PURPOSE: The purpose of this study was to explore the clear concept of organizational commitment for effective nursing personnel management. METHOD: This study was conducted using Walker & Avant's conceptual analysis framework(2005). RESULTS: Organizational commitment was identified with six attributes: acknowledgment, acceptance, trust, sacrifice, attachment, regulation. Antecedents of organizational commitment were personal characteristics, perceived organizational support, empowerment, fair compensation, job satisfaction, job autonomy, organizational culture, and leadership. Consequences of organizational commitment were turnover intention, job performance and organizational citizenship behavior. CONCLUSION: Organization commitment is a core concept for understanding the management of nursing personnel. Appropriate instruments to operationalize the concept of organizational commitment including six attributes need to be developed.

BACKGROUND: Monocytes/macrophages play a central role in determining the host response during Gram-negative infection through secretion of a variety of mediators after stimulation of LPS. Even though cytokine production has been shown to play an important role in host defense during sepsis cytokine release may also lead to tissue injury. Thus, regulation of macrophage response to LPS is critical for host survival during Gram-neg-alive sepsis. In animals exposed to nonlethal doses of endotoxin a characteristic hyporesponsiveness to subsequent administration of endotoxin has been observed. This phenomenon was knowm as 'LPS tolerance'. However, little information is availavble regarding the underlying mechanism of U)S tolerance. METHOD: Peripheral blood monocyte(PBMC) was isolated from peripheral blood of normal volunteers by adhesion purification method. To evaluate conditions to obtain LPS tolerance. preculture was carried out with LPS at 10ng/ml for 24 hours. For stimulation culture plates were washed two times and were stimulated with LPS at 1ng/ml for 4, 6 and 26 hours. To assess the underlying mechanisms of LPS tolerance, autologous serum, PMA, anti-CD14 Ab, Indomethacin or PGF2 were added to preculture solution respectively. Cytokine concentrations in culture supernatants were measured using ELISA for TNF-α and IL-8 and mRNA of TNF-α and IL-8 were determined by Northern blot analysis. RESULTS: The exposure of PBMC to low dose of LPS suppressed the cytokine production and mRNA expression of TNF-α, but not IL-8. Anti-CDl4 Ab partially recovered production of TNF-α which was suppressed by preculture with low dose LPS. The preculture with PMA induces US tolerance, as preculture with low dose LPS. CONCLUSION: LPS tolerance to TNF-α is regulated pretranslationally and is influenced by protein kinase C pathway and CD14.

A cross sectional study was performed to evaluate the neurobehavioral effects of chronic exposure of complex organic solvents, using NCTB(Neurobehavioral Core Test Battery) recommended by WHO(World Health organization). Forty female shoe factory workers and twenty-two controls matched with age were participated. The tests were performed in the morning before start of work, to exclude the effects of acute exposure. Workers were exposed mainly to toluene, methyl ethyl ketone, n-hexane, cyclo-hexane, dichloroethylene, trichloroethylene, benzene, xylenes etc. The ranges of present solvent exposure of hygienic effect were 0.46~0.71 in the process using adhesives indirectly, and 1.83-2.39 in the process using it directly. We reclassified the subjects, according to cumulative exposure. It showed significantly poorer performances in high exposed group on Santa Ana Dexterity and Benton visual Retention, compared with control group. After controlling confounder, the significances were still remained. But, further cohort studies, having the information of personal exposure dose from entering a factory, are required to clarify the effects of chronic exposure of complex organic solvents in relation to dose and duration of exposure.

PURPOSE:The objective of this study was to identify the effectiveness of continued breast feeding and maternal identity between rooming-in and not rooming-in groups of mothers in post partum care. METHOD: The subjects were selected by convenient sampling, with 95 women in childbirth completing a questionnaire. The data were collected on the 2nd day after delivery by questionnaire, and after the 4th and 8th weeks by telephone interview. Measures used in this study included general characteristics, breast feeding related characteristics, and the maternal identity scale revised by Koh(1996). The data were analyzed with the SPSS program, and the Chi-test and t-test were used to identify the effect on breast feeding and maternal identity. RESULTS:Continued breast feeding up to 4 weeks after deliverly was not statistically significant between rooming-in and not rooming-in group, but beyond 8 weeks of deliverly, it was significantly different in rooming-in group(p<.01). Maternal identity was significantly higher in rooming-in group than in not rooming-in group(p<.01). CONCLUSIONS: Mothers preferred rooming-in system because it helped breast feeding and baby care. Rooming-in system provides self confidence in taking care of baby, knowledge about breast feeding and stimulates early phase lactation. We recommend rooming-in system in hospitals to promote breast feeding and maternal identity. Nurses are encouraged to discuss prenatal breast feeding before delivery and rooming-in care should be planned individually for continuation of breast feeding and formation of maternal identity.

