Electronic publishing has influenced, and in some ways changed, information seeking, reading patterns and citation behaviours. This study collected the Cited Half-Lives, the indicator implies the life-span of scholarly journals, from JCR Social Science edition the before and after of the prevalence of electronic journals, and observed if there are some changes in these two periods. The analysis results of eight disciplines show that the average Cited Half-Lives increased in 2007 than in 1994 for seven disciplines except the demography. Especially in the four disciplines of economics, education, finance and sociology, the average Cited Half-Lives increased significantly. This results show that the concentration, researchers cite more recent articles and concentrate their citations on fewer ones, is lightening and the dispersion of citations is actually increasing. With the online availability of articles and journals the old online materials can be often accessed, used and cited more frequently, the more growth potential of Cited Half-Lives are made in a digital environment. Further research needs to investigate if the phenomenon will become more obvious in various disciplines after a few years.

Rapid aging of the population affects population structure and population aging. Consequently, developed countries have focused on population aging as a major issue in regards to pension sustainability finances as well as health and the elderly welfare system. Mortality projections that result from population structure changes and population aging are increasingly important. This paper compares six mortality models using KOSTAT's life table from 1970 to 2016. The models are rooted in the Lee-Carter (LC) model (Lee and Carter, Journal of the American Statistical Association, 87, 659-671, 1992) and have been modified and improved on the assumptions of the LC model. We examined the improvement process and the check assumption by models in order to find a suitable mortality model for Korea. Korea shows rapid aging and declined mortality rate by age; therefore, it is desirable to estimate and predict mortality from LL&LC-ER models by combining LC-ER, LL, and LC-ER models that reflect the phenomena and modify age-specific mortality patterns without major changes in expected life expectancy.

This study examined the significance of the crew's professional consciousness and sought to clarify the differences in the professional consciousness of crew by considering biographical characteristics of the crew and onboard working situations, which were expected to influence the professional consciousness of crew. The empirical analysis showed the crew's individual characteristics such as age, marital status, position in ship organization and nationality significantly influenced professional consciousness. The comparison in the differences of professional consciousness level among crew's nationalities showed that the professional consciousness of Filipino crew was the highest, and in the descending order of Indonesia, Myanmar, Chinese, and South Korea. The analysis results of other variables of on-board working characteristics showed that as crew's satisfaction of welfare increased, crew's professional consciousness increased, whereas the feeling of isolation from home and society had a statistically significant negative (-) impact on crew's professional consciousness. Furthermore, the analysis of multinational crew manning characteristics stated that cross-cultural acceptance did not have a statistically significant impact on the crew's professional consciousness, while cross-cultural adaptability had a statistically significant impact. This study emphasize the importance of the crew's professional consciousness and suggest how to enhance it, which allows crew to continue their career with the charm and pride of their profession.

Background: Retinoblastoma is a rare type of cancer that usually develops in early childhood. If left untreated it can cause blindness and even death. The aim of this study is to determine sociodemographic and clinical features of retinoblastoma patients and also to determine the treatment pattern and outcome in Malaysia. Materials and Methods: Data for this study were retrieved from the Retinoblastoma Registry of the National Eye Database (NED) in Malaysia. Hospital Kuala Lumpur, Hospital Umum Kuching, Sarawak and Hospital Queen Elizabeth, Kota Kinabalu were the major source data providers for this study. Data collected in the registry cover demography, clinical presentation, modes of treatment, outcomes and complications. Results: The study group consisted of 119 patients (162 eyes) diagnosed with retinoblastoma between 2004 and 2012. There were 68 male (57.1%) and 51 (42.9%) female. The median age at presentation was 22 months. A majority of patients were Malays (54.6%), followed by Chinese (18, 5%), Indians (8.4%), and indigenous races (15.9%). Seventy six (63.8%) patients had unilateral involvement whereas 43 patients had bilateral disease (36.1%). It was found that most children presented with leukocoria (110 patients), followed by strabismus (19), and protopsis (12). Among the 76 with unilateral involvement (76 eyes), enucleation was performed for a majority (79%). More than half of these patients had extraocular extension. Of the 40 who received chemotherapy, 95% were given drugs systemically. Furthermore, in 43 patients with bilateral involvement (86 eyes), 35 (41%) eyes were enucleated and 17 (49%) showed extraocular extension. Seventy-two percent of these patients received systemic chemotherapy. The patients were followed up 1 year after diagnosis, whereby 66 were found to be alive and 4 dead. Sixteen patients defaulted treatment and were lost to follow-up, whereas follow-up data were not available in 33 patients. Conclusions: Patients with retinoblastoma in this middle-income Asian setting are presenting at late stages. As a result, a high proportion of patients warrant aggressive management such as enucleation. We also showed that a high number of patients default follow-up. Therefore, reduction in refusal or delay to initial treatment, and follow-up should be emphasized in order to improve the survival rates of retinoblastoma in this part of the world.

