Objectives: This study aimed to survey the characteristics of air quality and meteorological conditions in a greenway park. Methods: We measured meteorological and health related factors, including noise, particulate matter ($PM_{10}$) and selected gaseous air pollutants at three locations in a greenway park and on a general roadside as comparison. The measurements were repeated four times from April to October 2014. Results: The average air temperature in the greenway park was $20.7^{\circ}C$ which was $1-2^{\circ}C$ lower than on the general roadside. The average $PM_{10}$ concentration in the greenway park was $85.0{\mu}g/m^3$, a level 2-3 times lower than that at the roadside. The noise level at the greenway site was 4.4 dB(A)- 23.0 dB(A) lower than at the roadside. The average CO, $CO_2$, $SO_2$ and NOx concentrations in the greenway park were lower than at the roadside. The average phytoncide and anions concentrations in the greenway park were higher than at the roadside. Conclusions: The urban forest of the greenway park may have some impact on air quality and meteorological conditions.

For apartment complexes area, children"s hospital showed the highest integration level whereas park/playground showed the lowest one. However, there was no statistically significant difference. 3) When analyzing accessibility to spaces in multi-family houses area and apartment complexes area respectively according to blocks, it was found that there was a statistically significant difference in integration level of day care center, children"s hospital, and park/playground.

Health Beliefs Associated with Cancer Screening Intentions in Korean Workers

Park, Kyoung-Ok,Kang, Jina Asian Pacific Journal of Cancer Prevention 2016 Asian Pacific journal of cancer prevention Vol.17 No.7

Background: Cancer is a leading cause of death in Korea. To prevent cancer, it is essential to facilitate and promote appropriate cancer screening behavior in the adult population. The aim of this study was to examine health beliefs related to cancer screening intentions using the Health Belief Model (HBM). Materials and Methods: The research participants comprised 275 male health and safety managers at commercial companies in Korea. The self-administered survey explored demographic characteristics, cancer-related factors, beliefs about cancer/cancer screening (BCCS) (vulnerability to cancer, severity of cancer, benefits of screening, and barriers to screening), and cancer screening intention. Multivariate logistic regression analyses were used to identify factors associated with an intention to be screened for cancer. Results: Perceived health status and need for cancer prevention education were major factors associated with BCCS. Poorer health status was associated with greater perceived vulnerability, a perception of fewer benefits, and more barriers (p<0.05). A perceived greater need for cancer prevention education was associated with a higher perceived severity of cancer and more perceived barriers to screening (p<0.05). Marital status, cancer screening experience, and perceived vulnerability to cancer were significant influences on the cancer screening intention (p<0.05). Participants who had undergone cancer screening in the past 2 years were more likely to intend to be screened for cancer than were those who had not been screened; this was true across all degrees of intention and all types of cancer (p<0.01). Hesitant people considered themselves less vulnerable to gastric, lung, and liver cancer than did the poeple who intended to undergo cancer screening (p<0.05). Conclusions: Based on our findings, we recommend that workplace cancer prevention programs attempt to increase awareness about vulnerability to cancer among workers who hesitate to undergo cancer screening.

