Inclusion effect of soybean meal (SBM) and fermented SBM (FSM) in extruded pellet for juvenile abalone (Haliotis discus) was compared in abalone farm. Dietary inclusion effect of the combined macroalgae (MA) (Undaria pinnatifida and Hizikia fusiforme) and a single Saccharina japonica on abalone was also compared. Three thousand six hundred juvenile abalone were purchased from a private hatchery and acclimated to the experimental conditions for 2 weeks. Six 5-ton flow-through raceway tanks were used, and abalone were randomly distributed into tanks (n = 600 per tank). Three experimental diets were prepared in duplicate. Fish meal, FSM, corn gluten meal, and shrimp meal and wheat flour and dextrin were used as the protein and carbohydrate sources, respectively, in the FSM diet. MA was also included in the FSM diet. FSM and MA in the FSM diet were substituted with SBM at the expense of wheat flour and S. japonica, referred to as the SBM and SJ diets. The experimental diets were pelletized by an extruded pelleter. Water stability of nutrients in the experimental diets was monitored at 12, 24, and 48 h after seawater immersion. The experimental diets were fed to abalone once a day to satiation with a little leftover for 120 days. The retained crude protein and lipid and ash content of the extruded pellets were changed over all period of time. Weight gain and specific growth rate (SGR) of abalone fed the SBM diet were greater than those of abalone fed the FSM and SJ diets. Weight gain and SGR of abalone fed the SJ diet were also greater than those of abalone fed the FSM diet. The longest shell length, widest shell width, highest shell height, and greatest soft body weight were obtained in abalone fed the SBM diet, followed by the SJ and FSM diets. Proximates of the soft body of abalone were not different among the experimental diets. In conclusion, SBM was a superior protein source to FSM in extruded pellet for growth performance of abalone. Dietary inclusion of a single S. japonica was superior to the combined inclusion of U. pinnatifida and H. fusiforme in the production of abalone.

The effects of dietary antioxidant [saltwort (SW), leek (LK), and dandelion (DD)] supplementation on the growth, body composition, serum chemistry, and challenge test results of juvenile rockfish, Sebastes schlegelii, were determined. In an experiment, 320 fish were randomly distributed into eight, 50-L flow-through tanks (40 fish per tank). Four experimental diets were prepared: the control diet (Con) with synthetic antioxidant: and diets with SW, LK, or DD from natural sources. Each diet was randomly assigned to duplicate tanks of fish, which were hand-fed to satiation twice daily for 8 weeks. After the 8-week feeding trial, 20 fish from each tank were artificially infected with Streptococcus iniae and monitored for 6 days. The dietary additives did not affect survival, weight gain, specific growth rate, feed efficiency (FE), protein efficiency ratio (PER), or plasma chemistry. However, the cumulative mortality of fish fed the SW, LK and DD diets was lower than that of fish fed the control diet beginning 4 days after infection. In conclusion, dietary supplementation with SW, LK, and DD did not affect the growth, FE, PER, or plasma chemistry of rockfish. However, dietary inclusion of SW, LK, and DD lowered the mortality of rockfish following infection with S. iniae.

We investigated the effect of replacing tuna byproduct meal (TBM) and rice bran (RB) with fish meal (FM) and macroalgae (MA) in extruded pellets (EP) supplied as a diet to juvenile Abalone Haliotis duscus in aquaculture. In total, 80,000 juvenile abalone were distributed among eight indoor raceways and supplied with one of four experimental diets. The control diet consisted of FM, fermented soybean meal, corn gluten meal and shrimp meal as protein sources, with wheat flour and dextrin as carbohydrate sources; the control diet also contained MA. In the FM50 diet, TBM was replaced with 50% FM. In the MA 50 diet, RB was replaced with 50% MA. The final diet, FM50+MA50, included TMB and RB in place of 50% FM and 50% MA. Abalone were fed to satiation with little food leftover for 16 weeks. Weight gain and specific growth rate of abalone fed the control diet were greater than those of abalone fed the FM50 and MA50 diets, but not different from those of abalone fed FM50+MA50 diet. The proximate composition of abalone soft body did not vary according to experimental diets. Based on these results, it appears that the traditional commercial diet for juvenile abalone, comprising FM and MA, could be replaced with one containing 50% TBM and 50% RB without any retardation of growth.

정금나무(Vaccinium oldhamii Miq.)의 다신초 유도 및 기외발근을 통한 식물체 재분화

In vitro techniques were developed for propagating Vaccinium oldhamii using shoots with apical buds. Explants having an apical bud were cultured on Murashige and Skoog (MS) medium supplemented with 1.0, 2.0, and 5.0 mg/L of each zeatin, thidiazuron, 6-benzylaminopurine (BA), and 6-(γ,γ-dimethylallylamino)purine (2-iP) in order to induce multiple shoots. Among the tested treatments, the 2.0 mg/L of 2-iP proved to be most suited for the multiplication and growth of shoots; the multiple shoot induction rate was 100.0%, the average number of shoots was 7.4 per explant, and the average shoot length was 51.7 mm. The in vitro elongated shoots were rooted on half-strength MS medium containing various concentrations of indole-3-butyric acid (IBA) and 1-naphthaleneacetic acid (NAA). However, overall callus overgrowth was observed in all treatments and resulted in necrosis and abnormal shoot growth in root formation. A low concentration (0.5 mg/L) of IBA was appropriate for normal root development and the in vitro rooting rate was 30%. Ex vitro treatments on root formation using various concentrations of IBA with Talc powder and two types of rooting substrates (Flexi-Plugs or Horticultural soil) were examined. The ex vitro rooting rate (80%) and length of roots (32.9 mm) were obtained when the cut ends of the shoots were treated with 1.0 mg/L IBA and cultivated in Horticultural soil for 2 months. These findings suggest that ex vitro rooting is the more effective method for improving root formation in Vaccinium oldhamii than in vitro rooting.

