Purpose: This was a correlation study to identify the relationship of spiritual well-being, hope on fatigue in cancer patients on chemotherapy. Methods: The subjects completed structured questionnaires: the 'Spiritual Well-being Scale', developed by Paloutzian & Ellison, 'Hope Scale', developed by Kim & Lee and 'Fatigue Scale', developed by Mendoza et al. Data were collected from 120 patientsat two general hospitals and were analyzed using t-test, ANOVA & Sheffe's test, Pearson's correlation coefficients and multiple stepwise regression. Results: Participants with higher fatigue had lower scores for hope (r=-.36, p<.001) and lower scores for spiritual well-being (r=-.23, p=.011). Participants with higher scores for hope had higher scores for spiritual well-being (r=.61, p<.001). The factors seen as contributing to fatigue were hope, financial burden of treatment, period of religious life, living with spouse, and reported pain. These variables explained 32.3% of the variance in fatigue. Hope with 13% was the most influential. Conclusion: The fatigue of the cancer patients on chemotherapy can be reduced if hope is improved, and hope can be improved if the spiritual well-being is improved. Therefore, we suggest developing a nursing intervention program that leads to improve hope and spiritual well-being of the cancer patients on chemotherapy for reducing fatigue.

This study investigated the effect of parental attachment on interpersonal competence and psychological well-being of college students. 625 college students completed self-administered questionnaires. Reliability test, ANOVA, Duncan ex-post analysis, and hierarchical regression analysis on data were used. Study results showed that parental attachement and interpersonal competence had significant effects on college students' psychological well-being. Results also depicted gender differences in the relationship of study variables; students' interpersonal competence demonstrated partial mediation effect in the relation of attachment with the same-sex parent and psychological well-being, while complete mediation effect in that of attachment with the opposite-sex parent and psychological well-being, These findings suggest that gender-conscious university policies to promote interpersonal competence among students are greatly needed to ensure psychological well-being of the student population.

Step-drawdown test has been generally conducted to evaluate productivity or efficiency of both aquifer and well. In general step-drawdown test, pumping with a low constant discharge rate is conducted in the first stage until the drawdown within the well stabilizes. And then the groundwater is pumped with a higher rate in the next step until the drawdown stabilizes once more. This process is repeated at least three times (steps), with the equal duration. In this paper we tried to review some critical problems related to the step-drawdown test, which were revealed in the process of field practices and analyses. The problems, referred in this paper are mainly associated with the incorrect conceptual approach for analysis and incomplete data collection in the field test.

Static stability is a decisive factor in the design of domes. Stability-related external factors, such as load and supports, are incorporated into structural vulnerability theory by the definition of a relative rate of joint well-formedness ($r_r$). Hence, the instability mechanism of domes can be revealed. To improve stability, an optimization model against instability, which takes the maximization of the lowest $r_r$ ($r_{r,min}$) as the objective and the discrete member sections as the variables, is established with constraints on the design requirements and steel consumption. Optimizations are performed on two real-life Kiewitt-6 model domes with a span of 23.4 m and rise of 11.7 m, which are initially constructed for shaking table collapse test. Well-formedness analyses and stability calculation (via arc-length method) of the models throughout the optimization history demonstrate that this proposed method can effectively enhance $r_{r,min}$ and optimize the static stability of shell-like structures. Additionally, seismic performance of the optimum models subjected to the same earthquake as in the shaking table test is checked. The supplemental simulations prove that the optimum models are superior to the original models under earthquake load as well.

An artificial recharge test aimed at investigating transport characteristics of the injected water plume in a fractured rock aquifer was conducted. The test used an injection well for injecting tap water whose temperature and electrical conductivity were different from the groundwater. Temporal and depth-wise variation of temperature and electrical conductivity was monitored in both the injection well and a nearby observation well. A highly permeable fracture zone acting as the major pathway of groundwater flow was distinctively revealed in the monitoring data. A finite element subsurface flow and transport simulator (FEFLOW) was used to investigate sensitivity of the transport process to associated aquifer parameters. Simulated results showed that aperture thickness of the fracture and the hydraulic gradient of groundwater highly affected spatio-temporal variation of temperature and electrical conductivity of the injected water plume. The study suggests that artificial recharge of colder water in a fractured rock aquifer could create a thermal plume persistent over a long period of time depending on hydro-thermal properties of the aquifer as well as the amount of injected water.

