The variation of marine accidents and ship's insurances is to be the measurement of assessment concerned effect of importing ISM Code because each kind of ship accident's expenses and compensation for the loss have an effect on the ship's insurance and P&I insurance. Therefore in this study, we had grasped the accomplishment of importing ISM Code, using analysis of the variation of marine accidents and ship's insurances in domestic shipping companies from one year ago to 8 years after importing ISM Code. As the result of analysis, compared with the period of a year before carrying out ISM Code, marine accidents were showed a decrease of about 14.4% at 8th year of importing ISM Code. Also, the insurance had tended downward every year.

Introduction: Geriatric depression is one of the significant mental health issues for older people. This descriptive study aimed to investigate the correlation between selected factors and depression among older people, living in homes for the aged in the western part of Thailand. Methods: 107 older people, living in two homes for the aged of the western part of Thailand were recruited to the study, using cluster sampling. Three questionnaires, including the Barthel Index Activity of Daily living (BADL), the Thai Geriatric Depression Scale (TGDS), and personal characteristics, perceived health status, chronic diseases, family relationship, and recent grief and loss experience were used. The quality of all questionnaires, especially the reliability of BADL, TGDS, and selected factors (e.g., health factors) were 0.95, 0.93, and 0.72 respectively. After finishing data collection, percentages, medians, and Spearman's rank correlation and Mann-Whitney U were used to analyze the data. Results and discussion: The results revealed that nearly half (41.1%) of older people suffered from depression. Furthermore, income, perceived health status, and Barthel ADL index were significantly negatively associated with depression at p<0.01; whereas, the number of chronic diseases was significantly positively associated with depression at p<0.05. Conclusion: results on the correlation may guide the practice in the future. For example, the officers or health care providers in homes for the aged should encourage older people to be independent, improve their perceived health status, increase health promoting behaviors to prevent or delay chronic illnesses, or increase older people incomes by promoting the appropriate occupation.

We report clinical, cytogenetic, and fluorescence in situ hybridization (FISH) studies of a patient with ring chromosome 9. She presented with failure to thrive, facial dysmorphysm and mild psychomotor development delay in the absence of major malformations. Peripheral blood karyotype of the patient was 46,XX,r(9)(p24q34). G-band analysis suggested no loss of material in the ring chromosomes. FISH analysis using the subtelomere-specific sequences on chromosome 9p and 9q, revealed 46,XX,r(9)(p24q34),ish r(9)(D9S913-,D9S325+). Failure to detect any hybridization of a probe for the subtelomeric sequences in the ring 9p terminal suggested that this ring arose from breakage in the distal short arm. The cytogenetic and FISH data in our case provided further evidence for the existence of a "complete ring" phenotype with incomplete subtelomeric sequences.

Cancer is one of the most challenging human diseases. Current clinical methods have limitations for early-stage cancer diagnosis and effective therapy. Moreover, current surgical methods to remove tumors are not precise enough and chemotherapy destroys normal tissues as well as malignant tumors, resulting in severe side effects such as hair loss, vomiting, diarrhea, and blood disorders. Recently, nanotechnology using nano-sized particles suggests advanced solutions to overcome the limitations. Various nanoparticles have been reported for more accurate diagnosis and minimized side effects. However, current nanoparticles still show limited targeting accuracy for cancer generally below 5% injection dosage. Therefore, herein we report a new nanoparticle inducing device(NID) to guide the nanoparticles externally by using both variable magnetic fields and blood flows. NID can be a promising approach to improve targeting accuracy for drug delivery using iron oxide nanoparticles.

We developed a multicast communication packet radio protocol using a time-sharing tablet system ("wireless token ring") to achieve the efficient exchange of files among packet radio terminals attached to swans. This paper provides an overview of the system and the protocol of the packet communications. The packet device forming the main part of the transceiver developed is the Texas Instruments CC2500. This device consists of one call-up channel and one data transmission channel and could improve error frame correction using FEC (forward error correction) with 34.8 kbps MSK and receiving power of at least -64 dBm (output 1 dBm at distance of 200 m using 3 dBi antenna). A time-sharing framework was determined for the wireless token ring using call sign ordinals to prevent transmission right loss. Tests using eight stations showed that resend requests with the ARQ (automatic repeat request) system are more frequent for a receiving power supply of -62 dBm or less. A wireless token ring system with fixed transmission times is more effective. This communication protocol is useful in cases in which frequency resources are limited; the energy consumed is not dependent on the transmission environment (preset transmission times); multiple terminals are concentrated in a small area; and information (position data and vital data) is shared among terminals under circumstances in which direct communication between a terminal and the center is not possible. The method allows epidemiological predictions of avian influenza infection routes based on vital data and relationships among individual birds based on the network topology recorded by individual terminals. This communication protocol is also expected to have applications in the formation of multiple in vivo micromachines or terminals that are inserted into living organisms.