BACKGROUND: Diffuse panbronchiolitis(DPB) is a chronic inflammatory lung disease of unknown etiology which has characteristic clinical, radiological and pathological features, and is distinguished from bronchial asthma, chronic bronchitis, pulmonary emphysema, bronchiectasis, or alveolitis. Clinically, patients with DPB have chronic cough, purulent sputum, exertional dyspnea, and finally respiratory failure. Until a few years ago, the prognosis of DPB had been thought to be very grave, because there had been no effective treatment for the disease. But recently, low-dose long-term erythromycin was found to be very effective on DPB. Even though DPB is prevalent in Japan, and is known to be rare outside of Japan, we have already reported the clinical features of 16 DPB cases in Korea. We tried low-dose long-term erythromycin on DPB patients and analyzed the clinical effect of erythromycin. METHODS: We analyzed the changes of subjective symptoms, physical signs, pulmonary function tests and chest X-rays on 14 DPB patients with more than 6 months erythromycin treatment during the period from September 1989 to August 1992 in Seoul National University Hospital. RESULTS: 1) Subjective symptoms improved in all patients within 2-3 months, and 54.5% of the patients shorted no symptom after one year of treatment. 2) Crackles and wheezing decreased in 92.9% of the patients after 3 months and completely disappeared in 63.5% of the Patients after one year of treatment. 3) FVC and FEV1 increased remarkably during the first 3 months, and slowly increased thereafter, reaching normal level after one year of treatment. 4) Small nodular lesions on chest X-ray decreased in all patients, and chest PA was normal in 36.4% of the patients after one year of treatment. 5) There was side effect in one patient, stopping medication because of dyspepsia. One patient stopped medication because of no symptom after 16 months of treatment, but her symptom recurring after one month, improving again after retreatment. CONCLUSION: Low-dose long-term erythromycin showed ramarkable effectiveness on DPB. Further studies are needed on the mechanism of the drug and the duration of the treatment.

BACKGROUND: The importance of pro-inflammatory cytokines, especially tumor necrosis factor α(TNF-α) and interleukin-1β(IL-1β), have been extensively documented in the generation of inflammatory lung disease. Lung epithelial cells are also actively involved in initiating and maintaining inflammation by producing pro-inflammatory mediators. Understanding the mechanism of pro-inflammatory cytokine expression in lung epithelial cells is crucial to the development of new therapeutic modalities for inflammatory lung disease. Transcription of most pro-inflammatory cytokines is dependent on the actiation of NF-κB. However, the relationship between pro-inflammatory cytokine expression and NF-κB/IκB pathway in lung epithelial cells is not clear. METHODS: BEAS-2B, A549, NCI-H719 cells were stimulated with IL-1β or TNF-α at various times, and then IL-8 and TNF-αmRNA expressions were assayed by Northern blot analysis. IL-1β or TNF-α-induced NF-κB activation was assessed by the nuclear translocation of p65 NF-κB subunit. The degradation of IκBα and IκBβ by IL-1βor TNF-α stimulation was assayed by Western blot analysis. The phosphorylation of IκBαwas evaluated by Western blot analysis after pre-treating cells with proteasome inhibitor followed by IL-1β or TNF-α stimulation. The basal level of IKKα expression was evaluated by Western blot analysis. RESULTS: IκBαand IκBβ was repidly degraded after 5 minutes of incubation with IL-1β or TNF-α in BEAS-2B, A549, and NCI-H157 cells. The activation of NF-κB and the induction of IL-8 and TNF-α mRNA expressions were observed by IL-1β or TNF-α stimulation in these cells. In contrast, neither the changes in NF-κB/IκB pathway nor IL-8 and TNF-α mRNA expression was induces by IL-1β or TNF-α stimulation in NCI-H719 cell. IL-1β and TNF-α-induced IκB phoshorylation was observed in BEAS-2B, A549, and NCI-H157 cells, but not in NCI-H719 cells. The basal level of IKKα expression was not different between cells. CONCLUSION: NF-κB/IκB pathway plays an important role in the ixpression of pro-inflammatory cytokine in most lung epithelial cells. The absence of the effect on NF-κB/IκB pathway in NCI-H719 cells seems to be due to the defect in the intracellular signal transduction pathway upstream to IKK.
