  • Background: The purpose of this study was to compare the clinical safety and effect with and without additional submucosal midazolam to oral chloral hydrate and hydroxyzine when used for pediatric conscious sedation in a clinical dental environment. Methods: Thirty one cases of pediatric conscious sedations were performed in this study. Selection criteria included good health (ASA I), under 6 years old, 20 kg of body weight, uncooperative behavior and the need for sedation to receive dental treatment including anesthesia and restorative or surgical procedure for at least two teeth. In each visit, patients were randomly assigned into one of two groups; CH group: chloral hydrate (60 mg/kg), hydroxyzine (1 mg/kg), CH-M group: chloral hydrate (60 mg/kg). hydroxyzine (1 mg/kg) and submucoal midazolam (0.1 mg/kg). 50% nitrous oxide-oxygen was maintained during the sedation period Sedations were monitored using a pulse oximeter for estimating pulse rate (PR) and percutaneous oxygen saturation ($SpO_2$). Behavior response rated using Houpt's scale and need of restraint was assessed every 2 minutes through 30 minutes of operative procedure reviewing the videotape recording. Evaluation of overall behavior success was performed using modified overall behavior rate of Houpt's scale. Data was analyzed using t-test. Results: PR and $SpO_2$ for both groups remained within the normal values. The mean scores for sleep and movement of CH-M group were higher than those of CH group (P < 0.05). There were no significant difference in mean score for crying between two groups. The mean scores of overall behavior of CH-M group was higher than those of CH group (P < 0.01). Reinstraint of CH-M group was less required than that of CH group (P < 0.05). Conclusions: Oral chloral hydrate (60 mg/kg) and hydroxyzine (1 mg/kg) combined with submucosal injection of midazolam was safer and showed more improved sedation effect than oral chloral hydrate (60 mg/kg) and hydroxyzine (1 mg/kg) without midazolam for sedation of pediatric dental patients.

  • Rendering the brain ischemic would evoke the cerebral ischemic reflex which is characterized by an arterial pressor response, apnea and bradycardia. Since the rostral ventrolateral medulla (RVLM) is known to play a key role in the maintenance of normal cardiopulmonary activity, during the cerebral ischemic reflex some cardiac related cells should be excited and respiration related cells inhibited. In this context, the responses of RVLM neurons to systemie and focal hypoxia were analyzed in the present study. Twenty-five adult cats of either sex were anesthetized with ${\alpha}-chloralose$ and the single neuronal activities were identified from RVLM area. For the induction of focal hypoxia in the recording site, sodium cyanide was applied iontophoretically and for systemic hypoxia the animal was ventilated with nitrogen gas for a twenty-second period. Cellular activities were analyzed in terms of their discharge pattern and responses to the hypoxia by using post-stimulus time and single-pass time histograms. Of eighteen cardiac related cells recorded from the RVLM area, twelve cells were excited by iontophoresed sodium cyanide and of twenty-five respiration related cells, fourteen cells were excited by iontophoresed sodium cyanide. Remaining cells were either inhibited or unaffected. Eight of fifteen cells tested with iontophoresed sodium lactate were excited and remaining seven cells were inhibited. Systemic hypoxia induced by nitrogen gas inhalation elevated the arterial blood pressure, but excited, inhibited or unaffected the single neuronal activities. Some cells showed initial excitation followed by inhibition during the systemic hypoxia. Bilateral vagotomy resulted in a decrease of arterial pressor response to the systemic hypoxia, and a slight decrease in the rhythmicity related to cardiac and/or respiratory rhythms. The single neuronal responses to either systemic or focal hypoxia were not affected qualitatively by vagotomy. From the above results, it was concluded that the majority of the cardiac- and respiration- related neurons in the rostral ventrolateral medulla be excited by hypoxia, not through the mediation of peripheral chemoreceptors, and along with the remaining inhibited cells, all these cells be involved in the mediation of cerebral ischemic reflex.