연구목적: 본 연구는 제조업과 건설업 사업장 노동조합관계자들의 사내 안전보건교육에 대한 인식과 참여정도를 파악하고 이들 간의 관련성을 분석하는데 그 목적을 두었다. 연구방법: 본 연구의 대상은 103명의 노동조합 관계자들(78개 제조업 산업장의 91명, 12지역의 12건설업 노동조합관계자)이었고 이들을 대상으로 자기기입식 설문조사를 실시하였다. 전국기업체산업안전협의회의 회원사들을 중심으로 우리나라 전역의 제조업과 건설업 사업장을 임의로 선정하고 선정된 사업장별로 설문지 2부, 노동부의 설문조사 협조공문, 설문조사 안내문, 설문회수용 봉투로 구성된 우편물을 사업장 노동조합사무실로 발송하는 방식으로 설문조시를 실시하였다. 80% 이상이 소속 사업장 규모가 50인 이상이었고 대부분 이 결혼한 남자로 구성되어 있었다. 설문조사 내용은 대상자와 대상사업장의 일반적 특성, 사업장의 안전보건교육 특성, 노동조합의 사내 안전보건교육 참여도, 노동조합의 사내 안전 보건교육에 대한 인식으로 구성되었다. 연구결과: 전체적으로 제조업사업장에 건설업 사업장에서보다 사내 안전보건교육에 대한 인적, 물적 인프라가 잘 구축되어 있었고 사업주의 사내 안전보건교육에 대한 지원도가 높았으며, 사내 안전보건교육 담당자들의 교육역량에 대한 인식도가 더 높은 경향을 보였다. 이러한 인적, 물적 인프라는 사업장내 노동조합의 안전보건교육 참여도와 정의 상관관계가 있었으며 그 정도는 중등도 이상의 수준이었다. 결론: 이상의 결과를 토대로 볼 때 사업장 안전보건교육에 대한 노동조합의 참여와 지지를 확충하기 위해서는 사업장 조직적으로 안전보건교육 실시에 대한 지원이 선행되어야 함을 알 수 있었다. 아울러 안전보건관리자들을 대상으로 근로자 산업재해에 대한 지식뿐만 아니라 사내 안전보건교육을 수행관리할 수 있는 ‘교육역량’을 기를 수 있도록 연수프로그램을 확충할 필요가 있겠다. Objectives: This study identified the labor union associates' perception and participation status on SHEW and analyzed these two Constructs correlations with Safety and health education at work (SHEW) in manufacture and construction industries. Methods: Self-administered survey was successfully finished by 103 labor union associates (91 employed in 78 manufacturing companies and 12 employed in 12 constructing companies over 12 areas). Two questionnaires, survey direction slip, the official letter to ask survey participation from Korea Ministry of Labor, and a posted envelop to return were delivered to each workplace labor union office in conveniently selected companies. Most participants' companies were at least medium to large in manufacturing industry and most associates were men and married. A survey questionnaire examined demographic characteristics, SHEW status (participation status included), and perceptions of SHEW. Results: Overall, manufacturing companies had better infrastructures for SHEW, employer support for SHEW, and current educators' competencies than constructing companies. These infrastructures for SHEW were closely correlated with company labor union participation on SHEW and the correlation coefficients were greater than any other expectations or needs variables for SHEW. Conclusions: The primary strategies for better participation and support from labor union need to be developed in supporting for organizational infrastructures related to SHEW and strengthening safety and health education training programs for supervisors or educators at work.

To identify an ideal carrier for rhBMP-2 during spinal fusion surgery, we produced a posterolateral rats lumbar fusion model to compare the bone induction potentials of rhBMP in collagen sponge(CS) and rhBMP-2 mixed with insoluble porcine collagen(PC) gel. Forty Sprague-Dawley rats(350-400 grams) subjected to bilateral lumbar intertransverse process fusion were allocated to CS Groups(Groups 1 to 4) or PC gel Groups(Group 5 to 8). Group 1 animals were implanted with CS and injected with 1 ?g rhBMP-2; Group 2 with CS plus 3 ?g rhBMP-2; Group 3 with CS plus 5 ?g rhBMP-2; Group 4 with CS plus 10 ?g rhBMP-2; Group 5 with PC gel containing 1 ?g rhBMP-2; Group 6 with PC gel plus 3 ?g rhBMP-2; Group 7 with PC gel plus 5 ?g rhBMP-2; and Group 8 with PC gel plus 10 ?g rhBMP-2. Spinal fusion masses were evaluated by manual palpation, radiographic assessment, microcomputer tomographic scanning, and histologically at 8 weeks after surgery. Bone fusion was radiologically confirmed in 50% in Group 3, 66% in Group 4, 16.7% in Group 5, 20% in Group 6, 80% in Group 7, and 100% in Group 8. Treatment with PC gel plus rhBMP-2 resulted in higher spinal fusion rates than CS plus rhBMP-2 based on manual palpation, microCT, and histologic examinations(P < 0.01). In this study, the mixing of gelatin gel and rhBMP-2 resulted in more effective lumbar intertransverse process fusion than injecting collagen containing rhBMP-2.

