.