In this paper, we derived the design equation and implemented the unequal Gysel power divider that is one external resistors using the ABCD parameters analysis. Conventional unequal Gysel divider is difficult to obtain the characteristics of isolation and return loss at between output ports because it can't select a theoretical value of external resistor. To solve those problems, we design the new unequal Gysel power divider with transmission lines and one external resistor that has the characteristics of conventional unequal Gysel divider. To validate this design method, we simulated and measured an 4: 1 unequal Gysel power divider at the center frequency 1 GHz. The measured performances agreed well with the simulation results.

This paper presents a realization of a peer-to-peer communication system for a UAV navigational monitoring using a commercial HSDPA(High Speed Download Packet Access) mobile communication device. The realized system consists of a communication server, an air data terminal and multiple ground monitoring devices, where the server transfers navigational data from a UAV to multiple monitoring devices in real-time with commercial HSDPA modem. Through ground and flight tests, data were obtained to observe the realized system. Test results show that, depending on communicational environment, about 300msec delay, congestion and packet-loss between air data terminal and ground monitoring devices. Nevertheless, through high-speed long range test on a ground vehicle and altitude test with a UAV flight, the feasibility of a UAV navigational monitoring system was observed.

Global navigation satellite system (GNSS) has a weakness of signal integrity caused by broadcasting type data transmitting direct to user from navigation satellite. Loss of GNSS signal integrity can make a catastrophic event in the operation of unmanned aerial system (UAS) because position decision is only depended on GNSS. So it is required to apply alternative method to reduce a risk and to guarantee a GNSS signal integrity for UAS operation. This paper addressed the reason of loosing GNSS signal integrity, the effectiveness of signal jamming/spoofing and GNSS application trend for UAS. Also suggested the flight safety enhancing method in case of GNSS signal jamming for UAS as technical and political approaches.

We have examined the development and conceptual definition of shamanism and divination through significant characteristics of various illnesses. However, the terrminology has been inconsistent and its real conceptual meaning is not well defined. Divination is a historically dominant religious practice which represents the core of Korean folk culture. Despite prevalent prejudice toward its primitive nature, we cannot deny its profound relationship to our unconscious, especially our reliance on its religious role whenever we face crisis or conflict. It is therefore appropriate to use the term divination in this context. Shamanism originated as humanity's oldest mode of communication with divine - a religion, The shaman is not a sorceress but a priestess, a healer, a spritual guide, a leader, a mystic, traditionally having a different significance from that of the contemporary diviner or "shaman". The traditional concept of illness has been profoundly altered to serve new functions: while the shamanistic view is based upon spiritual abduction, divination on the other hand invokes concepts of spiritual invasion phenomena such as spirit intrusion, taboo violations, soul loss, object instrusion, deviations from the appropriate spiritual path besiegement, and curess or predestination (the idea that the sufferer is born with his fate), We should therefore try to understand divination from a more holistic point of view, rather than attempting to fit it into the standrd medical illness. We must recognize divination as a phenomenon within our culture, since most people have a mixed conception of illness arising from a combination of divinational and modem concepts, Since divination's humanistic approach is ingrained in our people, to irresponsibly ignore the spiritual aspects of treatment would exert a negative influence on our culture, Especially now, while attraction is focused on Korean culture and its influence on every aspect of our livies, it is important for nurses to expand our horizons in order to create a way of nursing more suitable to Korean culture. Increased importance is now being given to the opinions of patients themselves about their own illness and health, so nurses should seek to understand how patients accept their illness and what particular kinds of help they expect to receive. Consequently, an understanding of traditional divinations will enable us to utilize these characteristics on the job in order to enhance nursing care.

In a PCB factory, there is a corrosive chemical substance supply system that can causes major leakage accidents. These accidents can give rise to shut down the factory and do residents damage that cause enormous loss of properties. To mitigate these risks, it is necessary to provide a chemical disaster prevention system. Moreover, after considering the situation and environment of the production site, it is of great importance to build an optimal chemical accident prevention system by reflecting risk reduction measures from the point of process design and by assessing quantitative risk based on reliability data. However, because there was no established database of the reliability about facilities and equipment that can be used in the domestic, the business site and consulting organization had being used the reliability data such as USA CCPS(Center for Chemical Process Safety). In these days, Korean institutes are studying on reliability data utilization method of quantitative risk assessment for preventing chemical accidents and domestic utilization algorithms and storage bed of reliability data. This study presents samples of reliability database about the chemical substance supply system that constructed from the history data such as failure, maintenance for 10 years at a PCB factory. Also, this work proposes the safety design criteria for supply facilities of corrosive chemical substance by assessing quantitative risk on the basis of the reliability data.
