The Architectural, Engineering and Construction (AEC) industry has a culture of long working hours that sometimes extend to weekends. As a result, construction employees find it challenging to achieve a balance between their work and personal lives. It is believed that there is rarely a clear separation between employees' work and personal life in the AEC industry. This paper suggests that in order to attract and retain a talented workforce, AEC organizations have to cater for the diverse needs of employees with regard to work-life balance. This paper presents the results of a survey of both professional and managerial employees' perspective on work-life conflict issues in private and public AEC organizations. Perspectives were found to differ, although not significantly, by employees' experience, leadership experience, age and gender. Furthermore, most survey respondents noted that their employers did not have a policy or program in place supporting work-life balance initiatives. Finally, although the AEC industry is making strides to improve work-life balance, the effort is lagging behind other industry sectors in providing policies and programs to promote work-life balance through flexible work hours and various other means.

염증반응(inflammation)은 발병, 진행, 악성 전이를 포함한 암의 진행과정(tumorigenesis)에서 중요한 역할을 수행하기 때문에 암 치료를 위한 전략으로 고려되고 있다. 감태(Ecklonia cava) 열수추출물(AEC)의 항암활성 동안 나타나는 항염증 반응을 연구하기 위하여, 비만세포(mast cells)의 분포, inducible nitric oxide synthase (iNOS)단백질, cyclooxygenase-2 (COX-2)단백질, nuclear factor (NF)-κB단백질, inflammasome 구성 단백질, inflammatory cytokines 발현의 변화는 AEC를 5주간 경구투여한 CT26 대장암을 내포하는 BALB/cKorl syngeneic 마우스에서 분석하였다. AEC를 처리한 후, 고형암의 무게와 조직 절편의 괴사 부위가 vehicle처리그룹에 비하여 감소하였다. 비만세포의 수는 vehicle처리그룹에 비하여 AEC처리그룹에서 증가했지만 COX-2와 iNOS의 발현은 AEC처리그룹에서 감소하였다. 또한, NF-κB, NLR family pyrin domain containing 3 (NLRP3), apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC)과 Caspase-1 (Cas-1)단백질의 발현도 유사한 감소가 관찰되었다. 더불어, tumor necrosis factor-α (TNF-α), interleukin-1α (IL-1α)와 interleukin-6 (IL-6)의 mRNA 발현이 vehicle처리그룹에 비하여 AEC처리그룹에서 감소하였다. 이러한 결과는 AEC가 CT26 고형암을 내포하는 BALB/cKorl syngeneic 마우스에서 항암활성은 염증반응과 밀접한 관련이 있음을 제시하고 있다.

A non-phosphorous program employing an alkyl epoxy carboxylate (AEC) has been successfully applied to petrochemical and other large industrial open recirculating cooling water systems. AEC is a patented non-phosphorous calcium carbonate scale inhibitor that has demonstrated better scale inhibition abilities than traditional organic phosphonates. In addition to its antiscalant properties, AEC inhibits carbon steel corrosion when used at high dosages. AEC can be combined with zinc to form a non-phosphorous program with very low levels of phosphate to provide an environmentally acceptable program. In actual applications, the total phosphate developed in the cooling system from cycling the makeup is below 1 ppm as $PO_4$. This level has complied with the highest standards of wastewater discharge limitations. The performance of two AEC/Zinc applications is reviewed. In both cases excellent corrosion and scale control were achieved with AEC/Zinc programs. One case history details the performance with a low hardness water (100 ppm calcium, as $CaCO_3$) operating at 8-10 cycles of concentration. The corrosive nature of the water and the long retention time of the system stressed both the corrosion and scale control capabilities of the program. The second case history demonstrates the performance of the program with a moderate hardness water (400-600 ppm calcium, as $CaCO_3$), but under harsh conditions of high temperature and low flow. The AEC/zinc combination has been found to be highly effective in controlling the corrosion of ferrous metals. AEC can provide good corrosion inhibition at high concentrations, while zinc is known to be an excellent cathodic inhibitor. The combination of the two inhibitors not only provides a synergistic blend that is effective over a wide range of operating conditions, but also is environmentally friendly.

ASEAN Economic Community (AEC) was established in 2015 from 10 countries to realize the ultimate (adopted in 1997), which aimed to transform ASEAN into a stable, prosperous, and highly competitive region with equitable economic development, reduced poverty, and socioeconomic disparities. The purpose of this paper is to examine the effect of knowledge level on the AEC of Vietnamese small and medium enterprises (SMEs) in the textile and apparel industry towards attitudes, readiness, and performance. This study uses convenience sampling to get questionnaires from 150 SMEs in Hanoi, Vietnam. Then, the paper applies SPSS-AMOS 24 to process data. The empirical results show that AEC's implementation only has a small impact on improving SME performance. However, SMEs have adequate knowledge, attitude, and readiness about AEC. The structural modeling findings indicate that the knowledge factor has an indirect effect on SMEs' performance. This finding is to provide new insight into the roles of attitude and readiness in the case of Vietnam. These factors are needed to mediate the effect of attitudes and readiness in the relationship between knowledge and business performance, a framework strategy of business organizations, and can be used as a conceptual model to improve SMEs' performance.

본 연구의 목적은 2015년 말 공식 출범한 아세안경제공동체(AEC)의 현황을 검토하고 AEC 출범 이후 베트남의 거시 경제적 상황에 대한 분석 및 시사점을 도출하기 위한 것이다. 이 글은 AEC가 통합의 과정에 있는 미완의 체제라는 점을 고려하여 AEC의 주요 목표 가운데 가장 실현 가능성이 있는 단일 시장 및 생산 기반 구축에 주목하였다. 최근 무역 지표에 따르면, 베트남은 전자 및 컴퓨터 관련 부품, 전화 및 관련 부품, 그리고 섬유 신발 분야에서 GVC 연결망의 중심에 위치해있어 제조 및 가공업 분야에서 생산성이 향상될 것으로 전망된다. AEC로 인한 기대와 함께 EU와의 FTA, 그리고 RCEP를 비롯하여 전세계 다양한 국가들과 양자 간 무역 협정을 체결하고 있기 때문에 향후 투자 거점지역으로서 베트남의 무역 의존도 및 FDI 유입은 더욱 높아질 것으로 전망된다. 하지만, 전체 수출액 가운데 외국투자기업의 수출 비중이 약 70%를 차지하고 있다는 점은 향후 베트남 경제의 불확실성을 암시한다. FDI 투자 유치는 베트남 국내기업의 경쟁력을 더욱 감소시킬 수 있다. 아직까지 베트남 국내 기업이 기술 혁신과 숙련된 인력을 확보하지 못한 현재의 상황에서 AEC를 통한 단일 시장 및 생산기반 구축은 베트남이 아세안 내 중간제조업 경쟁국가들(태국, 인도네시아, 필리핀)과의 경쟁에서 취약할 수밖에 없도록 만들 수 있기 때문이다. 따라서 베트남이 향후 지속가능한 발전을 유지해나가기 위해서는 외국투자기업으로부터의 성장 동력(momentum)을 베트남 자국 기업들의 발전으로 전환시키는 개혁 정책이 반드시 필요하다.
