The purpose of this study is to characterize the internal physical properties of fresh Korean ginsengs (Panax ginseng C.A. Meyer) through a magnetic resonance imaging (MRI) technique. Current external visual inspection cannot determine internal quality of ginsengs successfully. Relaxation time constants, T$_1$ and T$_2$*, were obtained from a series of MR images. Calculated Ti values were varied with different physiological states of ginseng tissues. Internal imaging information was obtained nondestructively from fresh ginsengs. One- and two-dimensional image analyses were performed. One-dimensional image analysis showed a potential of age identification of ginsengs rapidly. Internal quality of normal and abnormal ginsengs was evaluated using two-dimensional MR images. Various types of internal defects such as internal cavity and rotten spot were visualized clearly. The MRI technique had a feasibility to detect internal defects of fresh ginsengs effectively.

The purpose of this study was to develop and evaluate an attachment improvement program for families adopting an older child. The objectives and contents of this program reflected on the experiences of adopted parents and the characteristics of older-age adoptee children with attachment disruption. The program consisted of three components: parent-child relationship building, parenting skills enhancement for adopted parents, and negative emotions mediation for the older-age adoptees. The subjects of program were eight parent-child dyads. Differences between pre- and post-test data showed statistically significant improvements in the quality of parent-child relationships, communication levels with parents, and the parents' autonomic levels. There was also a reduction in the children's social problems. The implications of this study were discussed in terms of improving parent-child attachments in families adopting an older child.

This study was performed to establish the early pregnancy diagnosis with evaluation of size of embryonic vesicles and change of crown-rump length (CRL) by transrectal ultrasonography in the Korean black goats. Early pregnancy diagnosis was performed in the 114 goats from 19 to 35 days after coitus by transrectal 5.0 MHz transducer. Embryonic vesicles and CRL in the 142 goats from 19 to 42 days was measured to establish the correlation between gestational age and these parameters. The early pregnancy diagnosis achieved 80% accuracy after days 25 and 100% accuracy after days 28 after breeding. Diameters of embryonic vesicle and CRL were significantly increased with the gestational age. In these facts, early pregnancy diagnosis is possible on Days 25 after breeding and measurement of embryonic vesicles and CRL were useful to predict the gestational age in Korean black goat.

Purpose: The purpose of this study was to evaluate the nutritional status of elderly Korean women and to investigate related factors. Methods: A total of 100 elderly women attending a local elderly welfare center were recruited for study. Evaluation criteria included demographics, clinical status, nutritional status (using a mini-nutritional assessment), food intake, and nutritional bioparameters, including homocysteine, transferrin, prealbumin and lymphocyte levels, and their antioxidant power status. Results: Among the test group, 83% of the subjects were classified as undernourished, and they often had hyperlipidemia and a lower intake of fiber ($p$ <.05, respectively) and vegetables than normal subjects. In a correlation analysis, their nutritional status was associated with abdominal circumference, the Korean Geriatric Depression Scale score and the Enriched Social Support Inventory score. Nutritional bioparameters and antioxidant power were associated with age among undernourished subjects. Old age, the prevalence of hyperlipidemia, and poor social support significantly increased the risk of undernutrition. Poor social support, the prevalence of diabetes mellitus and depression significantly increased the risk of nutritional deficiency after controlling for age, educational and economic variables. Conclusion: More strategies to increase social support in the Korean female elderly population may improve their nutritional status.

Objectives : The purpose of this study is to evaluate the correlation between bone mineral density(BMD), age, weight, visual analog scale(VAS), menopausal rating scale(MRS), and to compare the difference between BMD, age, weight, VAS, MRS according to severity of the menopausal symptoms. Methods : The participants were 62 menopausal women diagnosed with osteoporosis who visited Cheonan Oriental Hospital, Daejeon University from December, 2011 to July, 2014. Age, weight, VAS, MRS were used as an evaluation tool. Results : 1. In all 62 cases of menopausal patients diagnosed with osteoporosis, the study found a statistically significant correlation between BMD and weight, while inverse correlation between BMD and MRS index. 2. Among menopausal patients with above 9 MRS index(group B), BMD and weight showed statistically significant correlation, while VAS and MRS index showed statistically significant inverse correlation. 3. Among group B, VAS were higher compared to control group(group A). Conclusions : This study showed that as patients with severer menopausal symptoms apt to show increased VAS and decreased BMD. Therefore, long-term follow-up in patients with menopausal syndrome is needed to improve the patients' quality of life.

In any reactor physics analysis, the instantaneous power distribution in the core can be calculated when the actual bundle-wise burnup distribution is known. Considering the fact that CANDU (Canada Deuterium Uranium) utilizes on-power refueling to compensate for the reduction of reactivity due to fuel burnup, in the CANDU fuel management analysis, snapshots of power and burnup distributions can be obtained by simulating and tracking the reactor operation over an extended period using various tools such as the $^*SIMULATE$ module of the Reactor Fueling Simulation Program (RFSP) code. However, for some studies, such as an evaluation of a conceptual design of a next-generation CANDU reactor, the preferred approach to obtain a snapshot of the power distribution in the core is based on the patterned-channel-age model implemented in the $^*INSTANTAN$ module of the RFSP code. The objective of this approach is to obtain a representative snapshot of core conditions quickly. At present, such patterns could be generated by using a program called RANDIS, which is implemented within the $^*INSTANTAN$ module. In this work, we present an alternative approach to derive the patterned-channel-age model where a simulated-annealing-based algorithm is used to find such patterns, which produce reasonable power distributions.