  • This case report suggests the potential effects of Korean medicine for the gait disturbance and posture instability of Multiple System Atrophy-Parkinsonism (MSA-P). A patient with MSA-P who had gait disturbance and posture instability was given a series of Korean medicine, including acupuncture, pharmacopuncture, electro-acupuncture, moxibustion, and herbal medicine, for 15 days of hospitalization. During the hospitalization period, the severity and progression of the disease was measured with the Unified Multiple System Atrophy Rating Scale (UMSARS) and a video recording of a 20-meter round timed walking test. The UMSARS Part I and II scores decreased from 14 to 5 and 9 to 5, respectively. An improvement was also noted in standing and walking posture, and the walking time was shortened from 30 to 25 seconds in the 20-meter round-trip walking test. Dysarthria, dysphagia, and non-motoring symptoms like sleep behavioral disorders and constipation were also improved. The findings of this case study suggest that this series of Korean medicine has potential therapeutic effects for patients with MSA-P with motor and non-motor symptoms.

  • 본 연구는 성페로몬에 대한 열대거세미나방 수컷 성충의 촉각 반응 및 중복 교미 여부를 확인하기 위해 수행하였다. 성페로몬 성분인 Z9-14:Ac에 대한 열대거세미나방 수컷 성충의 촉각 반응은 농도 의존적으로 농도가 증가할수록 크게 나타났다. 조사한 7성분 중 Z9-14:Ac 성분에 대한 촉각 반응이 가장 컸다. 성페로몬의 혼합 성분에 대한 촉각 반응이 단일 성분에 비해 컸다. 열대거세미나방 수컷 성충은 실험실 조건에서 중복교미가 가능하고, 첫 교미율이 58.3%인데 비해서 두 번째 교미율이 72.2%로 증가하였다. 교미한 수컷 성충의 촉각 반응과 교미하지 않은 수컷 성충의 촉각 반응의 차이가 없었다. 성페로몬 트랩에 교미하지 않은 수컷이 시험기간 중에 포획되지 않았다. 대조구인 교미하지 않은 암컷 성충을 장착한 트랩에서도 교미하지 않은 수컷 성충은 포획되지 않았다. 비록 실내에서 교미한 수컷 성충은 성페로몬 성분에 대해 교미하지 않은 수컷 성충처럼 촉각 반응을 보였다고 할지라도 실제 야외 망실 하우스에서 교미를 한번 한 수컷 성충은 비행 능력 등 활력의 문제로 트랩에 포획되지 않았을 가능성이 있다고 생각된다. 야외 노지에서 열대거세미나방 성페로몬에 대한 수컷 성충의 유인 정도는 추후 좀 더 많은 검토가 필요할 것으로 본다.

  • We, at The Korea Democracy Movement Archives opened temporarily at SungKongHoe University(SKHU), have currently collected about 100,000 recorded materials of democratization movement related with labor, farmer, civilian, human rights, peace, unification, young people, student and women's movements by investigating, collecting and receiving donations from civil organizations and individuals, and about 70,000 data out of this 100,000 data were converted into computer files. The Korea Democracy Movement Archives(temp) at SKHU has a significance in that it is the first archive opened by an organization. Furthermore, the opening of this Archive means the expansion of awareness on recording culture and accumulation of the achievements of the democratization movement in Korea. However, many obstacles still remain in the establishment of this Archive in a full-scale. This article examined many theoretical and realistic obstacles posed to the archivists, who are the professionals responsible for record management, in process of establishing the Archive, and the role and future perspectives of the archivists at The Korea Democracy Movement Archives(temp). The first obstacles in the process of organizing and separating the recorded materials at the Archive is a difficulty in the description of classifying the different movement organizations. The second obstacle is a difficulty in specifically applying the international standard, ISAD(G), of record description in the process of establishing the description items. Through many trials and errors, we need to try to confirm the description befitting. The Korea Democracy Movement Archives through continuous adjustment and complementary measures. The third obstacle is a difficulty in estimating the range and physical and quantitative amount of the recorded materials since the collection of recorded materials is complete. Thus, the answers to these problems lie in continuous efforts to establish a creative classification system befitting the democratization movement in Korea in the process of many trials and errors and endeavor. The evaluation classification done by archivists is a creative act forming record heritage, and archivists need to form record heritage reflecting the evaluation system of a certain period. Moreover, they transmit the shape of the current era in a maximum scale to the future by using the minimum amount of records. An archivist is responsible for two tasks, i.e., preserving a record and making other people to utilize the record by working with record. However, We, at The Korea Democracy Movement Archives(temp), have an additional task of contributing to the democratization movement in korea that has not ended by collecting, preserving and making people to utilize the fragments of memory in the recent history of Korea by establishing the Archives.

