Short‑Term Load Forecasting Based on Deep Neural Networks Using LSTM Layer
Bo‑Sung Kwon,Rae‑Jun Park,Kyung‑Bin Song 대한전기학회 2020 Journal of Electrical Engineering & Technology Vol.15 No.4
Short-term load forecasting (STLF) is essential for power system operation. STLF based on deep neural network using LSTM layer is proposed. In order to apply the forecasting method to STLF, the input features are separated into historical and prediction data. Historical data are input to long short-term memory (LSTM) layer to model the relationships between past observed data. The outputs of the LSTM layer are incorporated with outputs of fully-connected layer in which prediction data, for instance weather information for forecasting day, are input. The optimal parameters of the proposed forecasting method are selected following several experiment. The proposed method is expected to contribute to stable power system operation by providing a precise load forecasting.

Objectives: As interest in wellness tourism is increasing in Korea, we sought to propose a program with Korean Medicine Contents for eight resorts in Gangwon-do, which has forests and marine resources. Methods: The authors visited eight designated resorts in Gangwon-do, observed the facilities, and interviewed the people in charge. Questions and answers were asked and answered in the form of a questionnaire regarding any deficiencies in the interviews. Afterwards, the contents were analyzed and a Korean Medicine program suitable for each resort was proposed. Results: A total of 17 Korean Medicine Programs were proposed, of which the meditation/yoga program and diet/drink program tailored to each constitution were proposed to be applicable to all 8 resorts. The rest were proposed considering each resort's facilities, environmental characteristics, and main product programs. Conclusions: It appears that the ‘meditation/yoga program’ and ‘constitutional diet and beverage development’ sectors are programs that can be commonly carried out by all facility companies, and for this purpose, the Sasang constitution test and Korean medicine measurement within the resort in Gangwon-do are used to create a program linked to this. In addition, we believe that efforts to improve the program through verification of efficacy will be necessary in the future

Electrophoretic variations in isozymes encoded by 16 loci were studied to estimate genetic variation and to assess phyletic relationships, and biogeographic pattern of distribution of the Euphaedusa fusaniana collected from Sehwa, Aeweol, Samchuck, Tongdosa, Gernundo, and Y?su areas in Korea was discussed with respect to the isozyme variation. The 180 apecimens were examined. Means of allele per locus(?) and polymorphism(?) were 1.528 and 45.5%, respectively and hetrozygosity (?_(D)) was 0.205. Samchuck population showed lower mean value of allele per locus(?=1.46). Higher polymorphism(P=57.14%) was observed among Tongdosa popualtion. Aeweol population showed slightly lower genetic variation (H_(D)=0.15) than others. Average genetic similarities(?) among the six populations was 0.716 Aeweol and Samchuck populations were genetically closer(S=0.903) than others. However the S value between Y?su and Samchuch populations was low(S=0.562). Average genetic distance(?) among the 6populations were 0.267. Both Aeweol and Samchuck populations have closer genetic distance (D=0.067). Genetic distance pattern was similar to genetic similarity pattern.

ISO 18000-6B, EPC Class-1 Gen-1, Gen-2 리더 표준에 적용되는 UHF 대역 RFID 리더용 RF 송신기를 하이브리드형 DHC로 설계 및 제작하였다. 송신기의 ASK 변조회로는 하나의 GaAs SPST스위치와 LPF로 구성하였으며, PR-ASK 변조 회로는 하나의 balua 두 개의 GaAs 통PST와 하나의 GaAs SPDT 스위치를 이용하여 link주파수 1-MHz 이상되는 변조신호에서 시간 지연이 없도록 설계하였다. LDMOS를 이용한 전력증폭기는 선형성을 위하여 8-dB back-off 상태로 동작시켜 출력전력 30-dBm을 얻었다.

이(lice)는 인체에 기생하면서 그들의 생활을 영위하고 여러 가지 질병을 전파하는 매개체로서 널리 알려져 온절족동물의 일종이다. 과거에는 인체에 발생하는 많은 질병의 매개체가 되었으나 그동안 의식주의 개선,공중 및 개인위생의 향상으로 최근에는 인체기생의 빈도가 많이 줄었으며 따라서 이에 의한 질병의 발생도 많이 감소하였다. 더욱이 안검을 침범한 음모이의 국내에 보고된 증례는 1976년 백 등이 보고한 2례, 1977년 신 등이 보고한 1례, 1996년 이 등이 보고한 1례, 1997년 김 등의 1례로 총 5례 뿐이다. 저자들은 세극등과 광학현미경 검사로 음모이에 의한 안검염으로 확진한후,세극등을 이용한 물리적 제거와 항생제 안약 및 연고의 도포를 하며 총 4주간 추적관찰을 하였으며 이 기간동안추가적인 음모이의 성충이나 충란의 발견이 없는 좋은 치료 결과를 경헝하였기에 이를 보고하는 바이다. We have experienced with a rare case of blepharitis caused by pubic lice, which was confirmed by slit-lamp and light microscopic examinations and resulted with a good outcome with appropriate treatment as follows. A two year old male child complained of foreign body sensations bilaterally, and an itching sensation at both upper and lower eyelids for 2 months. He was diagnosed with blepharitis caused by pubic lice after observation of adult louse and nits on slit-lamp examination. The treatment was accomplished by mechanical removal of the lices and nits by forceps and antibiotic eyedrops and ointment were applied to both eyes. The morphologic evaluation was performed with slit-lamp and light microscopy. The follow-up interval was a week for next one month and no louse or nit was found under slit-lamp examination. So we decided that the pubic lice was completely removed.

Emphysematous cystitis is an uncommon disease in which bacterias produce gas within the bladder wall and surrounding tissue. Patients with diabetes, neurogenic bladder and chronic urinary tract infection are predisposed to the disease. It is usually caused by E.coli and Klebsiella. Severity of illness ranges from an asymtomatic condition to life threatening cystitis. Succesful management depends on early diagnosis with correction of underlying causes, administration of appropriate antibiotics, establishment of adequate bladder drainage and surgical excision of involved tissue when required. We report a case of 52-year-old woman who did not compain of symtoms of cystitis but epigastric pain, nausea, and vomitting. Emphysematous cystitis was revealed on the abdominal X-ray series incidentally. CT scans of the pelvis showed mottled gas bubble within the bladder. After treatment, the symtoms subsided and plain abdominal film showed no evidence of gas shadow in the pelvic cavity.
