This study is intended to analyze the conflict between the mother and the daughter revealed in the film, 'Daughter' and tries to suggest the therapeutic counseling techniques in the integrated perspective. It used a convergence in-depth psychological method. After deriving the unconscious conflicts of main characters through several film reviews, it was found that at the unconscious level true self and the false self, the ego ideal and the super ego, the individuation and the dependency are in mutual struggle. For Therapeutic counselling, the most important thing in the initial stage of the counselling is the experience of authenticity. The counsellor himself or herself should establish the right life values and stimulate the ego-ideal and strengthen the drive of true self. Also the counsellor should be aware of the dangers of the religious behavior as the transitional phenomenon. In the final stage, the counselor expects the client to continue to make efforts to change with the hope for the well-being.

In order to study electronic structures for locally disordered systems, we have developed a first-principle self-con-sistent-spin-polarized real space band method (TB-LMTO-R), which combines the tight-binding(TB) linear-muffin-tin orbital(LMTO) band rrethod and the recursion(R) rrethod. The TB-LMTO-R rrethod has been applied to fer-romagnetic bec Fe, hcp Co, and fcc Ni. With varying cluster sizes, recursion coefficients, and the order of the TB-Hamiltonian, we have calculated the local density of states(LDOS) and magnetic moments. It is found that the calculation with 5,000 atoms cluster, 40 continued fractions, and the second-order TB-Hamiltonian yields a conver¬gent result in agreement with those from the conventional LMTO. In this way, we have demonstrated a physical transparency of the TB-LMTO-R method as a real space description.

Drone based Magnetic Anomaly Detection measure a magnetic anomaly signal from the ferromagnetic target on the ground. We conduct a magnetic anomaly detection with 9 ferromagnetic targets on the ground. By removing the magnetic field measured in the absence of ferromagnetic targets from the experimental value, the magnetic anomaly signal is clearly measured at an altitude of 100 m. We analyze the signal characteristics by the ferromagnetic target through simulation using COMSOL multiphysics. The simulation results are within the GPS error range of the experimental results.

In this paper, we propose a multi-mode wireless power transfer (WPT) system with a dual loop structure. The proposed multi-mode WPT system consist of outer loop module which can operate at two different frequency bands including 6.78 MHz magnetic resonance WPT mode and 13.56 MHz near field communication (NFC) mode and inner loop module connected with outer loop which can operate at two different frequency bands including WPC mode and PMA mode based on inductive coupling standards. In order to be able to embed this system into smartphone battery back cover, the electrical designs are optimized and then the size was fixed $45{\times}90{\times}0.35mm3$ (including ferrite sheet) which is the same commercial smartphone. The proposed multi-mode WPT module can cover WPC and PMA mode based on inductive coupling. Moreover, it has more than 20 dB return loss characteristics at two different frequency bands including 6.78 MHz and 13.56 MHz, and shows more than 70 % transfer efficiency between resonant coils at 6.78 MHz in magnetic resonant charging environment.

The structural and magnetic properties of sputtered CoNbZr alloy films were investigated. In the as-deposited $Co_{87.0}$N $b_{8.5}$Z $r_{4.5}$ film deposited at 2 mTorr and 130 W, we observed the minimum coercivity of 1.75 Oe, the maximum resistivity of 3000 $\mu$Ω.cm and permeability of 1095 at 100 MHz. As the Ar pressure or the RF input power increased, the permeability of films at 100 MHz decreased and the coercivity increased because of the development of columnar structure and the formation of unstable amorphous phase. Permeability lower than 100 and coercivity of 60 Oe were observed in film deposited at 1 mTorr or 190 W due to the formation of crystalline phase. Magnetic anisotropy field of as-deposited films could be reduced by rotating field annealing for 120 minutes at 30$0^{\circ}C$. After the annealing, the anisotropy field (Hk) decreased from 1.43 Oe to 0.3 Oe and the permeability increased from 1095 to 1345 because defects in as-deposited films were eliminated by the annealing.aling.