The role of methylenetetrahydrofolate reductase C677T polymorphism on the peripheral blood natural killer cell proportion in women with unexplained recurrent miscarriages

Park, Chan-Woo,Han, Ae-Ra,Kim, Joanne-Kwak,Park, So-Yeon,Han, Jung-Yeol,Koong, Mi-Kyoung,Song, In-Ok,Yang, Kwang-Moon The Korean Society for Reproductive Medicine 2011 Clinical and Experimental Reproductive Medicine Vol.38 No.3

Objective: To examine the association between methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism and hyperhomocysteinemia in women with unexplained recurrent miscarriages (RM) and to investigate the association between MTHFR genotype variants and alloimmune activation, proportion of peripheral blood natural killer (pbNK) cells. Methods: A total of 39 patients with a history of two or more unexplained miscarriages were recruited to this study. The controls were women who had a live birth without a history of RM (n=50). The proportion of pbNK cells was measured by flow cytometry. Plasma homocysteine levels and the incidence of the MTHFR variant of the RM and control groups were compared. The proportion of pbNK cells was compared to the MTHFR variants in the RM group. Results: No differences were found between the two groups' mean plasma homocysteine levels ($7.6{\pm}1.5{\mu}mol$/L vs. $7.1{\pm}2.1{\mu}mol$/L) or incidence of the MTHFR genotype variant (CC, 35% vs. 33%; CT, 40% vs. 53%; and TT, 25% vs. 14%). In the RM group, individuals with the TT variant ($7.7{\pm}1.1{\mu}mol$/L) had higher homocysteine levels than those with the CC and CT variants ($7.4{\pm}1.9{\mu}mol$/L and $7.4{\pm}1.2{\mu}mol$/L) and those with the CT variant ($19.2{\pm}8.1%$) had a higher proportion of CD3-/CD56+ pbNK cells than those with the CC and TT variants ($17.7{\pm}6.6%$ and $17.9{\pm}7.0%$), but the results of both comparisons were statistically insignificant. Conclusion: These preliminary results show no difference in plasma homocysteine levels between the RM and control groups or among MTHFR genotype variants in the RM group, which may suggest that the plasma homocysteine level is difficult to use as a predictive marker of RM in the Korean population. A study of a larger number of patients is needed.

A leaf methanolic extract of Wercklea insignis attenuates the lipopolysaccharide-induced inflammatory response by blocking the NF-κB signaling pathway in RAW 264.7 macrophages.

Park, Ji-Won,Kwon, Ok-Kyoung,Jang, Ha-young,Jeong, Hyeok,Oh, Sei-Ryang,Lee, Hyeong-Kyu,Han, Sang-Bae,Ahn, Kyung-Seop Kluwer Academic/Plenum Publishers 2012 INFLAMMATION Vol.35 No.1

<P>The biological activity of Wercklea insignis (WI) in inflammation and the underlying mechanisms of action of extracts of this plant are largely unknown. In the present study, we investigated the effects of a WI methanolic extract on lipopolysaccharide-stimulated inflammation in the mouse macrophage cell line, RAW 264.7. A WI methanolic extract significantly inhibited NO, PGE(2), IL-6, IL-1β, and TNF-α production in LPS-stimulated RAW 264.7 cells. Expression of iNOS, COX-2, IL-6, IL-1β, and TNF-α were suppressed by the extract at both the mRNA and protein levels in lipopolysaccharide (LPS)-stimulated cells. Additionally, the attenuation of inflammatory responses in RAW 264.7 cells by the WI extract was closely associated with suppression of phosphorylation of mitogen-activated protein kinase (MAPK) molecules, including ERK, JNK1/2, and p38 MAPK and translocation of the nuclear factor (NF)-κB p65 subunit into the nucleus. The effect of WI extract was investigated against carrageenan-induced paw edema in female (20-25 g). Our results collectively indicate that the WI extract inhibits LPS-induced inflammatory responses by blocking the NF-κB signaling pathway in macrophages, supporting use of the extract as a therapeutic anti-inflammatory treatment.</P>
