Cascade Stomach is commonly found in obese patients. This study examined the physical factors, such as gender, age, height, weight and level of obesity, associated with a cascade stomach. Over a 12 month period between 2007 a series upper gastrointestinal examinations were carried out on 3,320 people, which included 564 patients with a Cascade Stomach. The results are as follows : 1. A cascade stomach was observed in 564(16.9%) out of 3,320 subjects. 2. A body mass index(BMI) > 120% was observed in 226 of the 564 cascade stomach patients. 3. Among those with a BMI > 120, 63.7% were female, 45.6% were aged between 50-59 years, 49.1% were between 151-160 cm in height and 31.0% were above 76 kg in weight. 4. The symptoms observed in the cascade stomach and obesity groups were subclinical(62.6% and 57.5%, respectively), dyspepsia(16.8% and 17.3%, respectively) and gastric soreness(10.8% and 15.0%, respectively). The incidence of a cascade stomach is higher in those with obesity. In addition, there is a higher incidence in females, those aged between 50 and 59, those between 151 and 160 cm in height and those weighing more than 76 kg. The main symptoms observed were subclinical, followed in order by dyspepsia and gastric soreness. This study showed a strong association between a cascade stomach and obesity. However, more studies will be needed to confirm this.

It is well known that the exercising and stimulating of fingers have an important bearing on the brain. We take note of the fact and develope a game device for improving one's health and brain ability in respect of the education and training. Especially, we develope the device focused on the balanced exercising of five finger for improving brain function. The game device is possible to used in two-ways, namely online and off-line mode. In online mode, the device is connected with other visual devices such as smart phone and smart TV and communicated with Bluetooth and it is used as a MMI(multi-modal interface) device. Whereas, in off-line mode the game device works independently and it makes possible to enjoy auditorial and tactual games without video images for promotion of brain activity and emotional cultivation. For certification of the device, we implement two games(a fishing game for off-line mode and a shooting game for online mode) for people of all age, especially good for the elderly. It is usable as a game device to offering the elderly a great help for preventing impairment of the cognitive functions.

The purpose of this study was to compare the compression force and thickness of the compressed breast between mediolateral oblique and craniocaudal mammography. This population consisted of 204 paired mediolateral oblique and craniocaudal mammography obtained on one mammographic unit by certified mammography technologists during 2 month period. The women examined were $30{\sim}59$ years old with breast implants, the patients were classified into 3 groups according to age, $30{\sim}39$, $40{\sim}49$, and $50{\sim}59$, prior breast cancer, mastectomy or breast deformity were excluded. The digital readout of compressed breast compression force and thickness was recorded. Mammographic positioning was assessed using standard criteria. The mean compression force of the compressed breast on the craniocaudal projection was less than the mean compression force on the mediolateral projection(14 versus 13.88 daN, p<0.05). The mean thickness of the compressed breast for mediolateral projection was 41.46 mm and that for the craniocaudal projection was 39.50 mm(p<0.05). The compressed breast is higher or thicker on mediolateral oblique than on craniocaudal mammography.

The study conducted a survey on the perception level for radiological technologists with 321 nurses and auxiliary nurses working at university hospitals in Busan in order to supply preliminary data to enhance the status as well as professional images of radiological technologists. The result shows the perception level of $3.02{\pm}0.42$ with the highest score for the professional image and the lowest score for the business image. By question, 'they are professional' gets the highest score while 'they understand problems of patients well' gets the lowest. Among respondents, those who are well aware of education courses as well as leading organization of examination and who answer as a health care provider or a medical technician under the medical law show a high level of perception while those who answer as technician show a low perception level. Those who agree with radiologists as a career and consider their status as high in medical institutions have a high level of perception. In order to improve the perception level, individuals as well as associations' promotion and strategies are required to fix the title and enhance the negative images through active interests and kind attitudes toward patients. Also, efforts to escape from previous images limited to technical colleges, to vitalize academic conference and remedial education, and to frame the law of professional radiological technologists system are asked to heighten the qualification and status of radiological technologists. More than that, advertising and monitoring via mass media are needed to develop the image as professional career men as well.