Purpose: The purpose of this study was to determine the effects of a happiness choice program based on reality therapy on subjective well-being and interpersonal relations in nursing students. Methods: A nonequivalent control group pre-posttest design was used. The participants were 45 nursing students, 22 in the experimental group, and 23 in the control group. They were from 2 different colleges of nursing located in 2 regions. The happiness choice program based on reality therapy was held 6 times over 6 weeks, taking 120 minutes per session. Nursing students' subjective well-being and interpersonal relations were measured. SPSS 18.0 using the ${\chi}^2$-test, t-test, and paired t-test were used in data analysis. Results: Nursing students in the experimental group showed significantly higher life satisfaction (t=3.81, p<.001), positive emotion (t=2.09, p=.042), and interpersonal relations (t=4.11, p<.001), while significantly lower negative emotion (t=-2.59, p=.013). Conclusion: The findings of this study suggest that a happiness choice program based on reality therapy could be a useful intervention for improving subjective well-being and interpersonal relations of nursing students.

Thermal humidity characteristics were considered theoretically and experimentally. A Simply well-fitted correlation of a saturated vapor pressure-temperature curve of water was introduced based on Antoine equation to make theoretical prediction of relative humidity according to temperature variation. Characteristics of dew point were also examined theoretically and its relation with temperature and humidity was evaluated. The exact mass of water vapor in a specified humidity and temperature condition was estimated to provide useful insight into the idea about how much amount of water corresponds to a specified humidity and temperature condition in a confined system. A simple but well-fitting model of dehumidification process was introduced to anticipate the trend of relative humidity level during GN2(gaseous nitrogen) purge process in a humidity chamber. Well-suitedness of this model was also verified by comparison with experimental data. The overall appearance and specification of two thermal humidity chambers were introduced which were used to perform various thermal humidity tests in order to yield useful data necessary to support validity of theoretical models.

Rapid loss in viability of neem (Azadirachta indica A. Juss.) seed is a major problem. Present effort was undertaken for developing a set pattern for assessing of viability and vigour in seed of various mother tree age of neem (Age I-06 years, Age II-15 years, Age III-25 years and Age IV->30 years old). Various viability test viz. triphenyle tetrazolium chloride test, electrical conductivity, excised embryo test, and germination test have been performed on seeds obtained from mother tree age classes. Inconsistency was observed with the TTC and EC test in germination of seed in laboratory as well as nursery. While various vigour tests viz. cold test, chemical stress test (methanol stress test), and accelerated ageing test alongwith ageing index, germination test (G%, MGT and GV) and various seedling growth parameters like seedling length (cm), number of leaves, collar diameter (cm), total biomass (g) alongwith mathematical indices i.e. vigour index, sturdiness quotient, volume index, quality index, root shoot ratio in nursery as well have been taken for study and showed better consistency. On the basis present study results of various viability and vigour test indicated that mother tree age class II performed better in comparison to others and it can be recommended for seed collection. Further it is also recommended that viability of neem seed may be assessed using various laboratory tests like excise embryo test and germination test (G%, MGT and GV) and vigour test may be taken preferably by cold germination test, chemical (methanol) stress test, accelerated ageing test in laboratory and germination alongwith various seedling growth parameters seedling length (cm), number of leaves, collar diameter (cm), total biomass (g) alongwith mathematical indices like Vigour Index, Sturdiness quotient, Volume Index, Quality index, root shoot ratio in nursery as discussed in this study.

This study examined the effects of hospice & palliative care education programs for nursing students, in terms of spiritual well-being and knowledge concerning advance directives. This is a quasi-experimental study of non-equivalent control groups, and includes a pre-test and post-test design. Data was collected between September to December 2018, enrolling third grade nursing college students attending a university in C city: 22 subjects in the experimental group and 27 subjects in the control group. The experimental group was provided the education as a regular subject, 2 hours a week for 7 weeks, for a total of 14 hours. Ed. Notes: I suggest you maintain any one unit for mentioning time. Hence, I changed 120 mins to 2 hours. Data were analyzed by X2 test, Fisher's exact, t-test, independent t-test, and paired t-test, using the SPSS 21.0 program. After attending the program, spiritual well-being showed a significant increase (t=2.80, p=0.009). However, there was no significant difference between groups in knowledge regarding advance directives (t=1.33, p=0.190). Our results indicate that the hospice & palliative care education program helps nursing students improve their score of spiritual well-being. We believe that these results contribute basic data for the future development of hospice-palliative care curriculum.