Decrease of occlusal vertical dimension (OVD) due to loss of teeth structure and destruction of the occlusal plane by severely worn dentition may cause cross bite or temporomandibular joint disorder by following change of facial feature or the loss of anterior guidance. Full mouth rehabilitation via an increase of the OVD can be considered to avoid this problem and proper evaluation of patient's OVD is essential. An 80 year old male visited for overall prosthodontic treatment, cross bite due to continuous wear and following decrease of the OVD were observed. We analyzed the existing occlusal relationship using the diagnostic cast, the radiographic evaluation and clinical test, and then proper increase of OVD was selected. The new OVD on diagnostic wax up was placed by the temporary restoration. After 3 months of observation period, final restoration with fixed partial dentures and implant overdenture were made. Throughout the follow-up period of 8 months, the aesthetic and functional improvement can be obtained.

Associations between Pathological Internet Use and Depression, Anxiety, and Suicidality among College Students

윤아영,정영은,김문두 대한우울조울병학회 2020 우울조울병 Vol.18 No.2

Background: The Internet has become an important global tool used by diverse age groups, especially adolescents and young adults. However, in South Korea, studies on the prevalence of pathological Internet use (PIU) among college students are limited to being compared with those involving adolescents. Therefore, in this report, we assessed the pervasiveness of PIU and its related factors among college students. Methods: Data were collected from 1,390 college students. PIU was screened using the Self-Report Scale for Measuring Behavior Symptoms of Adults’ PIU. We analyzed the associations between PIU and depression, anxiety, and suicidality. We also used the self-report questionnaire to assess sociodemographic and other clinical factors. Results: Of the total number of participants, 16.8% (n=234) were identified as problematic Internet users. Univariate analysis revealed significant associations between depression, anxiety, suicidal behavior, and PIU. Multivariate analysis further showed a significant relation between unsatisfactory school life (odds ratio [OR], 2.56; 95% confidence interval [CI], 1.06-6.15; p=0.036), depression (OR, 1.67; 95% CI, 1.03-2.71; p=0.036), and anxiety (OR, 3.36; 95% CI, 1.91-5.93; p<0.001) with PIU. Conclusion: Depression, anxiety, and suicidality are common in individuals engaged in PIU, with a complex interrelation. Further studies are required to clarify the mechanisms of PIU and develop preventive and treatment strategies.

시용향악보고려가요의 수록배경 추론 -<상저가>, <풍입송>, <야심사>를 중심으로-

윤아영 한국국악학회 2023 한국음악연구 Vol.74 No.-

The purpose of this study is to estimate the relationship the three Goryeo songs of <Sangjega>, <Pungipsong>, and <Yasimsa> with rituals, and how they are included separately from other Goryeo songs on the music book Singyonghyangakbo. <Sangjega> is a representative song that reflects the social conditions by the phrase Hwanggyeondapdae in the unique expletives of the Goryeo Dynasty, and its connection with the ritual of narye at the end of year was presented. In addition, the Goryeo songs <Pungipsong> and <Yasimsa> are editorials meant to commemorate the king, and are representative songs that have been played at a feast for envoys and among them, <Yasimsa> is considered to have been related to the tradition of Hwasandae, a unique object of the guanwha ritual. Unlike other Goryeo songs in the same music book, it is very unusual that the three songs of <Sangjega>, <Pungipsong>, and <Yasimsa> are included between <Sanggayoryang> as a marching music and <Sungwhangban> related to the ritual of expelling evil. The reason why they were included in this way is presumed to be because they were included according to consciousness related to guanwha ritual, it is reasonable to be located between gwanna and guna, and the location where this was reflected corresponds to the order of the 13th to 15th songs. It is still difficult to find solid evidence as to whether the three songs known as Goryeo songs were included in the Singyonghyangakbo as they were, but unlike the sequential descending ending type, which is known as a unique characteristic of ritual music such as Ahak and Gochiak, in the original form can be put more weight on the possibility that it was included as it was in the original form. In other words, three songs, which are <Sangjega>, <Pungipsong>, and <Yasimsa> were sungs or related to the performances of gwanhwa among the narye ceremonies of the king Yeonsan-gun, and all of the songs are believed to have been included in the original form since the Goryeo Dynasty. The estimation of the background and use of the songs covered in this study has many limitations in that there are not enough literature data to prove, but it is significant in that it is an attempt to interpret the complexity of Singyonghyangakbo in many ways.
