This sudy aimed to evaluate the effect of Punsimgieum-gamibang(分心氣飮加味方) on emotionality and sleep disorder. Punsimgieum(分心氣飮) has been used for insomnia, trembling, emotionality caused by strong mental stimulation and continuous stress in Oriental Medicine. And it was reported that Punsimgieum had anti-stress and anti-depression effect. Animals were devided into two groups : control group and Punsimgieum-gamibang group.Emotionality was tested in open-field with five indexes : walking, rearing, grooming, excretion and start latency. For the study of sleep disorder, after two groups had been given caffeine into abdomen, activity amount in animals was assessed for daytime and then the average percentage of sleep in two groups was calculated.The following results were observed.1. In peripheral and central partition, meditaion group walked more than control group. The difference between two groups was statistically significant.2. In rearing and grooming frequency, there was difference between two groups, but it was not statistically significant. 3. In grooming. excretion and start latency. there was no difference between two groups.4. There was no difference in the average percentage of sleep between two groups.

The purpose of this study is to analyze the characteristics of older women's torso shapes. The data was collected from the 7th Size Korea, which featured 453 women between the ages of 70-85. A factor analysis was performed of 31 indices, including seventeen based on height and length measurements, eight based on circumference measurements, and six based on torso flattening. The torso shape was determined from seven factors: torso flatness ratio, shape of the side upper torso, vertical size of upper torso, silhouette of the torso, silhouette of the bust and abdomen, shape of the hip, and the vertical size of the back of upper torso. The torso shapes of older women were classified into three types based on the results of the factor analysis. Type 1 is called the large rectangle type. They have the lowest degree of forward bend in the torso, the largest vertical and horizontal size, a round body shape, and the upper torso is gently curved. Type 2 is called the inverted triangle type. They also have a round body shape, but the abdominal size is relatively small compared to the size of the bust, and also have an open and drooping bust, and the biggest degree of forward bend in the torso. Type 3 is called the square type. They are characterized by drooping hips, the smallest vertical and horizontal sizes, and the gentlest curve of the torso.

Purpose: Intracorporeal esophagojejunostomy during reduced-port gastrectomy for proximal gastric cancer is a technically challenging technique. No study has yet reported a robotic technique for anastomosis. Therefore, to address this gap, we describe our reduced-port technique and the short-term outcomes of intracorporeal esophagojejunostomy. Materials and Methods: We conducted a retrospective review of patients who underwent a totally robotic reduced-port total or proximal gastrectomy between August 2016 and March 2020. We used an infra-umbilical Single-Site^® port with two additional ports on both sides of the abdomen. To transect the esophagus, a 45-mm endolinear stapler was inserted via the right abdominal port. The common channel of the esophagojejunostomy was created between the apertures in the esophagus and proximal jejunum using a 45-mm linear stapler. The entry hole was closed with a 45-mm linear stapler or robot-sewn continuous suture. All anastomoses were performed without the aid of an assistant or placement of stay sutures. Results: Among the 40 patients, there were no conversions to open, laparoscopic, or conventional 5-port robotic surgery. The median operation time and blood loss were 254 min and 50 mL, respectively. The median number of retrieved lymph nodes was 40.5. The median time to first flatus, soft diet intake, and length of hospital stay were 3, 5, and 7 days, respectively. Three (7.5%) major complications, including two anastomosis-related complications and a case of small bowel obstruction, were treated with an endoscopic procedure and re-operation, respectively. No mortality occurred during the study period. Conclusions: Intracorporeal esophagojejunostomy during reduced-port gastrectomy can be safely performed and is feasible with acceptable surgical outcomes.

Background Groin wounds occurring after vascular surgical site infection, oncologic resection, or occasionally orthopedic surgery and trauma may represent a surgical challenge. Reconstruction of these defects by the usual workhorse flaps may be contraindicated following previous surgery and in patients with lower limb lymphedema or extreme morbidity. Methods This study included 15 consecutive patients presenting with inguinal wounds after vascular or general surgery that required debridement and soft tissue coverage. All cases had absolute or relative contraindications to conventional reconstructive techniques, including a compromised deep femoral artery network, limb lymphedema, scarring of potential flap harvesting sites, or poor overall condition. Abdominal adipocutaneous excess enabled the performance of adipocutaneous advancement flaps in an abdominoplasty-like fashion. Immediate and long-term outcomes were analyzed. Results Soft tissue coverage was effective in all cases. Two patients required re-intervention due to flap-related complications (venous congestion and partial flap necrosis). All patients fully recovered over a mean±standard deviation follow-up of 2.4±1.5 years. Conclusions Abdominal flaps can be an effective and simple alternative technique for inguinal coverage with reproducible outcomes. In our experience, the main indications are a compromised deep femoral artery network and poor thigh tissue quality. Relative contraindications, such as previous open abdominal surgery, should be considered.

