Among the many odor materials, aldehyde has bad influences not only on human nose, but also on human health. Aldehyde has a strong odor at infinitesimal level, such as down to ppt concentration. Also aldehydes are highly reactive and have poor stability. Therefore, manufacture of standard gases, analysis of aldehydes are very difficult compare to other air pollution analysis. Aldehyde CRM containing 4 different aldehydes at $10{\mu}mol/mol$ (ppm) is developed by using gravimetry method according to ISO 6142 guide. The standard gases were reproduced again, and examined its reproducibility of preparation by GC-FID. The developed aldehyde CRM's certified value showed a relative expanded uncertainties of 2.11 % (95 % of confidence level, k=2).

The various environmental regulation directives such as RoHS (restriction of hazardous substances in electrical and electronic products) and WEEE (waste from electrical and electronic equipments) are practically used as the technical barrier in international trade (TBT) of vehicles and electrical and electronic products recently. Regarding such an environmental regulation, Korea Research Institute of Standards Science (KRISS) organized a proficiency testing scheme to establish the reliability of measurement results produced by the relevant research institutes and test laboratories in Korea. Participants were 31 laboratories related to production of the electrical and electronic equipments and mobile vehicles. Two polypropylene samples of pellet type were employed as the proficiency testing materials (PTMs). Cadmium and lead were the analytes chosen among six components regulated in European Union (EU) RoHS directive. The PTMs were sent to the participants by post on September $1^{st}$ 2006, and deadline for results submission were October $10^{th}$ 2006. The results of each laboratory were evaluated in comparison with KRISS reference values using Robustic Z-score and Youden plot methods. The results of the various sample digestion methods were also compared. Most of participants reported good agreement within 10 % range of reference values. However, results from several laboratories showed significant biases from reference values. These laboratories should establish the quality assurance system for improvement of the measurement reliability.

Purpose: We examined the effects of cognitive flexibility, resilience, and professional quality of life on the job embeddedness of nurses. Methods: The participants were 120 nurses in three general hospitals. Data collection was conducted using self-report questionnaires from May 17 to June 2, 2022. Data were analyzed using descriptive statistics, independent t-test, one-way ANOVA, Pearson correlation coefficients, and multiple regression analysis. Results: There were significant differences in job embeddedness by experience of turnover (t=-3.15, p=.002). The factors influencing the job embeddedness of the nurses were compassion satisfaction (β=.44, p<.001), resilience (β=.24, p=.035), experience of turnover (β=.23, p=.002), and cognitive flexibility (β=.21, p=.027). It was found that 39% could explain job embeddedness. Conclusion: It is necessary for nurses' support programs to be related to the experience of turnover to enhance job embeddedness. The results indicate a need to develop a program for cultivating compassion satisfaction, resilience, and cognitive flexibility to improve job embeddedness.

A type of dimethyl disulfide gas CRM in the ppb level was developed for the analysis of tracelevel odorous gas in environmental atmosphere. The concentration of dimethyl disulfide($(CH_3)_2S_2$) was $10{\mu}mol/mol$ level in the cylinder filled with nitrogen, 1500 psi. And the variability of the concentration for 2 years was about 0.14% due to the adsorption or instability of $(CH_3)_2S_2$. The gas standards produced simultaneously in 4 bottles and examined by GC-FID were shown with 0.4%, reproducibility of preparation and 0.25%, standard uncertainty due to weighing and purity. The relative expended uncertainty of 1.1%(95% of confidence level, k=2) was assigned to the certified value of $10{\mu}mol/mol$ level of $(CH_3)_2S_2$ after quantitative evaluation on the purity, mixing, weighing, analysis, adsorption and stability of dimethyl sulfide gas.

세계화가 사회적 불평등을 심화시키고 있지만 이에 대처하는 개별 국가의 능력은 오히려 약화되고 있으며, 그 결과 노인인구층의 복지여건이 악화되고 있다는 것이 종래의 일반적인 인식이다. 본 논문은 이러한 일반적 인식을 재검토하는데 목적이 있다. 검토작업은 다음 네가지 영역에서 이뤄진다. 첫째, 세계화에 대한 상이한 개념정의와 시각을 검토한다. 여기에는 노령층에 대한 복지급여를 잔여적 급여로 전환시키는데 있어 핵심적 역할을 행하고 있는 주요 국제기구의 활동을 중점 논의한다. 둘째, 세계화가 개별 국가에 미치는 영향이 일률적이라는 시각을 재검토하기 위해 세계화에 대해 서로 다르게 반응한 미국과 유럽방식을 비교한다. 셋째, 세계화가 노령화 정책에 미치는 영향에 대해 논의한다. 넷째, '사회적 삶의질'이란 개념을 통해 노인계층의 복지수준은 경제적 성장보다 사회적 급여에 더 큰 영향을 받게 됨을 보여 주고자 한다.

A trace amount of boron in steel significantly influences its mechanical and physical properties. A prompt gamma ray activation analysis (PGAA) method is used to measure boron in low alloy steel samples of KRISS 101-01-C21~C26. NIST SRMs of 362, 364, 1761 and 1767 serve as the control standards to validate the measurement method. The measured values of the NIST SRMs are consistent with their certified values within the expected uncertainties, except for that of NIST SRM 362. Experimental uncertainties are evaluated according to the guidelines given by the International Organization for Standardization (ISO). The expanded uncertainties are calculated with a coverage factor of 2, at approximately 95% confidence level. The calculated relative expanded uncertainties of boron mass fractions are between 3% and 7% at the mg/kg level. The results are compared with the results measured by the solvent extraction-inductively coupled optical emission spectrometry (ICP/OES) method.
