In this article, we investigate the transitivity and chain transitivity on multi-valued dynamical systems. For compact-valued continuous dynamics, we prove that the notion of transitivity is expressed by the notions of the shadowing property and chain transitivity under locally maximal condition.

Presently there is an increasing demand for home health care services due to changes in the demographic structure as a result of an increasing elderly population, socio-economic improvements, and changes in the family structure, as well as the growing number of people with degenerative diseases. In addition to these reasons, rising medical costs and there a shortage of patient beds space in the hospital, particularly since introduction of national medical insurance. There has been an increasing demand for health care health care services. This study was done to identify the basic data for home health care management. It focused on developing client selection criteria, assessment tools, and recording methods. This was accomplished by the researchers visiting the patients in their homes. The research process included preparation investigation, tool development, training of the project researcher, and visiting the clients in their homes. The research tools are as follows : 1. Record development : a) The selection criteria tool for home health care of postpartum women was a structured tool and consisted of four parts. b) The structured assessment tool consisted of a general items, obstetric history, past medical history, methods of feeding, medications taken before admission, laboratory test results, discharge instructions, discharge medications, family tree, economic status, environmental status, a map, health assessment of postpartum women and their newborns. c) The visit note I consisted of the frequency of visits. Visit note II consisted of the date ; nursing problems ; nursing process including the initial assessment ; nursing goal ; visit plan ; postpartum women and their neonate health status, diagnosis, goal, implementation, evaluation, summary, next plan, for visit revision. d) Problem note consisted of the date, problem numbers, nursing diagnosis, problem appearance date problem resolution date. The research results are as follows : 1. Nursing problems : The nursing problems of the postpartum women and their neonates were evaluated by the number of nursing diagnoses and the change in the pattern of nursing diagnosis related to the number of visits. a) Nursing diagnosis The nursing diagnosis was classified according to physical function, psychosocial function, family system maintained function. b) The changes of nursing diagnosis related to the number of visits. As the type of nursing diagnosis changed related to the number of visits the number of nursing diagnoses decreased. 2. Contents of home health care : The content was categorized according to assessment, direct care, counseling, education, family care, reporting to with the attending doctor. The recommendations based on the research results are as follows : 1. Tool development Replication of this study is needed to test the validity of the assessment tools used. 2. Home visit a) Home health care nurses should be licensed and qualified. A referral form from the attending doctor is needed for legal protection of nurses. b) The first home visit need to be within 24 hours of discharge from the hospital to decrease the anxiety of frightened postpartum women. c) When the changes occur in the newborn's status, home health care nurses should consult a pediatrician. Communication within the home healthcare team is essential and needs to consistent and done smoothly. 3. Home health care A Study is required to develop protocols for education of staff and for operation of all aspects of this program.

The 1,3-bis(4-aminoaryl)squaraines showed color, change behavior, they were found to undergo reduction with sodium borohydride in solution to give colorless leuco compounds, which oxidized readily in air back to the colored squaraine dye. We have shown that initial observations indicated that the derivatives synthesized gave new donor-acceptor chromophores. It is also interesting to note than the oxidation of the leuco squaraines did initially produce a species absorbing about 630-680 wavelengths. The 1,3-squaraines have found many uses as near-infrared absorbers, laser dyes and photoconductive materials. Furthermore their color-change redox behavior has potential in the area of peroxidase-based bioassaysas oxidation sensitive indicator systems were investigated.

This paper presents two cases of Science and Technology Parks (STPs), from Malaysia and India, that are driven by business organisations in partnership with governments. The need to locate the STP near to a university or a research institute has been considered crucial to attract firms to the STP - but in this paper, we illustrate the efforts to develop a locally relevant STP through the cases of Pahang Bio Science in Malaysia and the ICICI Knowledge Park (now known as IKP) in Hyderabad India. These two developments are anchored by business organisations that are playing a pivotal role in their development. The government plays a supporting role in terms of policy and supplying certain complementary resources. In addition, we note that the government support also provides legitimacy for the business organisation developing the STP. In the case of the Malaysian STP, we note the approach is towards inclusive development by developing linkages to local communities, and in the case of the Indian STP, one can see the development of the STP in a dynamic way changing according to the needs of the sector. Especially interesting is the foresight by the nodal business organisations in developing the STPs.

