  • This paper describes an electronic compass using micromachined X- and Y-axis micro fluxgate sensors which were perpendicularly aligned each other to measure X- and Y-axis magnetic fields respectively. The fluxgate sensor was composed of rectangular-ring shaped magnetic core and solenoid excitation(49 turns) and pick-up(46 turns) coils. Excitation and pick-up coil patterns which were formed opposite to each other wound the magnetic core alternatively to improve the sensitivity and to excite the magnetic core in an optimal condition with reduced excitation current. The magnetic core has DC effective permeability of ~1000 and coercive field of ~0.1 Oe. The magnetic core is easily saturated due to the low coercive field and closed magnetic path for the excitation field. To decrease the difference of induced second harmonic voltages from X- and Y-axis, excitation condition of 2.8 $V_{P-P}$ and 1.2 MHz square wave was selected. Excellent linear response over the range of -100 $\mu$T to +100 $\mu$T was obtained with 210 V/T sensitivity. The size of each micro fluxgate sensor excluding pad region was about 2.6${\times}$1.7 $mm^2$ and the power consumption was estimated to be 14 mW.W.

  • Objectives : The aim of this study was to investigate whether and how the symptoms of adult attention deficit hyperactivity disorder (ADHD) affect the stress and depressive symptoms in Korean soldiers. Methods : Data were collected on 131 subjects through self-report using the Korean Adult Attention-Deficit/Hyperactivity Disorder Scale (K-AADHDS), Center for Epidemiological Studies Depression Scale (CES-D), Korean Wender Utah Rating Scale (K-WURS), and the Brief Encounter Psychosocial Instrument (BEPSI-K). Student t-tests, Pearson Correlation, Logistic regression, and Path analysis were performed. Results : The scores related to adult ADHD symptoms on the K-AADHDS and K-WURS were correlated with stress scores on the BEPSI-K (r=0.529, p<0.001 and r=0.484, p<0.001) and with depressive symptoms on the CES-D (r=0.686, p<0.001 and r=0.628, p<0.001). Scores related to adult ADHD on the K-AADHDS were the most significant risk factors for stress (O.R=1.198, 95% CI=1.104-1.299), and depressive symptoms (O.R=1.306, p95% CI=1.112-1.534). Path analysis on depressive symptoms showed that adult ADHD symptoms affected stress and depressive symptoms. Conclusion : The results suggest that it may be important to consider the evaluation and treatment of adult ADHD in soldiers. Prospective studies with larger numbers of subjects are warranted to further explore the relevance of the present results.

  • Electromagnetic (EM) waves used to send signals under seawater are normally restricted to low frequencies (f) because of sudden exponential increases of attenuation (𝛼) at higher f. The mathematics of EM wave propagation in seawater demonstrate dependence on relative permeability (𝜇r), relative permittivity (𝜀r), conductivity (𝜎), and f of transmission. Estimation of 𝜀r and 𝜎 based on the W. Ellison interpolation model was performed for averaged real-time data of temperature (T) and salinity (S) from 1955 to 2012 for all oceans with 41 088 latitude/longitude points and 101 depth points up to 5500 m. Estimation of parameters such as real and imaginary parts of 𝜀r, 𝜀r', 𝜀r", 𝜎, loss tangent (tan 𝛿), propagation velocity (Vp), phase constant (𝛽), and α contributes to absorption loss (La) for seawater channels carried out by using normal distribution fit in the 3 GHz-40 GHz f range. We also estimated total path loss (LPL) in seawater for given transmission power Pt and antenna (dipole) gain. MATLAB is the simulation tool used for analysis.

  • This study was a clinical Quasi-experiment to examine the effects of the range of motion exercise on powerlessness and life satisfaction among the E-Institutionalized elderly in Pusan. The purpose was to test the effect of the range of motion exercises on powerlessness and life satis-faction, and to examine the correlation between powerlessness and life satisfaction. The subjects for this study were 54 elderly people, both were over 60 and residing at I-Institution in Pusan. The research samples of 54 elderly were divided into an experimental and control group by matching randomized assignment. The instruments for this study were the Assessment Tool of Powerlessness in the elderly developed by Miller, Life satisfaction developed by Yoon Jin, and the Active-Passive Range of Motion Exercise Program which was developed and utilized by Shin, Jae-Shin. The data were collected from December 15, 1990 to November 1991. The paired t-test, t-test and ANCOVA were used to test hypothesis I and II, related to the Effect of the Range of Motion Exercises to powerlessness and life satisfaction. To identify the relationship of the range of motion exercises to powerlessness and life satisfaction, path analysis was done through multiple regression. The interrelationship of the variables was analyzed using t-test paired t-test. The results of the three hypothesis can be summarized as follows : 1. Hypothesis I -the experimental group which participated in the Range of Motion Exercise gets lower powerlessness score than that of the control group-was accepted by t-test (t = -3.40, p = .001) but not accepted by ANCOVA (F = .1, p =.96). 2. Hypothesis II - the experimental group which participated in the Range of Motion Exercise gets a higher Life Satisfaction Score than that of the control group-was not supported by t-test(t = 1.01, p = .316) but was accepted by ANCOVA (F = 4.39, p = .006). 3. Hypothesis III - if the powerlessness Score becomes higher, the Life Satisfaction Score will be-come lower - was accepted by Pearson Correlation Coefficient (pre-exercise : r : -.34, p=.006), (post exercise : r = -.06, p=.32) . The relation-ship between the score of powerlessness and life satisfaction was negatively correlated. The results obtained clearly showed that the effects of the range of motion exercises on powerlessness and life satisfaction are beneficial to the elderly The relation between the scores of powerlessness and life satisfaction was negatively correlated and the range of motion exercise had a direct influence to powerlessness. Therefore, it is concluded that the relationship between powerlessness and life satis-faction was not a causal one. Also it is concluded that the range of motion exercises can be applied as a nursing intervention to reduce powerlessness and to improve life satisfaction in the elderly.

