Immigration to a nation with a stronger anti-smoking environment has been hypothesized to make smoking less common. However, little is known about how environments influence risk of smoking across the lifecourse. Research suggested a linear decline in smoking over the lifecourse but these associations, in fact, might not be linear. This study assessed the possible nonlinear associations between age and smoking and examined how these associations differed by environment through comparing Koreans in Seoul, South Korea and Korean Americans in California, United States. Data were drawn from population based telephone surveys of Korean adults in Seoul (N=500) and California (N=2,830) from 2001-2002. Locally weighted scatterplot smoothing (lowess) was used to approximate the association between age and smoking with multivariable spline logistic regressions, including adjustment for confounds used to draw population inferences. Smoking differed across the lifecourse between Korean and Korean American men. The association between age and smoking peaked around 35 years among Korean and Korean American men. From 18 to 35 the probability of smoking was 57% higher (95%CI, 40 to 71) among Korean men versus 8% (95%CI, 3 to 19) higher among Korean American men. A similar difference in age after 35, from 40 to 57 years of age, was associated with a 2% (95%CI, 0 to 10) and 20% (95%CI, 16 to 25) lower probability of smoking among Korean and Korean American men. A nonlinear pattern was also observed among Korean American women. Social role transitions provide plausible explanations for the decline in smoking after 35. Investigators should be mindful of nonlinearities in age when attempting to understand tobacco use.

As a result of comparing and analyzing the related legislation of each nation, more superior legislative systems should be made to cope with a number of terrors effectively. And also it is required to devise some concrete regulations such as the following in superior legislative systems. First, because it is hard to collect information on terrorism and watch over suspects according to Communication Privacy Protection Law. More in-depth discussion into the issue of surveillance is needed for the protection of lives and property, although public concerns of privacy are a valid point of contention. Second, it is necessary to take complementary measures on immigration as surveillance, since the current Immigration Control Law has restrictions in many ways to hinder efforts to root out terrorists. Third, under the current law on financial activities, it is impossible to block influx of terror financing. Therefore it is necessary to come up with ways of making the punishment procedures. Fourth, considering that convicted terrorists get punished under the standard procedures and precedents, it is required to clearly differentiate between what the terror acts are and what terrorist groups are. Fifth, it is necessary to make use of the private security system to enhance the security system of national facilities.

Purpose: To assess the effectiveness of an 8-session health education program to promote the health of married immigrant women. Methods: A quasi-experimental research design was employed. The subjects included 36 female marriage immigrant women (17 in the experimental group and 19 in the control group) who agreed to participate in this study. The intervention involved 8 sessions with a partnership strategy and was led by Public Health Nurses and the researcher. Our analysis included descriptive statistics, Fisher's exact test, t-test, and Pearson correlation coefficients. Results: The results revealed significant mean differences in terms of self-efficacy between the two groups. The mean of their self-efficacy was higher in the experimental group than in the control group, whereas there no mean differences were detected between the two groups in terms of health knowledge and self-esteem. Additionally, the knowledge of the immigrant women was correlated with their self-efficacy. Conclusion: The 8-session health education program was found to have an effect on self-efficacy, even with the limitations to methodological rigors posed by the subject-specific conditions. In the future, health education materials written in the native language of such women will need to be develop. Additionally, repeated studies will be required that involve randomized controlled trials characterized by better methodological strength and strategies to enhance participants’ interests and motives.

Most countries have been promoted the legislative policy for the legal employment, causing a social conflicts by illegal immigrants in any countries. Despite the efforts to alleviate the illegal aliens, there are not nearly enough successful cases, and encounter a social problem about illegal stay worker. China is no exception. At present, the issue of China's foreign illegal employment is expected to be a social problem in the present and the future. However, the legislative policy against immigration control law and illegal foreign employment in China is very neglectful. There is a lack of adjusting rule of law on illegal foreign workers in China, and the remedy is also insufficient. It is necessary to secure a legal right for the protection of the Rights of illegal foreign workers based on the international norms. For this purpose, the illegal foreign workers related law should be enacted, and based on this, administration should be strengthened. The trend of major countries of illegal aliens is centered around an employer hiring strictly regulated. There is a need to have a strengthen regulation on the employer rather than the foreign workers in China. To this end, employer who hire illegal foreign workers should be required to receive considerable disadvantages such as penalties and fines, prison sentences, as well as various kinds of burdens and repatriation costs. It is necessary to run the voluntary repatriation(Freiwillige $R\ddot{u}ckehr$) program of illegal immigrants, and there is a need to take action for illegal immigrants who voluntary return home within a certain period are exempt from penalty. In conclusion, China must push ahead with a direction of positive policy in related ministries rather than sit on its hands on the wrong choice or a confusion of an employer and foreign workers with a policy on illegal foreign residents in limbo.

Today, an automatic and accurate processing using computer is essential because of the rapid increase of travelers. The determination of forged passports plays an important role in the immigration control system. Hence, as the preprocessing phase for the determination of forged passports, this paper proposes a novel method for the recognition of passports based on the fuzzy binarization and the fuzzy RBF network. First, for the extraction of individual codes for recognizing, this paper targets code sequence blocks including individual codes by applying Sobel masking, horizontal smearing and a contour tracking algorithm on the passport image. Then the proposed method binarizes the extracted blocks using fuzzy binarization based on the trapezoid type membership function. Then, as the last step, individual codes are recovered and extracted from the binarized areas by applying CDM masking and vertical smearing. This paper also proposes an enhanced fuzzy RBF network that adapts the enhanced fuzzy ART network for the middle layer. This network is applied to the recognition of individual codes. The results of the experiments for performance evaluation on the real passport images showed that the proposed method has the better performance compared with other approaches.

This study is a smart tourism research based on face recognition applied system that manages individual information of foreign tourists to smartphone. It is a way to authenticate by using face recognition, which is biometric information, as a technology applied to identification inquiry, immigration control, etc. and it is designed so that tourism companies can provide customized service to customers by applying algorism to smartphone. The smart tourism system based on face recognition is a system that prepares the reception service by sending the information to smartphone of tourist service company guide in real time after taking faces of foreign tourists who enter Korea for the first time with glasses attached to the camera. The smart tourism based on face recognition is personal information recognition technology, speech recognition technology, sensing technology, artificial intelligence personal information recognition technology, etc. Especially, artificial intelligence personal information recognition technology is a system that enables the tourism service company to implement the self-promotion function to commemorate the visit of foreign tourists and that enables tourists to participate in events and experience them directly. Since the application of smart tourism based on face recognition can utilize unique facial data and image features, it can be beneficially utilized for service companies that require accurate user authentication and service companies that prioritize security. However, in terms of sharing information by government organizations and private companies, preemptive measures such as the introduction of security systems should be taken.
