Today's world is experiencing rapid technological advancement like never before. The ever-changing technology space has overwhelmed citizens with a substantial load of information, which has made it difficult for them to keep up with the technology awareness. This review paper is written to provide information about the Internet of Things in a way that technical along with nontechnical individuals can understand the definition, historical evolution, components, and scope of IoT technology. Relevant literature published between January 2009 and February 2023 was included in this paper. The applications of the Internet of Things in healthcare have been a special focus of this paper as IoT has massive potential in this field and healthcare professionals often face significant issues in keeping their technology knowledge up to date. Moreover, some of the most common issues associated with IoT introduction in healthcare are also discussed in the paper along with some suitable recommendations. Although, IoT can significantly transform our lives and can introduce convenience and efficiency, particularly in the healthcare sector. However, its adoption in healthcare is still a major task due to various challenges presented by the health workforce. Thus, in-depth empirical research is suggested to assist the IoT technology transition.

Most special health care needs (SHCN) people suffer from oral health problems due to high incidence and severity of oral disease. The aim of the present study was to investigate the characteristics of dental treatment provided in this patient population. The study population comprised 485 SHCN patients who visited Kyung Hee University Dental Hospital from 2006 to 2014. Based on the medical record, the date were evaluated according to age, gender, type of disorder, reason for visit, type of behavior management, and type of dental treatment. The most common age group was 7-12 year olds (26%). The chief compliant was dental caries (39%), as followed by oral exam (12%) and trauma (12%). Approximately half of SHCN patients (45.9%) was treated under behavior management. Restorative treatment was the most common procedure with the average of 2.9 teeth treated per patient. The results of the present study may be valuable for establishing the data of SHCN patients for primary dental care.

Pancreatic cancer is the eighth most common cancer and the fifth most common cause of cancer-related deaths in Korea. Despite the increasing incidence and high mortality rate of pancreatic cancer, there are no appropriate surgical practice guidelines for the current domestic medical situation. To enable standardization of management and facilitate improvements in surgical outcome, a total of 10 pancreatic surgical experts who are members of Korean Association of Hepato-Biliary-Pancreatic Surgery have developed new recommendations that integrate the most up-to-date, evidence-based research findings and expert opinions. This is an English version of the Korean Surgical Practice Guideline for Pancreatic Cancer 2022. This guideline includes 13 surgical questions and 15 statements. Due to the lack of high-level evidence, strong recommendation is almost impossible. However, we believe that this guideline will help surgeons understand the current status of evidence and suggest what to investigate further to establish more solid recommendations in the future.

As homework, a total of 32 seventh grade science-gifted students were asked to observe the moon at daily intervals for one month duration. They were also asked to take the photos and to record relevant variables in a given format. The purpose of the task was to investigate what students thought, as they observed the moon. The results show that students paid attention mainly to the position of the moon relative to other variables such as the date in the lunar calendar, the observer's position on the earth, and the position of the sun. Overall students' response implied that students did not observe the lunar phase in relation with relevant variables. Some reponses from students show common misconceptions such as the cause of the lunar phase to reflect the shadow of the earth. However, some responses reveal students' idea that has been rarely reported in the previous researches. For example, some students drew the moon to revolve in the opposite direction. Significant number of students drew the sun's position to be due west before the full moon and due east after the full moon. Few students recognized the relation between the time of observation and observer's position on the earth. The results of current research suggest that not only the education but also the research needs to be expanded to consider informal environment such as the actual field conditions.

Scoliosis describes a lateral curvature of the spine and is often associated with cosmetic and functional impairments due to severe deformity of the spine. The incidence of adolescent scoliosis is 2-4% of children between 10 and 16 years of age. Eighty five percent of them are idiopathic, in which the most common type of scoliosis is right side-bending. In addition, it is classified into congenital, and secondary scoliosis such as neuromuscular disease and neurofibromatosis. Congenital scoliosis is associated with abnormalities of urinary system(20%), congenital heart diseases(15%), and other abnormalities(10%) such as syringomyelia. We experienced a case of scoliosis by a foreign body(a pencil) in the colon which has never been reported up to date. A brief review of the literature was made.