  • In an attempt to cope with widespread, dynamic, and accelerating changes in both internal and external business environments, companies often utilize information technologies such as SCM(Supply Chain Management). To date, SCM research has mainly focused on the effects of dynamic factors on SCM success and emphasized adoption strategies and critical success factors. Consequently, the effects of more static factors such as interdependency between SCM partners have been largely ignored. The purpose of this study, therefore, is to examine the effects of both dynamic and static factors on SCM performance by controlling for information quality and partnership quality. The five factors examined in this study include innovative ness, mutual dependency, quality of information, partnership quality, and SCM performance. All factors were examined from the perspective of part suppliers, except the mutual dependency which was examined from two aspects: supplier's dependency on customer and customer's dependency on supplier. Data was collected through five hundred survey questionnaires distributed to the part supplier companies that have implemented SCM systems for at least one year. As a result, a total of 170 valid responses were obtained. A structural equation research model was fitted using SAS 9.1.3 and SMART-PLS 2.0. The results of this study can be summarized as follows. First, innovativeness positively affected SCM information quality. SCM partnership quality, and ultimately SCM performance. The path coefficient between innovativeness and information quality was 0.387, with a t-value of 3.528. Innovativeness also had a positively direct effect on partnership quality. The path coefficient was 0.351 with a t-value of 3.366. The total effect of innovativeness on partnership quality was significant, although its indirect effect on partnership quality by altering information quality was negligible. The total indirect effect of innovativeness on SCM performance by affecting information quality and partnership quality was significant with a p-value of 0.014. Innovativeness played an important role in determining SCM performance. Second, mutual dependency showed no significant effect on SCM information quality. This result contradicts the earlier assertion that the more dependent two companies are, the more accurate and timely the information they exchange ought to be. This study showed that this may not be the case; a partner may provide information of poor quality even when it is strongly dependent on the other. Mutual dependency showed significant effect on partnership quality. However, when the mutual dependency perceived by suppliers was divided into two parts, one being a supplier's dependency on its customer company and the other being a customer's dependency on the supplier, the latter showed a significant impact on the perceived SCM partnership quality. This result indicates that a customer company can hardly improve the partnership quality perceived by suppliers by making them more dependent. It improves only when the suppliers perceive that their partners, typically having more bargaining power, are more dependent on them. The overall effect of mutual dependency of any kind on SCM performance, however, was not significant. Although mutual dependency has been mentioned as an important static factor influencing almost every aspect of cooperation on a supply chain, its influences may not be as significant as it was initially perceived to be. Third, the correlation between information quality and partnership quality was 0.448 with a p-value of less than 0.001. Information quality had a path coefficient of 0.256 to partnership quality with a t-value of 2.940. The quality of information exchanged between partners may have an impact on their partnership quality. Fourth, information quality also had a significant impact on SCM performance with a path coefficient of 0.325 with a t-value of 3.611. In this study, SCM performance was divided into four categories: product quality, cost saving, service quality, and order fulfillment. Information quality has Significant impacts on product quality, cost saving and service quality, but not on order fulfillment. Fifth, partnership quality, as expected, had a significant impact on SCM performance. The path coefficient was 0.403 with a t-value of 3.539. Partnership quality, like information quality, had positive impacts on product quality, cost saving and service quality, but showed no impact on order fulfillment. It seemed that order fulfillment is the hardest category of performance that SCM can satisfy. One major limitation of this study is that it surveyed only the suppliers. To better understand the dual aspects of SCM, it is important to survey both suppliers and the assemblers, especially in pairs. This research, to our best knowledge, was the first attempt to study the level of dependency between the two groups by measuring the dual aspects of SCM and studying mutual dependency from the categories of suppliers and assemblers each.. In the future, a more comprehensive and precise measurement of SCM characteristics needs to be achieved by examining from both the supplier's and assembler's perspectives.

  • Internet of Things (IoT) is a relatively new concept that has gained immense popularity in a short period of time due to its wide applicability in making human life more convenient and automated. As an illustration: the development of smart homes, smart cities, etc. However, it is also accompanied by a substantial number of risks and flaws. IoT makes use of low-powered devices, so secure, less time-consuming and energy-intensive transmission (routing) of messages due to the limited availability of energy is one of the many and most significant concerns for IoT developers. The following paper presents a trust-based routing scenario for the Internet of Things (IoT) that exploits the past transmission record from the cupcarbon simulator's log files. Artificial Neural Network is used to quantify knowledge of trust, calculate the value of trust, and share this information with other network devices. As a human behavioural pattern, trust provides a superior method for making routing decisions. If there is a tie in the trust values and no other path is available, the remaining battery power is used to break the tie and make a forwarding decision; this is also seen as a more efficient use of the available resources. The proposed algorithm is observed to have superior energy consumption and routing decisions compared to conventional routing algorithms, and it improves the communication pattern.