This study tried to investigate the effects of the adaptation of middle-aged and elderly adult learners to college life on happiness. For this purpose, a questionnaire survey and analysis were conducted on 321 middle-aged and older adults studying at two-year and four-year colleges in Daegu and Gyeongbuk Province, and the results are as follows. First, college life adaptation according to the general characteristics of middle-aged and elderly learners are higher for those in their 50s and 2nd grade in good health condition. Happiness was the highest women, 60s and those in the form of households where only couples live. Second, there is a static correlation between the adaptation of middle-aged and elderly adult learners to college life and happiness, and the correlation between satisfaction with internal growth and satisfaction with meaning was the highest. Third, it was found that middle-aged and elderly adults' adaptation to college life influenced happiness, and the adaptation to adult student relationships, which is the lower part of the adaptation to college life, had the greatest impact on happiness. The above research results suggest that the various positive experiences experienced in university life can affect happiness by easing student relationships, psychological stability, and physical tension, and improving one's own satisfaction with internal growth.

In this paper, the remote care of medical beds with multiple body pressure sensors is described. Falling is one of the factors that seriously threaten the safety of patients and harm their health. In this study, a new bed was developed to overcome this. The bed system consists of a keyboard that can operate, a keyboard controller that manages the movement of the keyboard, a sensor that measures body pressure, a sensor controller that transmits and receives sensor values, a main controller that checks it and operates automatically or manually according to the algorithm, and a server that oversees all these information. The bed system checks the patient's location through a sensor and wirelessly alerts the server through the main controller when the patient determines that there is a risk of falling, so that the nurse or nurse can recognize the patient's dangerous condition. The server may receive state data transmitted from the wired/wireless terminal to monitor whether the bed system is operating normally. The controller of the keyboard operates a keyboard-type mechanism and automatically controls the prevention of bedsores connected by body pressure sensors to physically separate the area to which the patient's pressure is applied to prevent bedsores. The main controller checks the presence of the patient's bed and transmits it to the server. In conclusion, the proposed system can smart monitor the user's state and perform remote care.

This study attempted to examine the relationship between college students' participation in the learning community according to the characteristics of learners. To this end, the learning community divided the subject-linked learning community into a foundation learning community and an advanced learning community. Learner characteristics were classified by gender, grade, and major. A cross-analysis was conducted to examine the difference between participation in the foundation learning community and the advanced learning community according to the learner characteristics. The results are as follows. First, the participation of female students in the foundation learning community and the advanced learning community was higher than that of male students, but it was not statistically significant. Second, it was found that there was a significant difference in participation in the learning community according to the grade. In the case of the foundation learning community, the participation rate of the first and second year students was relatively high, and in the case of the advanced learning community, the ratio of the third and fourth year students was relatively high. Third, as a result of examining the differences by major, it was found that the participation rate of health and welfare universities was high in both the foundation learning community and the advanced learning community. Based on these results, discussions and suggestions are presented.

The government's strengthening of the standards for mentally ill patients and expanding the scope of examinations to the entire nation reflects the changing times. According to the OECD's announcement (2021), the incidence of depression and anxiety has more than doubled since the prolonged COVID-19 pandemic in countries around the world, with Korea's prevalence ranking first. However, only 12.1% of those who have been diagnosed with mental disorders received counseling and treatment from experts. The difference between depression and simple depression is significant depending on whether it is medically treated or temporary, but it can be seen that the continuation of depression is depression. In order to reduce this depression, Kandinsky's work was visualized and created. In a study conducted by changing the playback speed of the produced Kandinsky image, beta and gamma values, which showed the largest deviation when compared to depressive patients and normal people, increased significantly when viewed at 90fps, which was most effective in relieving depression. Artistic creations are bound to be accepted differently depending on the individual's perspective, but it is hoped that research that can improve the phenomenon of individuals suffering from depression by integrating artificial intelligence and traditional mental health approaches will be further developed and widely used for treatment.