Purpose: This study was undertaken to compare perceived stress and coping patterns, and their effects on depression between cancer patients and healthy adults. Methods: A descriptive design was used with 278 subjects, consisting of 139 cancer patients and 139 health adults, living in an urban area. All participants completed the following prerequisites; Stress Visual Analog Scale, Ways of Coping Checklist (W.C.C.L), Depression Index (CES-D), and Demography and Disease Data Questionnaire. Results: Perceived stress and depression were significantly higher, while wishful thinking was lower among cancer patients than healthy adults, after adjusting for education and family income which were not homogeneous between the groups. Among cancer patients, 20.2% of depression was mainly due to seeking support (10.7%), perceived stress and education, while 30.7% of depression in healthy adults was due to perceived stress, problem solving, and seeking support. Conclusion: These findings suggest that interventions to manage depression in cancer patients should include strategies to best foster positive coping patterns and reduce perceived stress.

Purpose : Congenital urinary tract anomaly is the most common anomaly in the childhood and progress to chronic renal failure and growth retardation. Therefore, early diagnosis arid treatment of urinary tract anomaly are important. Method : We reviewed medical records of 124 patients who had urinary tract anomalies on radiologic studies from Jan. 1986 to Dec. 1996. We analyzed demography and clinical characteristics of urinary tract anomalies. Results : 1) The age distributions were as follows ; 61 cases of 124 patients (49%) were under 1 year, 11 cases (8.8%) from 1 to 3 years, 20 cases (16%) from 4 to 6 years, 10 cases (8%) from 7 to 9 years, 9 cases (7.2%) from 10 to 12 years, 10 cases (8%) from 13 to 15 years, and 3 cases (2.4%) from 16 to 18 years. 2) Chief complaints in patients with urinary tract anomalies were fever, flank pain, prenatally diagnosed hydronephrosis, abdominal mass, dysuria and hematuria. 3) Of 124 patients, 68 cases(54.8%) were combined with urinary tract infection, and main causative organism was E.coli, and the most frequently associated anomaly was vesicoureteral reflux. 4) Most of the urinary tract anomalies were VUR, UPJ obstruction, congenital hydronephrosis and double ureter in order of sequence. 5) Whereas the frequency of simple urinary tract anomaly was 87.9%, that of complex anomaly was 12%. 6) Operative corrections were needed in 47 cases and 7 cases were progressed to renal insufficiency. Conclusion : We emphasize that early detection of urinary tract anomaly, appropriate treatment and regular follow-up are needed.

Background: Globally, the overall incidence of cancer is increasing as a result of ageing populations and changing lifestyles. Cancer is one of the leading causes of death, especially in the developed nations. Cancers affecting the young population are generally considered uncommon. This study assessed the demography and trends of cancers of the young in Brunei Darussalam, a small and developing Southeast Asia nation. Materials and Methods: All patients diagnosed with cancers between 2000 and 2012 were identified from the cancer registry maintained by the State Histopathology Laboratory. Cancers of the young was defined as any cancers diagnosed under the age of 40 years. Demographic data and the type of cancers were collected and analysed using SPSS Statistics 17.0. Results: Among the 6,460 patients diagnosed with cancer over the study period, 18.7% (n=1,205) were categorized as young with an overall decline in the proportion from 26.6% in 2000 to 18.8% in 2012 (p<0.001 for trend). Among all cancers of the young, the most common systems affected were gynecological (24.1%), hematological/lymphatic (15.8%), subcutaneous/dermatological/ musculoskeletal (10.5%), breast (10.5%) and gastrointestinal (9.9%). Overall, among the different systems, neurological (54.9%) had the highest proportion of cancers of the young followed by gynecological/reproductive (30.6%), hematological/lymphatic (39.9%), endocrine (38.7%), subcutaneous/dermatological/ musculoskeletal (22.3%) and the head and neck region (20.1%). There was a female predominance (66.9%) and the incidence was significantly higher among the Malays (20.1%) and expatriates (25.1%) groups compared to the Chinese (10.7%) and indigenous (16.8%) groups (p<0.001 for trend). Conclusions: Cancers of the young (<40 years) accounted for almost a fifth of all cancers in Brunei Darussalam with certain organ systems more strongly affected. There was a female preponderance in all racial groups. Over the years, there has been a decline in the overall proportion of cancers of the young. Selective screening programs should nevertheless be considered.