Vietnamese scholars contend that they have developed Southeast Asian studies viewing Southeast Asia as both a geographical entity with a long history and cultural tradition and a strategic region for modern development. This study has traced the construction of Southeast Asian studies as an academic discipline in Vietnam through the studies and arguments of Vietnamese scholars. It has put primary focus on the institutionalization of Southeast Asian studies, taking note of the assessment and perceptions of Vietnamese scholars. It also looked into the construction and limitations of Southeast Asian studies in Vietnam, which advocates Southeast Asian Studies as interdisciplinary area studies, with stressing of the origin of indigenous studies. The major contents of this study include: First, a historic overview of the institutionalization of Southeast Asian studies centering on research institutions of Southeast Asian studies in Vietnam, Second, the perceptions of Southeast Asian studies inside Vietnam and the inside evaluation of the effort to indigenize Southeast Asian studies. This study took note of Vietnamese scholars' perceptions and assessment of Southeast Asian studies performed by outsiders, primarily by Western scholars; the perceptions and evaluation of Southeast Asian studies conducted by Southeast Asian insiders; and the perceptions and evaluation of the origin of Southeast Asian studies indigenous to Vietnam. Last, it examined the construction and limitations of Southeast Asian studies in Vietnam, which advocates the studies as interdisciplinary regional studies.

Bimaxillary transverse width discrepancies are commonly encountered among patients with dentofacial deformities. Skeletal discrepancies should be diagnosed and managed appropriately with possible surgical corrections. Transverse width deficiencies can present in varieties of combinations involving the maxilla and mandible. We observed that in a significant proportion of cases, the maxilla is normal, and the mandible showed deficiency in the transverse dimension after pre-surgical orthodontics. We designed novel osteotomy techniques to enhance mandibular transverse width correction, as well as simultaneous genioplasty. Chin repositioning along any plane is applicable concomitant with mandibular midline arch widening. When there is a requirement for larger widening, gonial angle reduction may be necessary. This technical note focuses on key points in management of patients with transversely deficient mandible and the factors affecting the outcome and stability. Further research on the maximum amount of stable widening will be conducted. We believe that developing evidence-based additional modifications to existing conventional surgical procedures can aid precise correction of complex dentofacial deformities.

In reality, there are numerous [Note: I advise to change the tone to being more certain, as opposed to offering a possibility. You need to emphasize the seriousness of the conditions that your study wants to talk about] non-tariff trade barriers under free trade agreements, with various stakeholders having different trade-off interests. This study focuses on the rules of origin verification and considers cases in which domestic firms, foreign firms, and domestic consumer groups compete politically for their rent protection in the domestic market. As in Gwande et al. (2006), cross-border lobbies are considered possible wherein foreign firms also lobby the government to influence the decision-making process of how stringently to verify the rules of origin. [Note: Starting here, switch to past tense because a: study intentions above can be in present tense, b: study procedures should be in past tense] In this study, we assumed that all stakeholders form interest groups and present political contributions to the government based on their interests. The stringency of the rules of origin verification was then determined through this political process, and we compared this to a socially optimal one in the analysis. It was found that the verification was less stringent when there was cross-border lobbying than the socially optimal one.

With the rising attention dedicated to research ethics, the responsibility of researchers to comply with research ethics is also highlighted. Among a number of research ethics obligations that researchers should abide by, an institutional review board (IRB) review is the most essential step to be taken before launching research. As the health service research field grapples with human subjects, it closely aligns with IRB deliberation. However, it seems that researchers still do not fully understand their obligations of IRB reviews. Due to the nature of health services research, there are many cases that are exempt from IRB reviews, which often elicits confusion in the research field. On that note, we aim to explore the issues regarding IRB reviews that health service researchers need to know.