Molecular simulation is an exceptionally useful method for predicting self-assembled structures in various macromolecular systems, enlightening the origins of many interesting molecular events such as protein folding, polymer micellization, and ordering of molten block copolymer. The length scales of those events ranges widely from sub-nanometer scale to micron-scale or to even larger, which is the main obstacle to simulate all the events in an ab initio principle. In order to detour this major obstacle in the molecular simulation approach, a molecular model can be rebuilt by sacrificing some unimportant molecular details, based on two different perspectives with respect to the resolution of model. These two perspectives are generally referred to as 'atomistic' and 'mesoscopit'. This paper reviews various simulation methods for macromolecular self-assembly in both atomistic and mesoscopic perspectives.

BaM thin films were prepared by using RF magnetron sputtering system at room temperature, and then successively annealed to crystallize at 850$\^{C}$ using RTA. The structure and magnetic properties of post-annealed BaM films have been investigated using XRD and VSM, respectively. The dependences of partial oxygen gas pressure (Po2) on the characteristics of BaM films were investigated. Although mixing of spinel and BaM phase only was identified in 0.5 mTorr oxygen partial pressure, BaM phase only was identified in the range from 1 to 3 mTorr oxygen partial pressure. The saturation magnetization and perpendicular coercivity of BaM thin films decreases with increase of Po2 in the range of Pot between 0.5 and 3 mTorr.

This paper suggests the novel light-weight signal processing algorithm for wireless sensor network applications which needs low computing complexity and power consumption. Exponential average method (EA) is utilized by real time, to process the magnetometer signal which is analyzed to understand the own physical characteristic in time domain. EA provides the robustness about noise, magnetic drift by temperature and interference, furthermore, causes low memory consumption and computing complexity for embedded processor. Hence, optimal parameter of proposal algorithm is extracted by statistical analysis. Using general and precision magnetometer, detection probability over 90% is obtained which restricted by 5% false alarm rate in simulation and using own developed magnetometer H/W, detection probability over 60~70% is obtained under 1~5% false alarm rate in simulation and experiment.

This study was conducted to investigate the effects of oral care behavior, oral health care self-efficacy, and social support on the subjective oral health level of the elderly. The data survey was conducted from September 17, 2019 to November 22, 2019 for the elderly living in Daejeon Metropolitan City and parts of Chungcheongnam-do, and the collected data were analyzed by 𝑥2-test, Pearson correlation analysis, and logistic regression analysis. As a result of the survey, subjective oral health level increased by 3.242 times when dentures were not used and 2.339 times when the number of brushings per day was 3 or more times. In addition, as the oral health care self-efficacy and social support increased 1.755 times and 1.192 times, respectively, the subjective oral health level also increased. Based on the above results, in order to improve the subjective oral health level of the elderly, opportunities for oral health education such as denture care methods and toothbrushing lessons should be expanded. In addition, there is a need to prepare policies to reinforce oral health care self-efficacy and social support.

This study aimed to confirm the effect of social support, self-efficacy, and job stress of clinical nurses on health promoting behaviors. The subjects of this study were 345 clinical nurses with more than 6 months of experience working at three general hospitals located in G city. Collected data were analyzed by descriptive statistics, t-test, ANOVA, Pearson correlation, and multiple regression analysis using SPSS 26.0 program. As a result, the prediction factors influencing health promoting behaviors were social support(𝛽=.36, p<.001), self-efficacy(𝛽=.35, p<.001), job stress(𝛽=-.09, p=.018), having breakfast four times a week or more(𝛽=.20, p<.001), and perceived health status is good(𝛽=.20, p=.001) or average(𝛽=.20, p<.001). And the explanatory power on health promoting behaviors from these variables was 49%(F=26.57, p<.001). Therefore, it is necessary to reflect programs and policies to improve the health promoting behaviors of clinical nurses.