Soybean (Glycine max L. (Merr) is commonly consumed and found in major foods including soymilk, soy sauce, tofu, and soy sprout in Korea and east Asia. In addition, it is common to cook the whole seeds with rice. Soybean is known to have ranges of health benefits including antiaging, anticancer, neuroprotective and antidiabetic taken either as supplement or dietary food. Anthocyanins and flavonoids in G. max are found to be the main contributors to such wide arrays of health benefits. Due to increasing economic values of soybean, development of specialty soybean cultivars is becoming an area of interest worldwide. In this study, 746 black soybean accessions from National Agrobiodiversity Center were characterized as part of an attempt to identify important germplasms of G. max. Seed coats of each accession were analyzed for their total anthocyanin, cyanidin 3-O-Glucoside (C-3-O-G), delphinidin 3-O-glucoside (D-3-O-G), petunidin-3-O-glucoside (Pt-3-O-G), and their whole seeds for crude protein contents. HPLC was used to determine and quantify the anthocyanin compositions while crude protein was determined using Kjeldahl method by Kjeltec auto-analyzer (Kjeltec 8400, Foss, Sweden). Accessions were grouped according to their anthocyanins and protein contents; the mean content of which were correlated to agronomic traits including maturity date, one hundred seed weight, cotyledon color and seed lust color. The results indicated that the total anthocyanin content (TAC) ranged from 273.77 to 6250.52 mg/100 g, with mean value of 1853.03 mg/100 g while the crude protein content (CPC) being between 33.43 and 47.51%, with mean value of 40.81%. The highest number of accessions (45.97%) showed TAC between 1000~1900 mg/100 g while 30.96% of accessions showed CPC between 41~43%. Among the 746 accessions considered, 11 (IT142935, 175818, 175855, 177191, 177209, 177211, 177214, 177216, 177218, 177220, 177274) of them showed TAC above 4000 mg/100 g. C-3-O-G was found to be the major contributor to TAC showing strong correlation. Accessions with green cotyledon color showed high mean TAC compared to those having yellow cotyledon color, and accessions with dull seed lust color showed high mean TAC than those having shiny seed lust color. One hundred seeds weight and maturity date showed positive correlation with all anthocyanin contents, except for Pt-3-O-G in the latter case. The overall result of the present study could be used as background for developing new black soybean cultivars and breeds with high anthocyanin and protein contents. The result depicted that many of the accessions could be used as potential parental lines.

Objectives : The purpose of this study is to provide data to guide dementia health-care policy in Korea and to establish the position of Korean medical specialists in long-term care hospitals by analyzing the data of dementia inpatients. We analyzed the actual condition of dementia patients in care hospital and the effect of Western-Korean cooperative medicine on the progress of dementia. Methods : From January 1, 2016 to December 31, 2016, inpatients who were diagnosed with dementia at Mungyeong municipal long-term care hospital and admitted for more than 3 months were enrolled. Their medical records and simple tests were analyzed retrospectively. Results : We examined the detailed diagnosis, including both main and sub diagnosis, and Alzheimer disease dementia, at 97%, was the most common. At the time of admission, Korean Version of the Mini-Mental State Exam (K-MMSE) analysis showed that severe dementia affected 52%, and most were rated as Geriatric Depression Scale (GDS) 6. Based on the admission date, the results of a simplified test applied to the dementia patients every 6 months showed an maintain in the K-MMSE and GDS scores in 83%. Conclusion : The results of this study show that the rate of progression of dementia is somewhat lower in inpatients with moderate to severe Alzheimer's who have received Western-Korean cooperative treatment. However, due to institutional limitations, long-term inpatients such as those with dementia do not receive active traditional Korean medical treatment; hence, it is necessary to improve the national institution of traditional Korean medicine in long-term care hospitals.