  • In order to investigate the behavioral characteristics of Pacific cod (Gadus macrocephalus) released at the entrance of Jinhae Bay, Korea, the direction and range of movement, swimming speed of the fish were measured with an acoustic telemetry techniques in winter, 2015. Three wild Pacific codes WC1 to WC3 (total length 66.0, 75.0, 76.0 cm; body weight 2.84, 2.79, 3.47 kg, respectively) were tagged with the acoustic transmitter. WC1 tagged with an acoustic transmitter internally by surgical method, WC2 and WC3, externally with the acoustic data logger and a micro data logger for recording audible sound waves including timer release unit. The movement routes of the tagged fish were measured more than five hours using VR100 receiver and a directional hydrophone. The directionality of the fish movement was tested by Rayleigh's z-Test, the statistical analysis, and a statistical program SPSS. Three tagged fishes were individually released on the sea surface around the entrance to the Jinhae Bay on 10 to 24 January 2015. WC1 moved about 13.32 km with average swimming speed of 0.63 m/s for six hours. The average swimming depth and water depth of the seabed on the route of WC1 were 7.2 and 32.9 m, respectively. The movement range of WC2 and WC3 were 7.95 and 11.06 km, approximately, with average swimming speed of 0.44 and 0.58 m/s for 5.1 and 5.3 hours, respectively. The average swimming depth of WC2 and WC3 were 18.7 and 5.0 m, and the water depth on the route, 34.4 and 29.8 m, respectively. Three fishes WC1 to WC3 were shown significant directionality in the movement (p < 0.05). Movement mean angles of WC1 to WC3 were 77.7, 76.3 and $88.1^{\circ}$, respectively. There was no significant correlation between the movement direction of fish (WC1 and WC2) and the tidal currents during the experimental period (p >= 0.05). Consequently, three tagged fishes were commonly moved toward outside of the entrance and headed for eastward of the Korean Peninsula, approximately, after release. It may estimate positively that the tidal current speed may affect to the swimming speed of the Pacific cod during the spring tide than the neap tide.

  • This study investigates the Gabo Jaedong Jemuljeongnyechaek, which is the recording of the darye executed over a period of a year in 1834 ($34^{th}$ year of reign by King Sunjo) in the latter part of the Joseon Dynasty, two years after the death of Princess Bokon, the $2^{nd}$ daughter of King Sunjo. Accordingly, we examined the types of darye (tea ceremonies) and the characteristics of the composition of foods at ancestral rites of the royal families of Joseon. Moreover, we also analyzed the cooking methods and characteristics of food terminologies used in the darye. This includes 39 categories of food and ingredients used for tea ceremonies held for one year, on behalf of the deceased Princess Bokon in 1834. The darye for the monthly national holiday was held along with the darye on the $1^{st}$ and the $15^{th}$ day of every month. The darye for rising up and the birthday darye were held on May $12^{th}$ and October $26^{th}$ of the lunar calendar, being the anniversaries of the death and the birth of Princess Bokon, respectively. The birthday darye and the darye for New Year's Day, Hansik ($105^{th}$ day after winter solstice), Dano ($5^{th}$ day of the $5^{th}$ month of the lunar calendar), and Thanksgiving "Chuseok" were held in the palace and at the burial site of the Princess. During the darye for rising up in May and the Thanksgiving darye at the burial site in August, rituals offering meals to the deceased were also performed. The birthday darye at the burial site of Princess Bokon featured the most extensive range of foods offered, with a total of 33 dishes. Foods ranging 13~25 dishes were offered at the national holiday darye, while the darye on the $1^{st}$ and the $15^{th}$ of the month included 9~11 food preparations, making them more simplified with respect to the composition of foods offered at the ceremony, in comparison to the national holiday darye. The dishes were composed of ddeok, jogwa, silgea, hwachae, foods such as tang, jeok, jjim, hoe, and sikhae, and grain-based foods such as myeon, mandu, and juk. Foods offered at the burial site darye included 12~13 dishes comprising ban, tang, jochi, namul, chimchae, and jang. Meals offered at the darye had a composition similar to that of the daily royal table (sura). Darye recorded in the Jemuljeongnyechaek displayed characteristics of the seasonal foods of Korea. Jemuljeongnyechaek has detailed recordings of the materials, quantities, and prices of the materials required for preparations of the darye. It is quite certain that Jemuljeongnyechaek would have functioned as an essential reference in the process of purchasing and preparing the food materials for the darye, that were repeated quite frequently at the time.
