This paper examines how human capital and other economic variables, such as private investment, economic growth, government investment, inflation, and unemployment influence inequality in Indonesia's provinces. We apply panel data model with fixed effect estimation for the data of 34 provinces from the period 2013 to 2019. We develop a new index for human capital using the education index approach. The results show that human capital has a negative and significant effect on income inequality. An increase in human capital is related to an increase in knowledge and competence due to the longer average school year and expectations of the school year. Human capital has increased the possibility of a person being accepted into the job market and earning a higher income; hence, it lowers income inequality. We also find that inflation leads to a higher gap of income distribution. A further implication of this situation is that the rise in inflation causes an increase in low-income people, and as a consequence, makes their lives worse off. This paper will be beneficial for policy-makers for whom human capital, which is measured using an education index, is an important factor that significantly affects income inequality, in addition to other economic factors.

It is necessary to evaluate HMI inaspects of human factors in the design stage of MMIS(man machine interface system) and feedback the result of evaluation because operators performance is mainly influenced by the HMI. Therefore, the MMIS design should be reflected the operators psychological, behavioral and physiological characteristics in the interaction with human machine interface(HMI) in order to improve the safety and availability of the MMIS of a nuclear power plant(NPP) by reduction of human error. The development of human factors experimental evaluation techniques and integrated test facility(ITF) for the human factors evaluation become an important research field to resolve hi,am factors issues on the design of an advanced control room(ACR). We developed am ITF, which is aimed to experiment with the design of the ACR and the human machine interaction as it relates to the control of NPP. This paper presents the development of an ITF that consists of three rooms such as main test room(MTR), supporting test room(STR) and experiment control room(ECR). And, the ITF has a various facilities such as a human machine simulator(HMS), experimental measurement systems and data analysis and experiment evaluation supporting system(DAEXESS). The HMS consists of full-scope simulation model of Korean standard NPP and advanced HMI based on visual display nits (VDUS) such as touch color CRT, large scale display panel(LSDP), flat panel display unit and so on.

To investigate the possible isosteric replacement of imidazolidinone moiety in 4-phenyl-N-arylsulfonylimidazolidinone for broad and potent anticancer agents, a series of 4-phenyl-l(N)-arylsulfonylimidazolidinones 6a-k, imidazolidinethione analogs 7a-i, and imidazolidine oxime analogs 8a-c were prepared and evaluated for their in vitro anticancer activity against four human cancer cell lines (human lung A549, human colon COLO205, human leukemia K562, human ovary SK-OV-3). Among all the derivatives of N-arylsulfonylimidazolidinone 6a-k, compounds 6f and 6g showed the best inhibition comparable to doxorubicin against all cancer cell lines. Increasing the carbon chain on alkyl moieties of carbamates as shown in 6c-g did not alter the activity. The imidazolidinethione analogs 7a-i and imidazolidin-2-one oxime derivatives 8a-c did not possess any good activity. Therefore, imidazolidinone moiety is the best pharmacophore among the 4-phenyl-Narylsulfonylimidazolidinone derivatives.

About 70% -80% of the serious injury that occure in the chemical product small manufacturing industries is caused by human error. but technical development for analysis and inspection to preestimate and exclude such human error is still insufficient. Small - to - medium sited enterprises are economically vulnerable and technical foundations for safety management is week Under such circumstances development of easy to use computerized support programs that can be operated without the help of professioanals are keenly needed.

We examined effects of co-culture with human oviduct epithelial cells (HOEC) on the development of mouse and human embryos from early embryonic· stage to late morula or blastocyst stage (LM or B). In human, embryos were transferred and pregnancy rate was investigated. The HOEC, collected from surgically removed fallopian tube, were cultured in medium-199 supplemented with 20 % fetal cord serum (FCS). The HOEC were characterized by using immunocytochemical staining with anticytokeratin antibody and then used for cultures of mouse and human embryos. Results obtained from co-culture system were as follows. Development rate of mouse embryos was improved by co-culture system at late developmental stage (p<0.025). Human supernumerary embryos remained after transfer, unsuitable for freezing because of their poor quality, were co-cultured for 72hrs. Co-culture (78.79%) or conditioned medium (78.26%) system improved the developmemt rate, significantly, in comparision with control (11.11%)(p<0.00l). Co-cultured (85.71%) human zygotes for 24hrs showed the better development rate in comparision with control (50.00%) (p<0.01). When we transferred embryos cultured with the HOEC to patients, we obtained one pregnancy. Co-cultured human zygotes for 24hrs showed the better quality and viability for the replacement in comparision with control (p<0.01). In addition, improved pregnancy rate was obtained. Our results suggest that the co-culture system can rescue early degenerating embryos by improving early development and yield a resonable number of blastocyst for the appropriate replacement. The effect provided by cultured HOEC is not species specific for the development of embryos and it can be used to overcome in vitro blocks for the development. And also the co-culture system offers the possibility to freeze embryos at blastocyst stage which is more sucessful stage for the freezing. The HOEC monolayer may provide some stimulus via specific factor, which is unknown, to the development of embryos. Our results showed that the co-culture system with HOEC can be an alternative to conventional culture system.

User's sensibility has an important effect upon appreciating household electronic appliances and user's feeling of satisfaction with products has a good effect on the choice of product on purchasing those items. In this point of view, the human-oriented approach of product development system can be adopted as Human Sensibility Engineering. The target of changed development system is to define user's sensibility factors and to apply them to design and development. In this study, the human sensibility ergonomics approach and usability test have been applied to the development and evaluation of an electronic product model.

Human powered aircraft (HPA) is an airplane that uses only human power for its propulsion. It's development is completely different from conventional aircraft that use fuels as a power source. In the present study, special features for the development of HPA are discussed by studying the design requirements, weight estimation, aerodynamics and propulsion studies, power analysis, and mossion profile design. It is found that the development of the HPA is completely different from conventional aircraft. Mission profile is crucial to the successful flight of the sport HPA when the pilots are changed.

Mammography utilization is low in Iran compared with other countries. Here a cross-sectional survey design was used to investigate psycho-social and individual factors associated with mammography among 400 women asymptomatic of breast cancer. The study was carried out at the four outpatient clinics of Tehran during the period from July through October, 2009. We found that mammography screening was related to higher self-efficacy and women's occupation. Future tailored interventions on potential psycho-social determinants and specific demographic factors are critical in increasing mammography screening rates among Iranian women.