Artificial fertilization of ice fish, Mypomesus transpaciticus nipponensis caught at Milyang-river and Osib-chun brook was performed in March 24, 1990, and the hatched larvae were reared for 25 days to describe the development of eggs and larvae. Fertilized eggs were spherical in shape, measuring $0.85\~1.05\;mm$ in diameter (mean: 0.97 mm) and translucent adhesive with many small-sized oil globules on the surface. Hatching in the indoor tank started from the 170 hours after fertilization under $16.5^{\circ}C$ water temperature. Newly-hatched larvae were measured $3.85\~4.25\;mm$ in total length (mean: 4.05 mm), and mouth and anus were not yet open. They had one yolk sac on the anterior part of abdomen, straight-type's notochord, and $52\~54$ myotomes. The larva of 5 days old transformed to postlarval stage and measured $5.20\~5.65\;mm$ (mean: 5.37 mm) in total length. As the yolk sac was completely absorbed, mouth and anus were open, and they fed rotifers vigorously. In 20 days after hatching, the larvae grew to 8.38 mm in TL, and the caudal notochord flex at $45^{\circ}$. In 25 days after hatching, total length reached 9.63 mm. The pan of the fin-fold of the future dorsal and anal fins became high.

The difference of radiation dose of MDCT due to different protocols between hospitals was analyzed by CTDI, DLP, the number of Slice and the number of DLP/Slice in 30 cases of the head, the abdomen and the chest that have 10 cases each from MDCT examination of the department of diagnostic imaging of three general hospitals in Gyeongsangbuk-do. The difference of image quality, CTDI, DLP, radiation dose in the eye and radiation dose in thyroid was analyzed after both helical scan and normal scan for head CT were performed because a protocol of head CT is relatively simple and head CT is the most frequent case. Head CT was significantly higher in two-thirds of hospitals compared to A hospital that does not exceed a CTDI diagnostic reference level (IAEA 50mGy, Korea 60mGy) (p<0.001). DLP was higher in one-third of hospitals than a diagnostic reference level of IAEA 1,050mGy.cm and Korea 1,000mGy.cm and two-thirds exceeded the recommendation of Korea and those were significantly higher than A hospital that does not exceed a diagnostic reference level (p<0.001). Abdomen CT showed 119mGy that was higher than a diagnostic reference level of IAEA 25mGy and Korea 20mGy in one-third. DLP in all hospitals was higher that Korea recommendation of 700mGy.cm. Among target hospitals, C hospital showed high radiation dose in all tests because MPR and 3D were of great importance due to low pitch and high Tube Curren. To analyze the difference of radiation dose by scan methods, normal scan and helical scan for head CT of the same patient were performed. In the result, CTDI and DLP of helical CT were higher 63.4% and 93.7% than normal scan (p<0.05, p<0.01). However, normal scan of radiation dose in thyroid was higher 87.26% (p<0.01). Beam of helical CT looked like a bell in the deep part and the marginal part so thyroid was exposed with low radiation dose deviated from central beam. In addition, helical scan used Gantry angle perpendicularly and normal scan used it parallel to the orbitomeatal line. Therefore, radiation dose in thyroid decreased in helical scan. However, a protocol in this study showed higher radiation dose than diagnostic reference level of KFDA. To obey the recommendation of KFDA, low Tube Curren and high pitch were demanded. In this study, the difference of image quality between normal scan and helical scan was not significant. Therefore, a standardized protocol of normal scan was generally used and protective gear for thyroid was needed except a special case. We studied a part of CT cases in the local area. Therefore, the result could not represent the entire cases. However, we confirmed that patient's radiation dose in some cases exceeded the recommendation and the deviation between hospitals was observed. To improve this issue, doctors of diagnostic imaging or technologists of radiology should perform CT by the optimized protocol to decrease a level of CT radiation and also reveal radiation dose for the right to know of patients. However, they had little understanding of the situation. Therefore, the effort of relevant agencies with education program for CT radiation dose, release of radiation dose from CT examination and addition of radiation dose control and open CT contents into evaluation for hospital services and certification, and also the effort of health professionals with the best protocol to realize optimized CT examination.

Two major sex pheromone components (Z-8-dodecenyl acetate and E-8-dodecenyl acetate) are known in the peach fruit moth, Grapholita molesta. From a putative biosynthetic pathway of these sex pheromone components, delta 10 desaturase ($10{\Delta}$ DES) has been proposed to play a crucial role in synthesizing a species-specific stereoisomer of the double bond. However, its molecular identity was not known. This study determined a putative desaturase (Gm-comp1575) as a $10{\Delta}$ DES candidate from G. molesta transcriptome constructed from the sex pheromone gland. Its open reading frame encodes 370 amino acid sequence with a predicted molecular weight at 43.2 kDa and isoelectric point at 8.77. It was predicted to have four transmembrane domains and six glycosylation sites at N-terminal or cytosolic domains. A phylogenetic analysis with its predicted amino acid sequence indicated that Gm-comp1575 is closely related with known $10{\Delta}$ DES genes of other insects. Gm-comp1575 transcript was detected in female adults at sex pheromone gland and other abdominal tissues. RNA interference of Gm-comp1575 significantly reduced attractiveness of virgin females in apple orchard compared to control females. These results suggest that Gm-comp1575 is associated with sex pheromone biosynthesis of G. molesta.