1. Objectives Due to a lack of detail guidelines for prescriptions to ordinary and pathological symptoms in ${\ulcorner}$DongyiSuseBowon${\lrcorner}$, doctors depend on their own decision when give a prescription. This study aimed to compare ordinary symptoms and pathological symptoms in regards to six prescriptions being applied to Soyangin to utilize them as guidelines in practices. 2. Methods Date were collected from September, 2003 to August, 2004 at the Sasang Constitutional clinic of Pohang Oriental Medicine Hospital. Patients were first asked to fill Out a questionnaire of symptoms that they had at the time of visiting. Data from 273 Soyangin patients whose chief complains got alleviated after taking the prescribed drug were analyzed to examine if there were differences in prescriptions according to ordinary or pathological symptoms complained. 3. Results and Conclusions 1. Hyungbangpaedog-san(Paedog) was given more to the patients having good digestive function than Hyungbangjihwang-tang(Hyungji) and Hyungbangdojeok-san (Dojeok) ; Dojeok was given for bloating symptom compared to Hyungbangsabaek-san(Sabaek). Yangkyuksanhwa-tang(Yangkyuk) and Dojeok were more like for patients with stomachache compared to Paedog. Doghwaljihwang-tang(Dogji) was prescribed to patients complaining frequent voiding compared to Sabaek while Sabaek was given for patients who prefer cold water and feel their body warm compared to other prescriptions. Yangkyuk and Dojeok were prescribed more likely to patients with feeling of suffocation than Sabaek. 2. In symptom comparisons between one prescription and the group of the rest of 5 prescriptions, Paedog was found to be prescribed when patients had good digestive function while Dojeok was given in symptoms cases of indigestion, bloating, constipation and dizziness. Sabaek was applied more for patients having tendency of preferring cold water and feeling of heat body as well as good digestive function. Hyungji was used for patients complaining a symptom of fatigue, in addition Yangkyuk was given to patients who were nervous, sensitive, or impatient when compared to Other prescriptions. Dogji was applied to frequent voiding, insomnia, tingling of extremities, backache or leg pain, or in case of tendency of catching a common cold.

We develop a dispatching policy for stochastic scheduling simulation especially for a continuous manufacturing system with machine breakdowns. The proposed dispatching policy computes an urgency index with the consideration of re-heating, setup cost and remaining due date. Prioritized by the index, we execute swapping or reassigning material sequences so as to minimize the total penalty cost. To evaluate the performance of the proposed policy, a discrete event simulation is developed. With 200 data sets and 20 iterations, we compare the performance of the urgency policy with those of SPT (Shortest Processing Time) and FCFS (First Come First Serve) which are the most common policies. The result shows that the proposed policy consistently gives the lowest total costs by reducing the penalty costs for lateness.

Kwashiorkor is a syndrome of severe protein malnutrition, which manifests itself in hypoalbuminemia, diarrhea, dermatitis, and edema. It can be life-threatening due to associated immune deficiency and an increased susceptibility to infections. Kwashiorkor should be treated early with nutritional support and the control of infection. Dilated cardiomyopathy may develop during the treatment and in such cases a poor prognosis is expected. Kwashiorkor has been known as a common disease of poor countries. To date, in fact, there has been no report of kwashiorkor leading to death in technically advanced countries. We here report a fatal case of a baby girl admitted with kwashiorkor. She had been fed only with cereal grain mixed with juice, without any protein supplement, for 2 months. This diet was deficient not because of poverty, but due to the illiteracy of her parents. The patient suffered from diarrhea, whole body edema, hypothermia, and dermatitis. Laboratory findings revealed an immune-deficient state featuring leukopenia and decreased immunoglobulin. Blood and urine cultures revealed Alcaligenes Xylosoxidans growth. The patient was fed frequent small amounts of protein-containing formula and intravenous albumin and micronutrients were administered for nutritional support. She was also treated with intravenous immunoglobulin and antibiotics in order to control infection. Nevertheless, she developed dilated cardiomyopathy and multi-organ failure and died. We review this case in light of the literature.