Fumigation using chlorine dioxide ($ClO_2$) has been regarded as a potential control technique against stored grain insect pests. The control efficacy can be enhanced with increase of opening rates of spiracles by facilitating the toxic gas delivery to internal body. To test this hypothesis, this study used the Indianmeal moth, Plodia interpunctella, which was known to be susceptible to $ClO_2$, and analyzed the opening rate of spiracles. A total of 9 pairs of spiracles were observed in P. interpunctella larvae, in which one pair was located on the prothorax and eight pairs were on the abdomen. Within the body, the spiracles were connected to longitudinal and transverse tracheal trunks. The open spiracles were determined by the dye-infiltration method. Based on this method, the opening rate of spiracles increased up to about 60% with increase of ambient temperatures. Furthermore, exposure to carbon dioxide stimulated the opening rate of spiracles up to about 95%. In contrast, exposure to $ClO_2$ prevented the spiracle opening and resulted in only 25% of spiracles in an opening state. The addition of carbon dioxide to $ClO_2$ treatment rescued the opening rate of spiracles as much as the carbon dioxide single treatment. Based on this modulatory activity of carbon dioxide against spiracles, the combined treatment of $ClO_2$ with carbon dioxide resulted in significant increase of its toxicity against P. interpunctella compared to a single $ClO_2$ treatment.

Objectives : The purpose of this study is to evaluate the feasibility of further acupuncture research as an effective alternative and safe treatment for abdominal pain control in patients with pancreatitis. Methods and Results : This study is an open-label, assessment-blind, parallel designed pilot clinical trial. Thirty participants will be assigned to the acupuncture group(n=15) and usual care group(n=15). All patients will receive the conventional standard-of-care(SOC) therapy, but only the experimental group will receive acupuncture therapy six times a week, and the duration of acupuncture therapy will be held up to 12 weeks or until the pains are to be resolved. For the conventional SOC therapy, painkiller will be given. In treatment group, the subjects will receive the identical SOC therapy in combination with electroacupuncture therapy on twelve acupuncture points(LI4, PC6, SP6, GB39, ST36, ST37), and auricular acupuncture therapy on five auricular acupuncture points(Sympathetic, Shen Men, Abdomen, Pancreas gall, and Spleen). The primary outcome will be measured using the visual analogue scale(VAS), and the secondary outcome will be measured using the painkiller demand, quality of life index and severity of pancreatitis by abdominal computed tomography(CT). Assessments will be made at baseline and at week 1, 4, 8 and 12. Results of abdominal CT will be evaluated at baseline and at week 12. Conclusions : The result of this trial will provide a basis for the effectiveness and safety of acupuncture treatment for abdominal pain in patients with pancreatitis.

Objectives: An outbreak of dermatosis occurred at a city gas manufacturing factory in Pohang in Aug, 1998. The authors conducted a study to find the cause and prevent the dermatosis, Methods: We conducted a questionnaire survey of 73 workers in the factory twice, once or Aug. 14th and then Sept. 11th, 1998. Also, a dermatologist examined their skin lesions. We suspected ants as the cause, so we collected them for identification. Results: Twelve cases of dermatosis were identified with an attack rate of 16.4%. The attack rates were not different by age, educational level or tenures. The attack rates were 66.6% among production workers, 2.0% among clerical workers, 16.7% among tank trailer drivers and 0% among guards. The attack rate among production workers was significantly higher than that of the others (<0.01). There were no histories of the same dermatosis for the past one year. Histories of other skin diseases and allergies were very rare in both cases with skin diseases and control. Multiple, pruritic, rice-grained to bean sized erythemafous macules or papules with a central biting point could be found after initial severe itching occurred, Three cases showed signs of dermatosis with an allergic nature. The onset of dermatosis was between July 30 and Aug 12 and the durations varied from 5 days to over a month. The most frequent sites of stir lesions were the chest and abdomen (60.6%), and they were also observed on the neck (33.3%), arms (33.3%), shoulders (16.7%) and back (16.7%). Over 10 ants with their wings were collected in the work place and identified as Pachycondyla chinensis, subfamily Ponerinae. Conclusions : We thought that the outbreak of dermatosis was brought about by the ants flying into the work place through the open windows. Further studies on the factors contributing to the prosperity of the ants in this area are needed.
